What does CT mean

hello, CT (ComputedTomography) uses computer technology to reconstruct the tomographic image of the measured object to obtain a three-dimensional tomographic image. In this scanning mode, rays from a single axial plane penetrate the measured object, and according to the different absorption and transmittance of rays by different parts of the measured object, the transmitted rays are collected by a computer and imaged through three-dimensional reconstruction. Purpose of brain CT examination: cerebral hemorrhage, cerebral infarction, aneurysm, vascular malformation, various tumors, trauma, hemorrhage, fracture, congenital malformation, etc.

hello! CT examination is a kind of modern advanced medical scanning examination, which is mainly aimed at scanning the human brain. CT diagnosis is generally plain CT, enhanced CT and cisternography CT. It has high density resolution and can directly display organs and lesions that cannot be displayed by X-ray examination. Moreover, the examination is convenient, rapid and safe, and the examination can be successfully completed as long as the patient does not move, which overcomes the overlap of traditional X-ray plain images.

CT uses X-ray tomography, which is received by an electro-optical detector, and converts the signal into a digital input computer, and then the computer converts it into an image. Purpose of brain CT examination: epilepsy can be caused by many reasons, such as brain atrophy, brain hypoplasia or retardation, brain tumor, cerebral vascular malformation, cerebral infarction, hydrocephalus, brain malformation, encephalomalacia, brain calcification, high-density changes of unknown causes or properties, low-density changes and so on. If there are the above lesions in the brain, CT examination can find them. If the CT film shows normal, the existence of the above lesions can generally be ruled out.
