故障例1：GE－Sytec40001全身CT机．扫描时高压发生器内阳极侧有轻微的打火声,扫描图像中伴有伪形。据此现象分析故障应在高压发生器至X球管等部件中。经检查高压电缆线外观完好，无高压放电击穿产生的针眼等痕迹。拔掉高压发生器测正负高压电缆接头，手动冷高压吸光，而压发生 Fault Example 1: GE-Sytec40001 whole body CT machine. A slight sparking sound is generated on the anode side of the high voltage generator during scanning, accompanied by a false image in the scanned image. According to this phenomenon analysis should be high pressure generator to the X-tube and other components. After checking the appearance of high-voltage cable intact, no high-voltage discharge pinhole and other traces of the breakdown. Unplug the high-voltage generator to measure the negative high-voltage cable connector, manual cold high-pressure light absorption, and the pressure occurs
