Compression can be applied not only to raw data transmission, but also to raw data storage. Currently, only reconstructed images are stored in PACS (picture archiving and communication system). This does not allow the flexibility to reconstruct different slices or do planar reformats since the original raw data is discarded. If we are able to compress the sinogram data with a tolerable amount of loss in the reconstructed image quality, we can store the raw data and then reconstruct desired images in the future.
