A headrest for pet/ct scanning table

Abstract

The invention relates to a head support for a PET / CT (positron emission computed tomography) scanning bed. The head support comprises a head support body which is arranged on the scanning bed and comprises a bracket, wherein the bracket comprises a positioning plate connected with the scanning bed by virtue of a locking device, a head support plate which forms an upward angle with the positioning plate and two arm support plates; the two arm support plates are positioned on two sides of the head support plate and form upward angles with the head support plate; the outer sides of the head support plate and the arm support plates are wrapped with an integrally-molded head pillow. The relative positions of the head support and the scaning bed are defined, so that the influence of the abnormal status of a patient head is reduced, the image scanning quality is improved, the body posture requirements of the patient during PET / CT scanning are met, an included angle between the EML of the patient and the horizontal surface of the scanning bed is within a range of 90+ / -5 degrees, so that relatively clear brain tissue structures can be obtained in scanned images, especially the display of a subtentorial fourth ventricle and a supratentorial basal ganglia is favorable; meanwhile, both arms of the patient are effectively supported, and the comfort degree is increased.

Description

technical field [0001] The invention belongs to the technical field of instruments used for radiation diagnosis, such as instruments combined with radiotherapy equipment, and particularly relates to a method for stably supporting and fixing the patient's head during the medical imaging process, so that the patient's ear brow line (EML ) Headrests for PET / CT scanning beds with an angle between 90°±5° and the horizontal plane of the hospital bed. Background technique [0002] PET / CT (Positron Emission Computed Tomography) is a nuclear medical imaging device, which uses positron technology and human molecular information to simultaneously obtain the functional metabolism of the lesion and the positioning information of the precise anatomical structure, which is helpful for guidance It plays an important role in the diagnosis and treatment of tumors, heart and brain diseases. [0003] When using PET / CT to scan a patient, the patient needs to lie supine on the diagnosis bed / scan...

Problems solved by technology

[0004] The technical problem solved by the present invention is that in the prior art, most of the PET / CT scanning process needs to last 10 to 30 minutes, and the head, neck, and arms lack strong support and support, which makes it difficult for patients to Keep this posture until the end of the scan, and the patient is prone to move due to discomfort during the scan, and it cannot be guaranteed that when the brow line is used as the scan baseline, this line is basically perpendicular to the horizontal plane of the diagnostic bed / scanning bed, which will cause artifacts in the scanned image and affect the doctor The problem of normal diagnosis, and then provides a headrest for PET / CT scanning table with an optimized structure
