At present, it is widely used in the diagnosis of clinical diseases, and it is an indispensable inspection method for some lesions.

There is a strong magnetic field inside the MRI examination room for medical use. Therefore, equipment containing metal parts such as stretchers, wheelchairs, surgical carts, and hospital beds commonly used by patients cannot be brought into the examination room. Critically ill patients entering and exiting the examination room must be carried or carried by medical staff or family members. This not only increases pain and even aggravates the condition of patients with severe fractures and craniocerebral injuries; it also increases the labor intensity of family members and medical staff, and brings great inconvenience to medical examinations.

At the same time, because the MRI examination requires the patient to have a high degree of cooperation, the shaking of the head and limbs can cause serious movement artifacts and the examination cannot be completed. However, the high-field-strength MRI of the MRI examination has relatively high noise, generally at 65~ Between 95 decibels, individual sequences can reach 100 decibels of noise. Although it is within the safe range, it is still unbearable. A small number of subjects will experience symptoms such as temporary tinnitus and temporary hearing loss. Therefore, appropriate auxiliary fixation is needed for some patients with impaired self-control ability or patients with forced head position. At present, the sponge pad randomly delivered by the MRI machine is mostly used for filling, and the space filling is not satisfactory enough to effectively prevent the shaking of the patient's head and neck.
