JPEG2000, MCT, and JPIP have been added to DICOM for image compression and streaming. This presentation provides a demonstration of how these open standard-based technologies can be used together as a powerful platform for accessing large image volumes over bandwidth constrained networks. JPIP benchmarks and comparisons are also presented.

Growth of volumetric image data is making teleradiology very cumbersome as storage and networks are more rapidly consumed. J2K provides standards-based compression and random access to regions of interest and other image components. JPIP enables DICOM-compliant streaming of J2K data. MCT adds compression in the 3rd dimension and component collections, or subsets of images. These technologies allow a user to retrieve sub-resolutions in three dimensions, sub-qualities, and subsets of images from a volume. In practice, a 1000 slice, 1024x1024, 12 bpp volume is 1.95GB, but a user might only need a preview of 50 slices at ½ resolution and 10:1 quality. Using J2K, MCT, and JPIP to encode and transfer, the data retrieved is only 2.5MB, a 99.88% reduction in data transmitted. As the user reads the preview, more slice, resolution, and quality data is added in the background, significantly increasing user efficiency while decreasing network consumption and storage requirements.
