故障现象:我院使用 EXEL2400elit 全身 CT 进行定位扫描时,发现图象右边出现一条约5mm 宽的黑色条状伪影,在做扫描时图象出现环状伪影。故障分析:在定位扫描时出现条状伪影,故此故障判断发生在 X 射线探测器部件伙食积分器部位,即数据采集系统。氙气探测器上共装有44块积分器,每块积分器有8个通道。2400elite 全身 CT 采用动态双焦点扫描技术,数据采集相当于704个通道。我们利用故障诊断程序对其进行诊断,提示地 Symptom: Our hospital using EXEL2400elit whole body CT scan positioning, we found a right side of the image appears about 5mm wide black bar artifacts, the ring appears in the image scanning artifacts. Failure Analysis: Strip scanning artifact appears, so the fault judgment occurs in the X-ray detector components diet integrator site, the data acquisition system. There are 44 integrators on the xenon detector and 8 channels on each integrator. 2400elite whole body CT using dynamic dual-focus scanning technology, data acquisition equivalent to 704 channels. We use the fault diagnosis program to diagnose it, suggesting that
