[0002] Spinal angiography is a medical diagnostic technique, mainly used for the diagnosis of spinal cord tumors, spinal cord vascular diseases, etc. It involves injecting contrast agents into the patient's spinal cord blood supply artery through an angiography catheter, so that the spinal cord blood vessels can be visualized under X-rays to understand the morphology of the spinal cord blood vessels themselves, lesions, and the nature and extent of the lesions.
[0003] When performing spinal angiography on patients clinically, it is necessary to determine the position of the vertebra where the lesion is located. Since the human body has 24 vertebrae, but only 6-7 vertebrae can be seen on the screen during angiography, the traditional method requires doctors to judge the number of columns based on experience.

Secondly, the angiography time is prolonged, the radiation dose is increased, and excessive damage is caused to the health of patients and doctors. Currently, lead ruler tools are often used to pad under the patient's body to provide a vertebral positioning reference during angiography. However, placing the tool under the patient's body will cause discomfort to the patient, and it is difficult to adjust the positioning point according to the patient's body shape and lying position.
