CT (Computed Tomography), also known as a CAT (Computerized Axial Tomography) scan, is a type of medical imaging procedure that uses X-rays and computer technology to create detailed images of the body's internal structures.
During the procedure, the patient lies on a table that moves slowly through a ring-shaped machine that houses an X-ray tube and a detector. The X-ray tube rotates around the body and sends X-ray beams through the body at different angles. The detector measures the amount of radiation that passes through the body and creates multiple images of thin slices of the body's internal structures, such as the brain, lungs, liver, and bones.
The computer then combines the individual images to create a detailed, cross-sectional view of the body's internal structures. CT scans can reveal more detailed information about the body's internal structures than traditional X-rays, making them a valuable diagnostic tool for a wide range of medical conditions.
