DICOMweb is a term applied to the family of RESTful DICOM services defined for sending, retrieving and querying for medical images and related information.
The intent is to provide a light-weight mobile device and web browser friendly mechanism for accessing images, which can be implemented by developers who have minimal familiarity with the DICOM standard and which uses consumer application friendly mechanisms like http, JSON and media types (like "image/jpeg") to the maximum extent possible.
The standard is formally defined in DICOM PS3.18 Web Services.
The DICOMweb services are distinguished from other DICOM web services by the suffix "-RS", indicating their RESTful nature.
The family consists primarily of:
- WADO-RS for retrieval of DICOM PS3.10 files, meta data in XML or JSON forms, bulk data separated from the meta data and rendered consumer format images
- STOW-RS for storage (sending) of DICOM PS3.10 files or separated meta data and bulk data
- QIDO-RS for querying collections (databases, registries) of DICOM objects
A key feature of the WADO-RS services is the ability to retrieve entire studies and series rather than needing repeated request for individual instances.
Other services including support for work lists (UPS-RS) and retrieval of server capabilities.
