Description

technical field [0001] The invention relates to the related technical field of medical devices, in particular to a headrest for cranial CT angiography examination. Background technique [0002] CT angiography (CTA, CT angiography) is a combination of CT enhancement technology and thin-slice, large-scale, and fast scanning technology. Through reasonable post-processing, it can clearly display the details of blood vessels in various parts of the body. It is non-invasive and easy to operate, and is of great value for vascular variation, vascular diseases, and displaying the relationship between lesions and blood vessels. [0003] In medicine, it is also called non-invasive angiography (CT angiography or CTA for short). Angiography is an interventional detection method. The contrast agent is injected into the blood vessel. This feature is used to diagnose vascular lesions through the image displayed by the contrast agent under X-ray.

Problems solved by technology

However, when actually doing this examination, the patient is prone to nervousness. If the head is not fixed well, there will be incomplete blood vessel examination or confusion and cannot cooperate with the examination, resulting in failure of the examination and affecting the examination results.

At present, the structure of the headrest for secret CT angiography examination in the prior art is complex, inconvenient to use, and cannot be fixed well in all directions. Common designs can be found in Chinese patents 201420466796.5, 201822240852.4, 201821604116.6, 201920014913.7, etc.
