RadTensor: A Vendor-Neutral Radiology Intelligence Subnet on Bittensor

Executive Thesis

RadTensor connects real-world radiology workloads -- measured in billions of imaging exams per year and billions of dollars in AI spend -- to the Bittensor network through a compliant, vendor-neutral gateway and dedicated subnet. By turning existing hospital and clinic AI budgets into usage-based, TAO-denominated demand, RadTensor is designed to become Bittensor's first truly enterprise-scale fiat subnet: a high-volume, regulator-aligned income engine backed by mandatory clinical workflows rather than speculative traffic.

Abstract

RadTensor is a vendor-neutral radiology intelligence subnet on the Bittensor network, designed to integrate advanced computational technologies -- primarily artificial intelligence (AI), with optional quantum acceleration -- directly into radiology workflows. The gateway architecture and workflow pattern are derived from, and aligned with, the patent-pending QRad vendor-neutral radiology integration system (US Patent Application No. 63/720,155), controlled by the project lead, and here adapted for decentralized operation on Bittensor. The subnet enables healthcare providers to submit imaging workloads into the Bittensor ecosystem while maintaining full compatibility with existing systems such as Picture Archiving and Communication Systems (PACS) and Vendor Neutral Archives (VNAs), using a vendor-neutral gateway rather than requiring disruptive changes to on-premise infrastructure.

RadTensor exposes a modular, scalable, radiology-focused marketplace in which miners and validators compete to process de-identified imaging studies. Clinical sites select computational workflows based on specific clinical and operational requirements (for example triage, quality assurance, anomaly detection, and structured reporting), while the subnet's incentive layer distributes TAO-denominated rewards according to measured diagnostic performance, reliability, and compliance. The design supports interoperability across multiple vendor systems and model providers, mapping the existing QRad marketplace concept directly onto Bittensor's miner/validator architecture.

At its core, RadTensor employs a secure, API-based framework engineered for medical imaging data. An on-premise gateway handles de-identification, adaptive encryption, and DICOM-aware routing before cases are submitted to the subnet. On-chain, ledger-backed compliance logging and validator logic enforce HIPAA-aligned and DICOM-compliant handling of all tasks, while cross-subnet integrations can leverage indexing subnets, inference-heavy subnets such as Chutes-class for scalable GPU compute, coordination subnets such as Affine-class for cross-subnet composition and safety, and optional quantum-compute subnets for future advanced workloads. The system is designed for deployment in diverse healthcare environments -- from large hospital networks to small outpatient clinics, urgent care centers, and rural imaging facilities.

By integrating advanced AI (and future quantum) capabilities into radiology workflows through an open, incentivized subnet rather than centralized edge-compute or proprietary SaaS platforms, RadTensor reduces per-site cost, removes vendor lock-in, and enables structured data exchange within existing regulatory frameworks. This architecture is intended to benefit not only individual healthcare providers but the broader Bittensor network, by turning real-world radiology workloads into a continuous, high-value proof-of-effort signal that strengthens both the RadTensor subnet and the surrounding AI and indexing subnets over time.

Technical Field and Background

[001]The present project pertains to the field of medical imaging systems and computational diagnostics within decentralized AI networks, specifically addressing the integration of advanced computational technologies into radiology workflows via the Bittensor protocol. It describes RadTensor, a vendor-neutral radiology intelligence subnet that acts as an intermediary layer between healthcare providers, radiology-specific imaging repositories, and a global marketplace of Bittensor miners and validators running artificial intelligence models, with optional access to quantum-capable subnets.

[002]Through its modular, API-based gateway and subnet architecture, RadTensor ensures compatibility with diverse radiology systems while providing dynamic, scalable access to decentralized computational resources tailored to imaging workflows. Instead of routing cases to centralized service providers, RadTensor converts radiology workloads into on-chain tasks that are priced, evaluated, and rewarded in TAO across the Bittensor network, addressing persistent challenges including data interoperability, regulatory compliance, and scalability.

[003]Data Interoperability: Radiology infrastructures rely heavily on legacy systems such as PACS, VNAs, and hospital RIS, which are not natively designed to connect to decentralized AI networks. RadTensor bridges the gap between these systems and the Bittensor subnet ecosystem through a vendor-neutral gateway that speaks DICOM on-premise and structured task formats on-chain.

