AB - Currently, most medical images are stored and compressed in accordance with the DICOM(Digital Imaging Communication in Medical) standards. However, DICOM standards compress the image to the JPEG(Joint Photographic coding Experts Group) standards, which affects loss of image quality to take place in the ratio of compression rate. Due to this loss, images are abnormally displayed just as stairs or saws, which is called the Aliasing effect. The more the effect is, the more distortion of the shape is. The loss of images occurred in the process of compression is irrecoverable. Hence, the original file should be separately kept to have images recovered. However, in case of JPEG2K, the loss of images are recoverable. Thus, the original file doesn't have be kept. It is proposed in DICOM Working Group that JPEG2K is used as DICOM medical image compression standards. This paper deals with compressing raw files similar to real DICOM images into JPEG and JPEG2K. And then this paper compares compression ratio, image quality and lossless compression. In the process of compression and comparison, the AHP(Analytic Hierarchy Process) method is used to objectively quantify subjective evaluations. Also, reliability of subjective evaluations use a consistency index to verify. As a result, JPEG2K scored about 50% higher than JPEG and showed better image quality and lossless compression. As a result, JPEG2K scored about 50% higher than JPEG and showed better image quality and lossless compression.
