Picture Archiving and Communication Systems (PACS) are getting more and more important for departments of radiology with the increasing spread of digital imaging methods. To determine the demands made on such systems, we calculated the digital image data volume for all examinations carried out in 1983 at the Department of Medical Radiology of the University of Tübingen. 20.37% of all examinations were performed with digitalised equipment. Plain radiography takes the lion's share among the total number of image data. If digitalisation is based on a spatial resolution of 8 Lp/mm, the share is 98.4% of the total image data volume of 7 123 GByte. This figure is far in excess of the estimates stated in literature. The possibilities of image data reduction and feasibility of a major PACS are discussed.
随着数字成像方法的日益普及，图像存档与通信系统（PACS）对放射科来说变得越来越重要。为了确定对这类系统的需求，我们计算了1983年图宾根大学医学放射科进行的所有检查的数字图像数据量。所有检查中有20.37%是使用数字化设备进行的。在图像数据总数中，普通X线摄影占了最大份额。如果数字化基于8线对/毫米的空间分辨率，那么在7123千兆字节的总图像数据量中，其份额为98.4%。这个数字远远超过了文献中所述的估计值。文中讨论了图像数据缩减的可能性以及大型PACS的可行性。
