  • X-rays are invisible light. Therefore, the operator cannot know which part of the animal subject the X-rays penetrated until they view the X-ray image. Additionally, you cannot see the device inside the sealed under-table chamber. Therefore, the operator does not know the X-ray irradiation area in advance, and there is no means to simply set or modify the area to a desired subject area. Therefore, it is not possible to provide X-ray equipment that can be used in a veterinary hospital simply by placing the X-ray tube under the table. This is because it is difficult to obtain an accurate diagnostic image of the desired area, even though follow-up work such as veterinary diagnosis and treatment is possible only after obtaining an accurate diagnostic image of the part of the subject for which X-ray imaging is desired.

  • the operator's interest in obtaining X-ray images varies depending on the area of the animal subject being sought for diagnosis. Since the operator wishes to obtain images of a larger area in some cases and a narrower area in other cases, the light irradiation direction of the X-ray beam limiting guide lamp 97 must be able to be shifted. Additionally, the size of the X-ray beam limiting guide area 91 must also vary accordingly. Depending on the displacement of the X-ray beam limiting guide lamp 97, the rectangular coordinate value of the X-ray beam limiting guide area 91 displayed on the animal subject also changes.
