[0035] Specifically, by utilizing the partially overlapping functions between CT / DR scanning devices, the two scanning methods are integrated and optimized to reduce the costs of equipment purchase, installation, and operation. At the same time, the two systems can operate independently without interfering with each other, thereby maximizing the utilization rate of the equipment and forming a scanning device that takes into account both CT / DR scanning functions.

[0036] According to the embodiment of the utility model, the detector module 21 includes a mounting seat and a slide rail 215 arranged inside the mounting seat. The top of the slide rail 215 is connected with a flat-panel detector 212 , and the flat-panel detector 212 can slide along the slide rail 215 .
