Here, the medical diagnostic device includes an X-ray detector that captures an object to be photographed by X-rays emitted from an X-ray tube, and such an X-ray detector is commonly referred to as an 'X-ray detector (DR)'.

In the case of such an X-ray medical diagnostic device, the position of the animal or patient on the table must be changed when angle imaging is required depending on the examination area of the animal or patient.
