Description
A DICOM image whose pixel data is compressed with JPEG 2000, used for CT, MRI, X-ray and other medical scans; many viewers that read plain DICOM cannot decode it.
The JPEG 2000 Code Stream (j2c) file format is a type of image file format that is part of the JPEG 2000 family of image standards. This format is specifically designed for encoding images in a highly efficient manner, allowing for both lossless (exact reproduction) and lossy (approximate) compression. The j2c format focuses on the core coding stream of JPEG 2000 images, representing the encoded image data without additional metadata or structure.
