CT球管的故障有多种情况。例如灯丝坏、球管打火、热交换器坏等等。本文介绍一种检测球管灯丝损坏的方法。这种方法无需更改电路板(如模拟控制板及系统控制板)的结构,只需要一只坏球管(但要求球管的灯丝正常)。方法简单易行。 故障现象:机器正常扫描时突然中断,不能曝光,不能进行正常的CT扫描。这时,电子触摸屏(ELTP)显 There are many cases of failure of a CT tube. For example, bad filaments, fired tubes, bad heat exchangers, etc. This article describes a method to detect bulb filament damage. This method does not require changes to the structure of the circuit board (such as the analog control board and the system control board), but only one bad bulb (but the filament of the bulb is required). The method is simple and easy. Symptom: When the machine scans normally, it is interrupted suddenly and cannot be exposed. Normal CT scan cannot be performed. At this time, the electronic touch screen (ELTP) is displayed
