Description

Temporal bone styloid process and neck blood vessel CT examination action auxiliary device and method Technical Field The invention relates to the technical field of medical images, in particular to a temporal bone styloid process and neck blood vessel CT examination action auxiliary device and method. Background The temporal bone styloid process is a thin strip-shaped or cylindrical bone protuberance which is positioned at the joint of the temporal bone bottom surface and the mastoid region, the anatomical position of the temporal bone styloid process is fixed, and the temporal bone styloid process starts from the front inner side of the styloid process and the rear outer side of the jugular vein fossa, and the internal carotid artery and the internal jugular vein always run on the rear inner side region thereof. Clinical data indicate that about 4% of normal populations have stem mutations that are marked by excessive length, abnormal orientation, or morphological abnormalities, and such mutations may directly stress the internal carotid artery to cause arterial dissection, or block the internal jugular vein to cause reflux obstruction, severely affecting patient health. The neck 4DCT plus neck rotation test can dynamically observe the relation between the styloid process and the surrounding tissues, namely, a patient needs to inject CT contrast agent from the elbow vein, and the patient can do actions such as neck rotation, head lifting, head lowering and the like when the contrast agent passes through the carotid artery and the jugular vein. The peak time of the contrast agent can be maintained for about 10 seconds, the patient needs to complete the prescribed 6 actions within 10 seconds, each action needs to stay for 1 second for equipment scanning, the difficulty is high, and the probability of success of one examination is low. The neck 4DCT joint cervical rotation test can dynamically observe the relation between the styloid process and the surrounding vascular tissues, and has the core flow of injecting the contrast agent through the elbow vein of the patient, and leading the patient to finish the body position actions of left and right cervical rotation, head lifting, head lowering and the like by a doctor to synchronously perform CT scanning imaging in the concentration peak period of the contrast agent passing through the carotid artery and the jugular vein. However, this examination method has technical drawbacks in clinical practice that are difficult to overcome in the following three aspects: 1. The accuracy of the muscle contraction interference diagnosis is that when a patient actively applies force to complete the cervical rotation, neck muscle groups such as sternocleidomastoid muscle and the like can contract, and directly squeeze jugular veins, so that vein morphology and reflux state are distorted, and a doctor is interfered to judge pathological conditions. 2. The low matching degree of patients leads to high failure rate of examination, namely, the rotation neck and head elevation angles of partial patients can not reach the optimal body position required by diagnosis under the influence of the difference of the activity degrees of the neck of the individual, and meanwhile, hearing disorder patients or aged patients can not accurately respond to doctor passwords in the peak period of contrast agent, so that body position actions and scanning time are misplaced, and finally, the failure of examination is caused. 3. The scanning time and the motion state are difficult to match, the accurate synchronization difficulty of the CT machine exposure time and the patient neck rotation action is high, if the CT machine exposure time and the patient neck rotation action are exposed in the neck motion process, the image is easy to generate motion artifacts, the diagnosis requirement cannot be met, and the patient can bear unnecessary ionizing radiation after repeated scanning attempts, so that the health risk is increased. Aiming at the technical pain point, an examination auxiliary device and an examination auxiliary method which can accurately control the body position and optimize the scanning flow are needed to improve the diagnosis accuracy and the examination safety of the stem process related lesions. Disclosure of Invention Aiming at the defects of the prior art, the technical scheme adopted by the invention for solving the technical problems is that the CT examination action auxiliary device for the temporal bone styloid process and the neck blood vessel comprises a bottom plate, wherein the top of the bottom plate is fixedly connected with a containing unit, the top of the containing unit is fixedly connected with an action auxiliary unit, one end of the bottom plate is fixedly connected with a CT host, and the top of the CT host is fixedly connected with a CT frame; The action auxiliary unit comprises a first support plate, an arc groove is formed in the upper surface of the first su
