西门子SOMATOM DEFINITION系统是双源计算机断层成像系统(dual source computed tomography,DSCT),通过2个X射线源和2套探测器来采集CT图像。无论患者的自身状况和心率如何,该系统都能进行高质量检查,还能通过双源在不同能量下的数据采集,即2个X射线源以不同的能量设置来工作,DSCT拓展了新型临床应用的范围。现将我院DSCT机出现的2例故障及维修经验介绍如下。
The Siemens SOMATOM DEFINITION system is a dual source computed tomography (DSCT) system that acquires CT images using two X-ray sources and two detectors. The system is able to perform high-quality inspections regardless of patient’s condition and heart rate, but also through dual-source data acquisition with different energies, ie two X-ray sources with different energy settings. DSCT has expanded its new clinical The scope of application. Now our hospital DSCT machine 2 cases of failure and maintenance experience described below.
