Description

img2dcm has the ability to convert 12-bit (extended sequential) JPEG images to DICOM. Unfortunately, the tool in this case sets BitsAllocated=12 (which is not permitted in DICOM). BitsAllocated should be set to 16 in this case. Attached a sample JPEG image (from the IHE Connectathon 2019) and the result of the conversion to DICOM with DCMTK 3.6.4
