ＳＯＭＡＴＯＭ—ＡＲ．Ｔ是德国西门子公司于一九九一年向我国推出的新一代全身ＣＴ。该机计算机集成度高，体积小；软件丰富，便于更新换代；扇形束旋转式高速扫描。图像清晰。我院ＣＴ机工作两年半以来，出现过几次软件故障，主要原因是机器运行过程中突然停电导致软件损坏 SOMATOM-AR. T is a new generation of whole body CT introduced by Germany’s Siemens to China in 1991. The computer has a high degree of integration and small size; it is rich in software and easy to update; fan beam rotating high-speed scanning. The image is clear. Two and a half years since the CT machine in our hospital had experienced several software failures. The main reason was that the sudden power failure during the operation of the machine resulted in software damage.
