探测器是CT机的重要部件之一。它在整机中担负X线穿过受检体后的剂量(模拟电信号)测量,并将其送入A/D转换电路成为数字信号,这一计算机接收原始数据的装置就是最终产生CT断层图像的基础。由于它结构复杂、装配工艺要求和工作电压较高,一旦发生故障往往只有通过更换新品来解决。但昂贵的更换代价常常困扰着医院,也使 Detector is one of the important components of CT machine. It carries the X-ray dose (analogue electrical signal) measured by the subject after passing through the subject and sends it to the A / D conversion circuit to be a digital signal. The device that receives the raw data from this computer is the CT slice The basis of the image. Because of its complex structure, assembly process requirements and higher operating voltage, once the failure is often only through the replacement of new products to solve. But expensive replacement costs often plague hospitals, too
