In FIG. 5, the X-ray tube 2 and the X-ray detector 3 are always arranged to face each other with the subject 1 in between, and the X-rays emitted from the X-ray tube 2 are partially absorbed by the human body. The rest reaches the X-ray detector 3 as transmitted X-rays and is detected to be projection data. The obtained projection data is sent from the data collecting unit 4 to the image reconstructing device, processed through a computer, displayed on an image display device, and stored in an image storage device.
In this case, a high voltage generator for generating X-rays or X
The X-ray tube 2, the X-ray detector 3, and the data acquisition unit 4 are built in the pedestal 5 shown in FIG. 6 and take an image of the subject 1 while rotating. Then, the subject 1 is placed on the bed 6 provided for accurately positioning the imaging position in the imaging region between the X-ray tube 2 and the X-ray detector 3 in the opening of the gantry 5. Lying on the board 7.

Conventionally, a frame such as the X-ray CT apparatus is constructed as shown in FIG. FIG. 7A is a front view of the gantry 5, and FIG. 7B is a side view thereof.
FIG. 7C is a diagram showing a state in which the front cover 8 of the gantry 5 is opened with respect to the scanner body 9 and flipped up. The scanner body 9 contains at least the X-ray tube 2, the X-ray detector 3, and the data acquisition unit 4, which are means for forming an image as described above. Further, the operation panel 10 is fixed to the front cover 8 in a non-detachable state, and when the front cover 8 is opened and flipped up as shown in FIG. 7C, the operation panel 10 also follows. I will end up. Therefore, since the operation panel 10 is located on the upper surface of the front cover 8, the height thereof becomes too high, and the operator 1 such as a service person during maintenance or a worker during testing / adjustment.
