What Is Computed Tomography?

Computed tomography (CT) is a diagnostic procedure that uses specialized X-ray equipment to obtain cross-sectional pictures of the body. The CT computer displays these pictures as detailed images of organs , bones, and other tissues. This procedure is also called CT scanning, computerized tomography, or computerized axial tomography (CAT). The picture below shows a longitudinal-section of the torso

Micro CT

MicroCT scanners are used in biological and other basic research to investigate the anatomy of, amongst other things, experimental animals. Using non-invasive imaging techniques to analyse the response of experimental animals has enormous advantages to the investigator and, most of all, to the animal. For example, measurements of tissue development can be made without sacrificing the subject and without pain. Repeated measurements may thus be made over time in the same animal, providing more accurate information and requiring fewer animals.
