DIANA is a DICOM imaging informatics platform that can be attached to a PACS or image store such as Orthanc to support data analysis and archiving.
It supports a range of tasks from high-resolution image archival to cohort discovery to radiation dose monitoring. It provides DICOM services, image data indexing, REST endpoints for scripting, and user access control through an amalgamation of free and free and open source (FOSS) systems.
DIANA is written in Python and has API and CLI interfaces.
