The core technology of the mobile C-arm X-ray machine is the C-arm structure, which can rotate and move around the body of the patient lying on the bed, so as to take complete images at multiple angles. This technology not only improves the clarity and resolution of the image, but also reduces the shooting time and alleviates the pain of the patient. In the related technology, in order to obtain a sufficiently clear image, when the bed enters between the C-arm, it is necessary to adjust the height of the bed or the C-arm so that the relative position of the bed and the C-arm is optimal, thereby avoiding blurred images due to improper angles, thereby ensuring the accuracy of the diagnosis results.
