DICOMweb

DICOMweb refers to a suite of RESTful web services built on the DICOM (Digital Imaging and Communications in Medicine) standard. It enables access to medical images and related data using standard web technologies and protocols such as HTTP, HTTPS, and JSON. DICOMweb aims to improve interoperability and facilitate easier integration of medical imaging into various healthcare IT systems and applications.

Specifically, DICOMweb defines several key services:

• WADO-RS (Web Access to DICOM Persistent Objects): Provides a method for retrieving DICOM instances (images, reports, etc.) stored in a DICOM repository using HTTP GET requests. It acts as a read-only access mechanism to existing DICOM objects.

• QIDO-RS (Query based on ID for DICOM Objects): Allows querying of DICOM objects based on identifiers and other attributes. This service supports searching for specific studies, series, or instances based on metadata.

• STOW-RS (Storage of DICOM Objects): Enables the storage of DICOM objects to a DICOM repository using HTTP POST requests. This service allows for uploading and storing new medical images.

• UPS-RS (Unified Procedure Step - Real-time Subscription): Facilitates communication and coordination of imaging workflows by enabling real-time updates on the status of procedure steps. It supports notifications regarding the progress and completion of various stages within an imaging procedure.

DICOMweb differs from traditional DICOM network communication (using DICOM C-MOVE, C-FIND, C-STORE) by utilizing web-friendly technologies, making it easier to integrate with web-based applications, mobile devices, and cloud platforms. It leverages standard web security mechanisms and is designed for scalability and accessibility across diverse network environments. This technology allows for improved data sharing, collaboration, and remote access to medical imaging information.
