PACS IN OSAKA-UNIVERSITY HOSPITAL

To develop the hospital information system, the radiological informati on system, and the picture archiving and communication system for our new hospital, we analysed the data volume at each step of the flow in our present film-based system. After that, we used a small PACS, and i t indicated the problems in it. From the analysis of the data volume o f the film-based system, it was found out that digital data should be compressed, and prefetching techniques should be employed for digital PACS. Several types of display terminals had been proved to be necessa ry for different purposes. An RIS connection was thought to be obligat ory to avoid incorrect input of ID on the image. Image input terminals should have edit functions for easy recognition of the image informat ion. Taking account of these requirements for digital PACS, we are dev eloping an actual total PACS.
