How it Works
During a CT scan, a thin beam of radiation is focused on the specific body part to be studied. The X-ray tube moves completely around this body part as the table moves the patient through the scanner. This creates multiple cross sectional images, which are sometimes compiled into 3-D images when necessary. Due to the precision of these exams, the patient must lie completely still.
The cross-sectional images are produced and manipulated with the aid of advanced computers to allow a thorough picture of the patient's anatomy.
