Computer X-Ray Diagnosis (CT SCAN).
CT Scan or Computer Tomography is a type of body scan using computer x-ray to detect abnormalities in a specific body area such as cancer detection in the abdomen cavity or a brain scan. The machine emits radiation from X-ray tubes to circle around the organ into the opposite detector and measure the amount of radiation which is absorbed through the patient’s body to evaluate the density of the diagnosed organ and interpret it into electrical signals which are then transformed into an image by the computer system. The information collected by the computer is analyzed and separated into thin, transverse images allowing the doctors to see internally into the structure and the abnormalities of the organ which are clearer than other types of generic X-Ray images. CT Scan images can be in 3D or other planes of images to allow a more accurate diagnosis.
