Two basic types of image compression exist: lossy compression and lossless compression. IMPAX automatically performs lossless JPEG compression on almost all incoming images. Typically, IMPAX is also configured to create a lossless wavelet version which is used primarily for distribution over lower bandwidths.
IMPAX also supports lossy JPEG and lossy wavelet compression. Lossy compression increases the storage capacity and the number of images that can be stored in a cache or archive; however, lossy compression reduces image quality and is therefore, intended only for non-diagnostic purposes.
The configuration of lossy and lossless representations of an image allows IMPAX to address the requirements for various clinical workflows.
