J2K in het kort
J2K
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.
DCM in het kort
DCM
DICOM grew out of the need to exchange imaging data across scanners, archives, and clinical systems without throwing away the surrounding context that makes a medical image usable in practice.

It is the correct target for diagnostic, archival, and interoperable clinical imaging systems.
What changes when converting J2K to DCM?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to DCM removes vector scaling.
What should I review after converting J2K to DCM?
