Computed tomography, CT, also referred to as CAT scan, uses specialized x-ray equipment to obtain images of the body. Images from different angles are taken and then joined together to show a cross-section of body”’s tissues and organs.
The CT scanner emits and records x-ray beams for the duration of the scan. A special computer program is then used to form cross-sectional images, or slices of the area scanned. These slices are called tomograms. CT scans are used in the diagnosis and assessment of head injuries, stroke, clots in the lungs, appendicitis and many other conditions and diseases. Ct is also used in screening such as virtual colonoscopy and in radiotherapy treatment planning.
