Purpose : In a PACS(Picture Archiving Communications System) environment, which is a very important component in a digital medical environment, the compression of digital medical images is a necessary and effective feature. In a current system where JPEG is applied to the compression of medical images, this study is to examine effectiveness and suitability when the JPEG2000, a more advanced compression algorithm for still images, is applied to the compression of medical images. In this thesis, we attempt to address the compressibility for effective clinical usage when compressing medical images, applying the objectivization of clinical evaluation as a function of compressibility. In the experimental method, the compression was applied at a fixed rate using JPEG2000, and then the result was compared with compressed images by JPEG. Method : For the performance evaluation, we choose SNR(Signal to Noise Ratio) measurement of an objective evaluation of definition and analyze a subjective evaluation by the ROCCReceiver Operating Characteristic) method, The results of the experiment showed that in the case of JPEG2000 there is hardly any distortion of images, even at high compression ratio( 100:1)，while regarding noise, the SNR remains around about 40dB. which is also relatively high. Before reading by reference to evaluative materials concerning objective compressed images, it is impossible to apply high compression to images； however, after reading, this can be applied to images that have already existed for some time.
