Lossless compresion of DICOM data with progresive transfer capabilities
Obrul, Denis ; Klajnšek, Gregor ; Žalik, Borut
Today, the exchange of medical images betwen various physicians is taken for granted. But it wasn't always so. Only two decades ago, exchange of such images was difficult at best. Unless medical ...institutions owned identical sets of imaging machines, sharing medical images electronicaly proved to be very limited. In this paper, we present the DICOM standard, which is one of the world's leading standards for medical information exchange, particulary the exchange of medical images. We continue our journey with the description of data compression algorithms. All the algorithms achive lossless compression rates, which are typicaly well over 65%. At the end, we present the application Dr. DICOM, which contains all the developed algorithms and procedures. Due to application's sucsesful compression rates, we have also developed a web page, with which we wish to present Dr. DICOM to a much broader audience. We firmly belive that the application has a high future-development potential and that it would contribute towards a better and more efficient long-term storage of medical data.
