TASSELLAZIONE DI IMMAGINI PER ACCESSO A COEFFICIENTE SPECIFICO DI REGIONE

摘要

A picture archiving and communication system includes an image data compression station which received image, data files and compresses the image data. The compression is performed via one or more optimal compression algorithms for subregions of the image data. Hybrid compressed data files are created including a descriptive header and the optimally compressed image data. Code identifying the selected algorithms is inserted into the hybrid files. A server receives and stores the hybrid files, and access the files upon demand for client stations, wherein the hybrid compressed files are decompressed for viewing of the encoded images. Rapid data exchange within the system are facilitated by the use of compressed data and by the availability of descriptive data from the header portions of the files.
