All kinds of medical images including kinematic and color images were found to efficiently store in a picture archiving and communication system(PACS) utilizing DICOM(digital image communication medicine) protocol, image data compression and high density storage media. JPEG lossy compression at 10:1 ratio is acceptable for the diagnosis of chest CT, head CT/MRI and liver CT/MRI.Image compression by Wavelet method can be accepted at higher compression ratio than JPEG method without significant degradation of image quality. Color crystal monitor and color CRT can be used for displaying images similarly to films in terms of image quality of CT and MRI. The radiology information system(RIS) to include both images and character data have been developed by employing DICOM protocol and World Wide Web(WWW). Those are connected to the hospital information system(HIS) and PACS through a local area network(LAN). Character data such as an examination order is transferred directly to the diagnostic modality through the LAN. Images and a diagnostic report are sent through the LAN similarly. It is possible to establish an information hemisphere in a hospital completely integrating HIS/RIS/PACS and diagnostic modalities.

利用DICOM（数字图像通信医学）协议、图像数据压缩和高密度存储介质，在图像存档和通信系统（PACS）中有效地存储了各种医学图像，包括运动图像和彩色图像。JPEG有损压缩10:1的比例可用于胸部CT、头部CT/MRI和肝脏CT/MRI的诊断。采用小波方法进行图像压缩可以获得比JPEG方法更高的压缩比，且图像质量没有明显下降。彩色晶体显示器和彩色CRT在CT和MRI的图像质量方面可以用来显示与胶片相似的图像。采用DICOM协议和万维网（WWW）开发了包含图像和字符数据的放射学信息系统（RIS）。它们通过局域网（LAN）连接到医院信息系统（HIS）和PACS。字符数据，如检查命令，通过局域网直接传送到诊断模式。图像和诊断报告同样通过局域网发送。可以在医院建立一个信息半球，完全整合HIS/RIS/PACS和诊断模式。