[004]Regulatory Compliance: Imaging workflows must comply with global standards such as HIPAA, GDPR, and DICOM. Many existing infrastructures lack robust de-identification pipelines, adaptive encryption, and real-time compliance monitoring, particularly when interacting with external AI services. The RadTensor gateway enforces de-identification, controlled data flow, and policy-aware validator logic, while leveraging Bittensor's blockchain substrate or equivalent ledger mechanisms for immutable logging of critical events.

[005]Scalability and Access: Conventional imaging systems are not built to leverage multiple AI or quantum providers in parallel, and they rarely expose standardized task interfaces suitable for subnet-based marketplaces. This limits access to cost-effective, high-performance compute and locks clinics into single-vendor contracts. RadTensor instead treats compute as a competitive marketplace across Bittensor subnets -- routing tasks to radiology-focused miners on RadTensor itself, to inference-heavy subnets such as Chutes-class, coordination layers such as Affine-class, and, where appropriate, to quantum-capable subnets -- without tying providers to any single proprietary stack.

[006]RadTensor enhances the security and compliance of imaging data exchanges through an on-premise gateway implementing adaptive encryption protocols and compliance logging tailored for HIPAA and DICOM adherence. Protected health information (PHI) is stripped or tokenized before any task reaches the subnet, and validators are required to enforce output and behavior constraints. These mechanisms protect PHI while maintaining strict compliance with global regulations and aligning with radiology's unique operational and legal constraints.

[007]Designed for universal applicability, the RadTensor architecture scales seamlessly across diverse healthcare environments -- from rural clinics with limited infrastructure to advanced urban hospitals with high-volume radiology departments. By serving as a bridge between traditional imaging systems and Bittensor's AI and quantum-capable subnets, RadTensor optimizes and enriches imaging data for clinical diagnostics without disrupting established workflows.

[008]Its vendor-neutral architecture eliminates dependency on proprietary infrastructure and single-vendor AI solutions, allowing healthcare providers to access a competitive pool of miners and models rather than being locked into rigid, long-term SaaS or edge-compute contracts. Within RadTensor, radiology clinics configure and select computational services -- triage, anomaly detection, QA, structured reporting -- based on specific clinical and operational needs, while the subnet's incentive and weighting mechanisms direct TAO rewards toward the most accurate, reliable participants. This open, modular framework supports continuous technological innovation across the Bittensor network and is designed to accommodate emerging subnets, new imaging modalities, and evolving computational standards.

Background and Prior Art

[009]The field of diagnostic radiology has seen major advances in imaging hardware and software, improving diagnostic accuracy and clinical decision-making. Yet the way imaging data is managed and processed still blocks the full potential of these innovations. Most radiology workflows are anchored to PACS and VNAs. While these systems are widely deployed and stable, they remain poorly integrated with modern computational stacks -- especially decentralized AI networks and emerging quantum resources. Today, access to advanced AI for radiology is typically delivered through expensive, centralized SaaS or edge-compute platforms that are tightly coupled to single vendors, rigid contracts, and proprietary infrastructure. This lack of seamless, vendor-neutral integration with scalable computational services restricts the incorporation of new models and methods, leading to underutilized imaging data, high per-site costs, and slow adoption of computational enhancements across small clinics, urgent care centers, and resource-constrained healthcare environments.

[010]Many radiology infrastructures are constrained by proprietary PACS, VNA, and edge-compute architectures that limit integration with external computational services. These systems often lack modular, API-driven extensibility and are tightly bound to single-vendor AI platforms, making it difficult to interface with competitive, rapidly evolving AI capabilities -- let alone decentralized networks like Bittensor or emerging quantum-enabled services. As a result, healthcare providers are locked into static, resource-intensive workflows with high recurring costs and limited flexibility, unable to easily scale or swap in better models as clinical demands, budget pressures, and computational imaging technologies evolve.

