Today's medical routine inspections often use X-ray photography. X-ray machine photography mainly uses the adjustment of the light-shielding film to determine the size of the irradiation area, control the illumination range, and reduce the receiving dose of unnecessary parts. In the traditional design, a medical radiologist is needed. The shading adjustment is performed manually or semi-automatically, and the position and range of the desired illumination are selected by adjusting up and down and left and right.

At present, the technical radiologist or the nursing staff needs to use the naked eye to judge the shading adjustment by manual operation, so there is a problem that the operation simplicity is insufficient. Moreover, when the radiologist or nursing staff performs the adjustment operation, it often differs due to personal experience value, professionalism, habits, personal emotions, etc., resulting in the accuracy of each adjustment, the size of the irradiation range, and the illumination. Different areas and other issues. If the X-ray film with the wrong irradiation range or the irradiation area is photographed, in addition to the easy interpretation of the treatment by the naked eye, the possibility of misdiagnosis may be caused. It is also often because of the large operational error value that the chances of patients needing to retest are greatly improved. In addition, the radiologist's shooting time also takes more time due to the inconvenience of manually adjusting the shading film.
