WHAT IS AN CT SCAN?
Computerised Tomography (CT) is an x-ray examination performed with a computerised x-ray scanning machine. The CT scan looks at the body in cross section. To produce images, a narrow beam of x-rays is rotated around the part of your body to be examined. The x-ray beam is monitored and recorded by an array of sensitive detectors which channel the signals to a large computer within the scanner. The computer then generates a visible image of the cross section of the body region being examined.