[011]Limited interoperability and vendor lock-in affect several critical aspects of radiology workflows, including real-time compliance validation, decentralized AI integration, adaptive data routing, and scalability. Institutions struggle to dynamically adapt to evolving regulatory requirements, to incorporate external AI diagnostic tools, to distribute workloads intelligently across diverse computational resources, and to integrate emerging AI and quantum technologies into traditional PACS-based environments. These structural limitations prevent radiology departments, especially smaller clinics and urgent care centers, from benefiting from Bittensor's incentive-aligned, competitive compute market, where RadTensor is explicitly designed to operate.

[012]Advanced AI and quantum-enabled methods offer major opportunities to enhance medical imaging -- ranging from anomaly detection and triage to protocol optimization and diagnostic decision support. However, integrating these computational methods into real-world radiology workflows, especially in a decentralized context, presents several challenges: ensuring data security and compliance, achieving scalable, vendor-neutral interoperability, and preserving workflow integrity and reliability in the face of complex model pipelines.

[013]Existing literature and commercial systems highlight significant gaps in computational integration that RadTensor is designed to address. Major radiology bodies and industry reports describe current PACS and VNAs as monolithic and vendor-dependent, often requiring each AI vendor to build custom integrations per system. Research on quantum computing in medical imaging discusses potential benefits for image enhancement and optimization but typically treats quantum systems as stand-alone experimental pipelines without practical interoperability with existing radiology infrastructure. Regulatory and operational analyses emphasize that vendor-specific integrations, opaque model behavior, and lack of standardized logging and monitoring slow AI adoption. Studies on high-performance and quantum computing for imaging confirm that while these technologies can reduce processing times and enable more complex algorithms, existing architectures are not structured to treat compute as an external, dynamic resource that can be selected, benchmarked, and compensated on a per-task basis.

[014]Collectively, these observations show that while AI and quantum computing hold significant promise for radiology, existing approaches do not solve the fundamental problem: a vendor-neutral, scalable, compliance-driven integration layer that can orchestrate multiple computational service providers, reward them based on measurable value, and operate across diverse clinical environments. RadTensor is proposed to fill this gap by implementing that integration layer as a Bittensor subnet, turning radiology workloads into a continuous, incentivized proof-of-effort signal within the broader network.

Summary of the RadTensor Subnet

[015]To address these challenges, the present project introduces RadTensor, a vendor-neutral radiology intelligence subnet on Bittensor that operationalizes the QRad gateway pattern as a decentralized, incentive-aligned integration layer. Instead of building custom point-to-point integrations for each AI or quantum service, RadTensor exposes a standardized task interface to PACS and VNAs on one side and a competitive marketplace of Bittensor miners and validators on the other.

[016]RadTensor's Gateway and API Core Framework serves as the central hub for managing and orchestrating diagnostic imaging data between traditional radiology systems and the subnet. Imaging studies are ingested from PACS and VNAs, de-identified and transformed into structured tasks, and then distributed to miners running specialized imaging models. Validators evaluate miner outputs against gold-standard datasets, ensemble references, and compliance policies, and they adjust miner weights and rewards accordingly. Over time, this creates a continual competition among models and providers to deliver better performance at lower cost.

[017]The subnet is designed around a radiology-focused marketplace in which healthcare providers configure workload profiles and preferences rather than selecting individual vendors. Providers define modalities, tasks (for example chest X-ray triage or CT brain hemorrhage detection), performance thresholds, and cost or latency constraints. RadTensor translates these configurations into routing and weighting policies, using real-time performance and compliance metrics to determine which miners and routes are favored.

[018]The gateway enforces de-identification, encryption, and logging before any data reaches the subnet. PHI remains on the healthcare provider's side, while only de-identified imaging-derived tensors or compressed representations are sent for processing. All critical events -- task creation, miner participation, validator decisions, reintegration -- are recorded in an immutable or append-only ledger, providing auditability and supporting regulatory reviews.

[019]RadTensor is designed to be deployed in hybrid-cloud configurations, with on-premises components sitting close to PACS and VNAs to handle DICOM ingestion and PHI protection, and subnet connectivity handled through secure, policy-aware channels. This allows small outpatient clinics and large hospital networks alike to benefit from the same global pool of computational providers without re-architecting internal systems.

