A conformance statement is a detailed description, in a specific format (as defined in Part 2 of DICOM) of the DICOM-specific features of a particular product.
Amongst other things, it describes:
- The SOP classes and transfer syntaxes supported
- What "real-world" activity triggers or is triggered by what network operations
- Character sets supported
Note that the requirement to relate to real-world activity makes it impossible to have a true DICOM conformance statement for a toolkit such as DicomObjects, and this is explained more fully on the DicomObjects_Conformance_Statement page.
