ＣＴ管球是成本最高和最易损耗的配件。为了提高ＣＴ管球寿命提出以下方法。1 管电流校准在不影响图像质量情况下应略低于标称值。不同Ｘ线管的代表容量是固定的 ,以ＭＲＣ2 0 1ＣＴ -ＲＯＴ5 0 0 2型管球为例 ,它的小焦点代表容量为 48ｋＷ ;大焦点代表容量为 110ｋＷ ,代表
CT tube ball is the most expensive and most lossy accessory. In order to improve the life of CT tubes, the following methods are proposed. 1 The tube current calibration should be slightly lower than the nominal value without affecting the image quality. The representative capacity of different X-ray tubes is fixed, taking MRC201CT-ROT50020 type tube as an example. Its small focal point represents a capacity of 48kW, and the large focal point represents a capacity of 110kW.
