While scanning the body with an X-ray beam, the data obtained by the detector is calculated by a computer, and the internal tissues of the body can be displayed in cross-sectional images in a short time (1 scan/1 second, reconstruction takes several seconds), and a 3D image can also be reconstructed. Moreover, it has a higher ability to distinguish human tissues than conventional X-ray examinations, making it one of the examination methods with high clinical diagnostic value. … *Some of the terminology that mentions "Hounsfield, GN" is listed below.
