The Department of Veterans Affairs requires an enterprise-wide Patient Radiation Dose Tracking system and support services to enhance safety, compliance, and care quality across its health network. The system must aggregate dose data from all imaging modalities, perform complex dose calculations, and generate customizable reports at local, regional, and national levels. It must be DICOM and HL7 compliant and integrate with existing VistA, Oracle Health Millennium, and various site-specific RIS and PACS systems. The system will be deployed to 135 VA facilities nationwide.