[020]Financially, RadTensor is structured to support usage-based pricing aligned with existing AI imaging economics. Institutions pay per processed exam or per task bundle, while miners and validators receive TAO-denominated rewards for their contributions. By capturing a fraction of the multi-billion-dollar AI imaging spend and routing it through the Bittensor incentive layer, RadTensor has the potential to become a major external revenue source for the network, while simultaneously delivering tangible clinical value.

Best Mode for Carrying Out the Subnet

[371]The best mode for carrying out the present design is the implementation of RadTensor as a vendor-neutral gateway plus Bittensor subnet architecture for integrating decentralized AI and optional quantum computational services into medical imaging workflows. In this mode, the RadTensor Gateway / API Core Framework (003) sits alongside existing PACS and VNAs, transforming radiology studies into de-identified, structured tasks that are sent to the RadTensor subnet for processing and then safely reintegrated into clinical systems.

[372]The preferred embodiment consists of a modular, API-driven gateway framework tightly integrated with PACS and VNAs, combined with a dedicated RadTensor subnet on Bittensor that hosts miners and validators specialized in radiology workloads. Radiologists and institutions interact through the Client Access Node (004) and marketplace module (003a), dynamically configuring AI task types and policies without being constrained by any single vendor. The gateway is engineered for near-real-time task formation, adaptive encryption (003d), and compliance-driven processing (003e, 003f), ensuring secure handling of imaging data in line with HIPAA, GDPR, and DICOM standards while only de-identified data ever reaches the subnet.

[373]The optimal implementation includes the RadTensor marketplace logic (003a) functioning as a radiology-focused digital ecosystem where computational providers -- primarily RadTensor miners -- compete to offer AI-powered image enhancement, triage, anomaly detection, QA, and structured report assistance. Optional quantum-assisted processing (006) can be integrated for specific optimization tasks. The Dynamic Routing Engine (003f) prioritizes processing efficiency by intelligently allocating workloads and TAO-denominated rewards based on diagnostic performance, latency, cost-effectiveness, validator scores, and regulatory requirements.

[374]In a practical deployment scenario, the RadTensor gateway is hosted in a hybrid cloud configuration: on-premises components sit close to PACS and VNAs (002, 002a) to handle DICOM ingestion, de-identification, and encryption, while the gateway maintains secure connections to Bittensor nodes for subnet interaction. This architecture scales across multiple healthcare facilities and supports diverse infrastructures without re-architecting core PACS infrastructure.

[375]Security and compliance remain at the core. The Adaptive Encryption Module (003d) applies quantum-resilient encryption. The Compliance Logger (003e) provides a ledger-backed audit trail for all critical actions -- task creation, miner and validator participation, reintegration events -- ensuring full traceability.

Industrial Applicability

[377]The RadTensor design is industrially applicable within the medical imaging and healthcare technology sectors, specifically for radiology workflow enhancement using decentralized AI infrastructure. By offering vendor-neutral access to AI and optional quantum-related computational processing via a Bittensor subnet, RadTensor addresses critical challenges in medical imaging interoperability, regulatory compliance, cost, and computational scalability.

[378]The system is applicable to a variety of healthcare environments, including large hospital networks, outpatient imaging centers, private radiology practices, teleradiology groups, and research institutions. The marketplace and policy layer (003a) serves as a central coordination hub for integrating advanced subnet-based computational services.

[379]The scalability ensures adaptability across urban hospitals with high imaging volumes and rural clinics with limited on-site computational resources. The hybrid deployment model allows institutions to keep imaging data and PHI on-premises, while leveraging the RadTensor subnet for heavy AI inference.

[381]Beyond healthcare, RadTensor's modular gateway plus subnet architecture can be adapted for other industrial sectors that require high-performance, compliance-sensitive image or signal processing -- including biomedical research imaging, pharmaceutical imaging analytics, predictive diagnostics, aerospace imaging diagnostics, geological imaging, industrial nondestructive testing, and forensic analysis.

Total Addressable Market and RadTensor Prospectus

[383]The scale of global diagnostic imaging provides the foundation for RadTensor's economic potential. Industry estimates indicate that approximately several billions of diagnostic imaging procedures are performed worldwide each year across modalities including X-ray, CT, MRI, and ultrasound. This volume forms a continuous stream of imaging data, much of which is underutilized from a computational standpoint and is an ideal substrate for an AI triage and enhancement layer such as RadTensor.

