Background technique

Medical X-ray photography of cervical hyperextension and flexion is one of the main inspection methods to determine whether patients have vertebral instability. It judges whether the patient has spinal instability or spinal stenosis according to the degree of change in the position of adjacent vertebral bodies and the degree of compression on the intervertebral disc and spinal cord when the patient is in the extreme hyperextension and hyperflexion position. As shown in FIG. 1 , a conventional X-ray imaging apparatus includes a gantry 1 and an imaging screen 2 which is vertically slidable and provided on the gantry 1 . At present, when the patient's cervical spine hyperextension and flexion position is detected, the patient stands sideways in front of the camera screen 2, and the inspector instructs the patient to lower his head or raise his head as much as possible to achieve "hyperextension/hyperflexion". The flexion and extension angles cannot be quantified. The degree is greatly affected by the patient's subjective factors, and it is impossible to guarantee that the patient can truly achieve "hyperextension/hyperflexion", which will cause errors in diagnosis. At the same time, when the patient is in the "hyperextension/hyperflexion" state, it is difficult to maintain balance, and the body is more likely to shake, resulting in motion artifacts on the X-ray image, affecting the image quality, and even requiring re-photography, which increases the patient's ionizing radiation. radiation dose.
