What is the choice of high kV head-to-head shooting speed?

Medium-speed CaWO4 _ 4 sensitizer is selected for high kV header. According to relevant public information, the fixed kV mode is adopted for high kV photography, and the exposure latitude is increased. High-resolution medium-speed CaWO4 sensitizing film can ensure screen matching and good adhesion. High kV photography can reduce tube flow, reduce heat generated by X-ray tube, improve photo contrast and equipment efficiency, and prolong the life of X-ray tube.
