The introduction of PACS developed in our department of radiology and evaluation of the system were made. As a result, the following could be observed. 1) Image transfer by PACS proved to be more precise than either man or airshooter ; capable of saving power as well as time. 2) A great deal of time and manpower for the image examination could be saved. 3) Although communication now has to be faster, it is thought that the software will make up for this. 4) Many points were noted in the image-inputting system. 5) CRT reading was fully possible, dependent on the image processing method. In conclusion, PACS has numerous merits such as saving in power, time and space in image transfer, keeping as well as many others. However, image reading and calling have many problems in terms of both software and hardwares, making it necessary for both radiologists and radiological technologist to cooperate in preparing spot-matched images.
