Abstract
The purpose of the study was to evaluate the effects of lossy compression on grayscale US images to determine how much compression can be applied, and still have the images be 'acceptable for diagnostic purposes'. The study considered how the acquisition technique (video frame-grabber vs. direct DICOM digital format from the scanner) influences how much compression can be applied. For DICOM digital images, the study considered the how text (that is burned into the image) affects the compressibility of the image. The lossy compression techniques that were considered include JPEG, Set Partitioning in Hierarchical Trees (SPIHT) Wavelet, and a Modified version of SPIHT Wavelet.
