Problems solved by technology

Cranial CT examination is of great significance for the diagnosis of most diseases of the brain, skull, and scalp (including trauma, tumor, inflammation, vascular disease, poisoning, degenerative and metabolic diseases, etc., so when a patient has a tumor in the head, The tumor will cause the patient's brain to be asymmetrical, so two sets of fixed shells that are close to each other at the same time cannot clamp the patient's brain centrally, so the scope of application of the above document is small, and it needs to be improved
