- CT scans
- Computerised axial tomography
- They produce high resolution images of soft and hard tissue
- Detectors form a two - dimensional slice through the body
- Multiple two dimensional CT scans can be put together to form a three - dimensional image
- An x-ray beam is fired through the body from an x-ray tube.
- This is then picked up by detectors on the opposite side.
- They use lots of x-rays to distinguish between tiny variations in tissue density
