In order to establish a fast and effective computerized networking system for digital transportation of diagnostic pathology images, applicability of Asynchronous Transfer Mode (ATM) networking was investigated. Networking connection with Power Macintosh G3 B/W (Mac OS J1-8.6) to ATM through a PCI bus ATM extension interface card iXMicro Lightning II-25/155 M was easier to establish than the system using Sun work station (Ultra A12-YBA1-1E-128AB-E) and SunATM-155/UTP5 Sbus Adapter 2.0 extension card, and is recommended for general use in ordinary pathological laboratories. Transportation of digital data by ATM network was very effective and much faster (maximum155Mbps) than ordinary Ethernet system (maximum 10Mbps). Entrance and capture of photomicroscopic images through digitalizing process using digital photo apparatus is, however, still one of the most difficult obstacles to overcome for establishing real-time dynamic visualization of diagnostic pathological images, because it is needed very powerful CPU and big random access memory (RAM) (probably more than several gigabytes), and many problems should be solved before establishing computerized network system for transportation of dynamic images for diagnostic pathology.

为了建立一个快速有效的计算机化病理诊断图像数字传输网络系统，研究了异步传输模式（ATM）网络的适用性。采用Power Macintosh G3 B/W（Mac OS J1-8.6）通过PCI总线ATM扩展接口卡iXMicro Lightning II-25/155 M与ATM建立网络连接比采用Sun工作站（Ultra A12-YBA 1 - 1 E-128 AB-E）和SunATM-155/UTP 5 Sbus Adapter 2.0扩展卡的系统更容易建立网络连接，建议在普通病理实验室普遍使用。ATM网络传输数字数据非常有效，比普通以太网系统（最高10 Mbps）快得多（最高155 Mbps）。然而，利用数码照相设备对显微图像进行数字化处理，需要高性能的CPU和大容量的随机存储器（RAM），这是建立病理诊断图像实时动态可视化的最大障碍之一（可能超过几千兆字节），在建立病理诊断动态图像传输的计算机网络系统之前，还有许多问题需要解决。
