I’m attempting to generate test DICOM data in all the supported transfer syntaxes that PACS systems could send to a service consuming DICOM:
Two of them are the Lossless and Lossy versions of the JPEG 2000 Part 2 Multicomponent Image Compression:
I’m using gdcmconv to convert datasets from one syntax to the next. Those transfer syntaxes are not listed in GDCM’s conformance summary (not even under the Unsupported section, I don’t know if this page is official or up to date):
Even if GDCM does not support JPEG Part 2 Multicomponent, I’d like to understand that format better. This is what came up with some Googling around:
- This wiki page from GDCM mentions its support as a potential Summer of Code project
- Those slides seem to associate Part 2 multicomponent with multi-frame / 3d images
- .jpx would be the extension for the Part 2 specifications
- it’s associated with ISO/IEC 15444-2
defines a set of lossless (bit-preserving) and lossy compression methods for coding continuous-tone, bi-level, grey-scale, colour digital still images, or multi-component images.
In conclusion: does anyone have experience with JPEG 2000 Part 2 encoding, and could clarify its use? What does it mean by multicomponent, and could it be used for single frame as well as multi frames images/dicom objects?
