Computed tomography
Computed tomography uses conventional x-rays, a circular array of special detectors, advanced electronics and powerful computers to produce internal tissue pictures of the human body. X-ray beams originating from the scanner's x-ray tube go through the body and are picked up by the scan detectors. The detector array, located within the doughnut-shaped gantry of the CT scanner, rotates in a spiral motion around the patient. The energy picked up by the detectors is fed into a computer that generates the cross-sectional x-ray pictures.
Computed technology procedures include:
- pelvis
- spine
- myelogram
- head/neck
- chest
- extremities
- abdomen
- biopsies