[384]Within this broader imaging ecosystem, the AI-in-medical-imaging segment already constitutes a substantial, rapidly expanding revenue pool. Recent market research places the global AI in medical imaging market in the low billions of USD in the mid-2020s, with projections reaching into the tens of billions of USD by the early-to-mid 2030s, corresponding to high double-digit compound annual growth rates.

[385]The present cost structure for AI in radiology is heavily centralized and capital intensive. Analyses of real deployments report implementation costs in the tens to hundreds of thousands of dollars per site. Some commercial AI radiology solutions price access on a per-study basis, with annual costs in the six-figure range at moderate monthly volumes. Quantum computing in healthcare is even more concentrated, with costs measured in the millions to tens of millions of dollars per installation.

[386]RadTensor is designed to invert this cost structure by decoupling access to high-performance imaging computation from local capital expenditure. Instead of purchasing dedicated AI servers, the RadTensor gateway connects PACS and VNAs to the Bittensor network and exposes AI as a metered, vendor-neutral service. Institutions pay a usage-based fee per processed exam, priced competitively relative to existing AI solutions, while avoiding additional per-user PACS license taxes and large up-front hardware purchases.

[388]The structural context within radiology is favorable. Imaging volumes are continuing to rise, and radiology departments face increasing workload pressure and staffing constraints. Many organizations are uncertain about return on investment for centralized AI solutions. This combination creates a clear opening for a vendor-neutral, pay-per-exam marketplace that can transparently compete on performance and cost.

[389]Within the Bittensor network, RadTensor represents a qualitatively different class of subnet from speculative or purely crypto-native workloads. Radiology imaging is mandatory, central to modern healthcare; imaging volumes are non-discretionary. The budgets that fund these procedures are embedded in national health systems and insurance structures. RadTensor is designed to be directly aligned with reimbursable clinical workflows.

[390]The market share capture path is conceptualized in staged terms. Phase 1 (Proof of Value): gateway deployed in high-volume early adopters covering a few million exams per year. Phase 2 (Regional Penetration): integration partnerships with PACS vendors, extending to tens of millions of exams. Phase 3 (Mature Scale): de facto standard routing layer for radiology AI, processing a nontrivial percentage of global volume.

RadTensor Architecture and Core Design Components

[392]The RadTensor architecture is built around a vendor-neutral gateway and subnet design that integrates existing radiology infrastructure with decentralized computational resources on the Bittensor network. The gateway ingests imaging studies from PACS and VNAs, de-identifies and structures them into tasks suitable for subnet processing, and routes these tasks to Bittensor miners. Throughout this process, the gateway maintains modular interoperability across on-premises, cloud, and hybrid infrastructures.

[393]Quantum capabilities are incorporated through an optional Quantum Processing Module that operates as an external layer rather than as a core subnet requirement, providing a secure interface for routing selected imaging-derived data to external quantum computing providers.

[394]The AI Processing Module is realized primarily through miners on the RadTensor subnet. These models are responsible for diagnostic insight generation, anomaly detection, triage scoring, quality assurance checks, and other computationally enhanced imaging tasks, designed to adapt dynamically to clinical requirements.

[395]The Compliance and Security Module operates at the gateway level, applying quantum-resilient encryption, PHI de-identification, and ledger-backed audit trails documenting each critical step of task creation, routing, processing, and reintegration.

[396]The Dynamic Routing Engine provides subnet-aware orchestration, continuously evaluating miner performance, resource availability, diagnostic urgency, and compliance mandates to allocate tasks appropriately.

[398]The dynamic workflow begins with receipt of diagnostic imaging data from PACS/VNAs via the marketplace-integrated API framework. Upon ingestion, encryption and automated PHI de-identification are applied. Tasks are dynamically routed to AI Processing miners and optional Quantum Processing services, processed, and returned through aggregation, validation, and enrichment. Final outputs are reintegrated into PACS or compatible repositories with full traceability.

Incentive and Mechanism Design

[410]The RadTensor subnet is designed around a radiology-specific proof-of-effort mechanism in which miners are rewarded for producing clinically useful outputs on real imaging tasks and validators are rewarded for accurately scoring and monitoring those outputs. The emission and reward logic is structured to ensure that value flows to participants who improve diagnostic performance and reliability while maintaining compliance.

