The fragmentation of medical imaging data across isolated Picture Archiving and Communication Systems (PACS) creates significant barriers to interoperability. This paper presents a functional Proof of Concept (PoC) for a decentralized, patient-centric medical image exchange system. By combining an Ethereum-based smart contract layer for access control and settlement with an off-chain Node.js "Worker" bridge, the system enables automated, peer-to-peer transfer of DICOM studies between disparate O...
