Manage DICOM services

Configure your OptosAdvance server and the remote DICOM servers on the network. You can use several types of DICOM services:

• Local Application Entity Configuration  Refers to OptosAdvance. OptosAdvance is a Storage Service Class Provider that can receive patient studies from remote DICOM servers.
• Streaming Service  OptosAdvance DICOM Query/Retrieve Service Class User service, which incrementally retrieves DICOM data and loads it directly to the OptosAdvance viewer without caching in the file system.
• Repository  Refers to a data directory path which can be used to store imported DICOM data.
• Storage Service Class Providers  Remote DICOM servers that can receive patient studies from OptosAdvance.
• Storage Commitment Service Class Providers  Remote DICOM servers that support the DICOM storage commitment service. Used to confirm that data has been permanently stored by a server to ensure it is safe to delete the data locally.
• Query/Retrieve Service Class Providers  DICOM servers that OptosAdvance can query and retrieve patient studies from.
• Modality Worklist Service Class Providers  Facilitate the communication of patient and scheduled acquisition procedure information to imaging modalities.
• Detached Interpretation Management Service Class Providers   Provide detached reports and notifications associated with studies.
• Print Service Class Providers  Remote DICOM servers which support DICOM printing.
• RESTful Dicom Service Providers  Remote DICOM servers which support DICOM QIDO-RS, WADO-RS, and STOW-RS protocols.
