DICOM conformance

Most of the DICOM standard describes optional features. This page states which features of the DICOM standard (2018c version) our plugin implements. This is not a fully conformance statement, but will help customers to write conformance statements for applications that use DeCaMino.

Supported roles

  • Verification SCU and SCP
  • Storage SCU and SCP
  • Storage Commitment SCU and SCP
  • File-Set Reader and Creator
  • Query/Retrieve SCU and SCP
  • Basic Worklist Management SCU and SCP
  • Hanging Protocol Query/Retrieve SCU and SCP

As a Verification SCU, the plugin can send echo requests to remote application entities. When the application must accept remote associations for any other network service, the plugin answers echo requests as a Verification SCP.

As a Storage SCP, File Reader and Query/Retrieve SCU, the plugin can receive or read any storage SOP class instance. However, by default, as a Storage SCP or Query/Retrieve SCU, it only accepts to receive instances of one of the standard storage service classes for composite objects.

As a Storage SCU and a File Creator, the plugin may send or write any object. Fully conform instances of Multiframe Secondary Capture storage SOP classes can be automatically created by the plugin without requiring the user to provide all data elements.

As a Storage Commitment SCU/SCP, the plugin may send/receive storage commitment requests for any SOP Class. It may receive/send results in SCU or SCP-initiated associations, without limit on the time between the request and the result. Only the Push Model is supported. The retired Pull Model is not supported.

As a Query/Retrieve SCU, in addition to the storage SOP classes, the plugin supports the Find, Get and Move SOP classes for all three standard information models: patient root, study root and patient/study only.

As a Query/Retrieve SCP, the plugin supports any storage SOP classes. It may support the Find, Get and Move SOP classes for any information model. The application author must provide the implementation of the matching process for the needed information models.

As a Hanging Protocol Query/Retrieve SCU, the plugin supports the Hanging Protocol storage and the Find and Move SOP classes.

As a Hanging Procol Query/Retrieve SCP, the plugin supports the Hanging Protocol storage and the Find and Move SOP classes. The application author must provide the implementation of the matching process.

As a Basic Worklist Management SCU, the plugin supports the Find SOP classes for both standard information models: modality worklist and general purpose.

As a Basic Worklist Management SCP, the plugin may support the Find SOP classes for any information model. The application author must provide the implementation of the matching process for the needed information models.

Supported transfer syntaxes

The following table lists all transfer syntaxes DeCaMino knows about and thus can read, write or transfer. However, the ability to decode the pixel data to Java images or encode the pixel data from Java images is not available for all of these transfer syntaxes, as shown in the last 2 columns. The syntaxes with italicized names are retired from DICOM 2018c.

  • When sending through a Storage SCU (C-STORE service) or Query/Retrieve SCP (C-GET service), the default list of proposed transfer syntaxes is conservative:

    This list is also the list of transfer syntaxes claimed to be supported for storage SOP classes containing pixel data when associating with the Query/Retrieve SCU to a peer SCP, if C-GET is used during the association. This list is customizable in the case of the Storage SCP (but not in the case of the Query/Retrieve SCU as of DeCaMino 2.11).