[411]Emissions and fees are allocated among four primary groups: miners (majority share in proportion to performance), validators (accurate and timely scoring), data providers (contributing de-identified studies and labeled cases), and the subnet treasury (ongoing development, audits, and governance).

[412]Radiology proof-of-effort is defined at the task level. Each task corresponds to a specific imaging workload and includes inputs, expected outputs, and scoring criteria. Validators compute scores, update miner weights, and flag compliance or quality issues. Miner weights are adjusted based on rolling performance metrics, and reward shares are calculated via softmax over these weights.

[413]To discourage low-quality or adversarial behavior, RadTensor employs multiple safeguards. Tasks with known labels are regularly inserted as canary jobs. Validators monitor for PHI leakage and systematic bias. Miners that consistently underperform, leak PHI, or exhibit adversarial behavior have their weights reduced and can be subject to slashing.

[414]The high-level algorithm: (1) Gateway forms tasks and anonymizes them. (2) Marketplace and routing logic select miners. (3) Miners return outputs to validators. (4) Validators compute scores, update weights, flag issues. (5) Emissions distributed based on updated weights. This loop runs continuously, ensuring incentive alignment with clinical value.

Miner Design

[420]Miners on the RadTensor subnet execute AI models on de-identified radiology tasks. Each miner can specialize in particular modalities, body regions, or task types -- for example chest X-ray triage, CT brain hemorrhage detection, mammography screening, or QA on image orientation and labeling.

[421]Miner inputs are standardized: de-identified image data or derived feature tensors, minimal metadata (modality, body region), and a task specification. The payload excludes PHI and is compatible with a variety of model architectures.

[422]Outputs follow defined schemas: per-label probabilities for pathologies, structured anomaly flags, optional heatmap references or segmentation masks, natural language summaries, and calibration metrics or uncertainty estimates.

[423]Performance is evaluated across diagnostic accuracy, AUROC, latency, throughput, uptime, calibration quality, robustness, and compliance with output-format and PHI constraints. These metrics feed directly into validator scoring and weight updates.

Validator Design

[430]Validators score miner outputs, enforce quality and compliance constraints, and detect adversarial or low-value behavior. They form the backbone of the AI Error Handling and validation components.

[431]Validators maintain gold-standard evaluation sets composed of labeled retrospective cases and curated public datasets. They also maintain ensemble models or reference systems for each task type. Miner outputs are compared against gold-standard labels and ensemble predictions to compute scores.

[432]Scoring operates on both short-term and long-term windows. Short-term scores determine immediate adjustments. Long-term scores inform weight updates and routing decisions on a rolling basis. Validators also monitor for systematic bias, drift, and unusual behavior patterns.

[433]Validator incentives are structured so that accurate, timely, consistent validators receive emissions. Validators whose scoring deviates significantly from consensus have their own rewards reduced. This ensures alignment with both clinical accuracy and network integrity.

Go-To-Market Strategy

[440]The go-to-market strategy focuses initially on high-need, high-volume radiology segments where AI augmentation delivers clear value. Target early adopters include teleradiology groups handling large overnight or overflow volumes, outpatient imaging centers with high CT and MRI throughput, and regional hospital networks seeking to standardize QA and triage protocols.

[441]The primary integration pathway is through the RadTensor gateway, deployed alongside existing PACS and enterprise imaging systems. Early partnerships with PACS vendors or integration firms can accelerate deployment. RadTensor is positioned as an overlay that reduces AI integration complexity and cost, rather than as a replacement for existing systems.

[442]Incentives for early participation include preferential pricing, increased reward shares for early data contributors, and opportunities to participate in a clinical advisory council that informs task definitions, evaluation criteria, and roadmap priorities.

[443]Over time, RadTensor can expand regionally and vertically -- adding support for additional modalities, body regions, and task types, as well as deeper integration with reporting workflows and reimbursement processes. The core messaging remains consistent: RadTensor offers a vendor-neutral, compliant, usage-based AI imaging substrate that allows institutions to benefit from a competitive marketplace without locking into a single vendor.
