For efficient storing of medical motion images such as digital cine angiography, optimized compression ratio for motion image and efficient mass storage media is required. We have many selections to compressing motion image. MPEG-2 is one of de facto standard in motion image compression techniques. In order to find out optimized compression ratio using MPEG-2, both subjective evaluation and objective evaluation were carried out. These evaluation methods are based on severity decision of vessel stenosis for coronary vessel. From these results, we found optimized compression ratio using MPEG-2 is 1:80. In case of employing DVD-RAM media as storage media of medical motion images, the cost for storage is slightly more expensive than in case of employing CD-R media.
