[0002] X-ray detectors are widely used in medical equipment. For example, DR flat-panel detectors use X-rays for chest X-rays and bone and joint imaging. For knee joint imaging, the patient's knee joint must be bent for imaging. When the patient lies on the radiographic bed, the knee is bent until the long axis of the calf is perpendicular to the film, and the film is aligned between the kneecap and the femoral malleolus. The CR angle is about 60 degrees, at which point the kneecap and tibial joint cavity are clearly visible.

[0003] However, when the legs are placed parallel to the DR flat-panel detector for shooting, it is difficult to keep the legs at the required angle due to the lack of a limiting device. At the same time, the placement of the DR flat-panel detector is not uniform, making it inconvenient to adjust the height of the DR flat-panel detector according to the actual situation of the patient's leg bones and joints for X-ray shooting.
