1、首先对曝光时间控制的精度工频X射线机的曝光控制精度根据整流方式不同而差别很大。高频透视x光机发生器采用的是电压预置，反馈调节的方法，控制精度高。这样，可以大大减少X射线光柱束中的软射线成扥，降低病人的辐射剂量，太高曝光重复性，从而提高X射线照片质量。其实，也是提高了X射线的输出效率。

1. First of all, the accuracy of the exposure control of the exposure time control frequency X ray machine is very different according to the different rectifying methods. The generator of high frequency X-ray X-ray machine adopts the method of voltage preset and feedback adjustment, and the precision of control is high. In this way, can greatly reduce the soft X-ray X ray beam in the beam to reduce the radiation dose of patients with Orlando, too, the exposure to high repeatability, so as to improve the quality of radiographs X. In fact, it also improves the output efficiency of X rays.

2、进行观察，结构简单由于中高频X射线发生器的KV和MA值采用了纯电子方式分别预置、反馈调节的方式，没有任何机械旋钮和开关，省去了KV补偿电路和空间电荷补偿电路

2, observe, the structure is simple, because the KV and MA values of the high and medium frequency X ray generator are pre arranged and feedback regulated in pure electronic way, without any mechanical knobs and switches, which eliminates the KV compensation circuit and the space charge compensation circuit.

3、其次注意没有机械接点和旋钮，不仅响应速度快，输出参数精度高，而且可以在曝光期间对KV和MA进行调整；

3, secondly, there is no mechanical contact and knob, not only fast response speed, high precision of output parameters, but also can be adjusted to KV and MA during exposure.

4、同时需要注意采用了储能元件，对电源的供电要求大大降低，甚至可以利用直流电直接供电（大型工频X射线机往往需要专线供电）

4, at the same time, we need to pay attention to the use of energy storage components, which greatly reduce the power supply requirements, and even use direct current to directly supply power. Large power frequency X ray machines often need special line power supply.

5、由于频率高，根据变压器方程，可以使得高压变压器的体积大大缩小，便于大功率（大容量）X射线机发生器的小型化；

5, because of the high frequency, according to the transformer equation, the volume of the high-voltage transformer can be greatly reduced, which is convenient for the miniaturization of the high-power (large capacity) X ray generator.

6、最后由于变压器体积小，不仅节省了制作成本，而且减少了高压发生器的铜耗与铁耗。

6. In the end, because of the small size of the transformer, it not only saves the production cost, but also reduces the copper consumption and iron consumption of the high voltage generator.
