Computed Tomography (CT)
Computed tomography (CT) is the process of creating cross-sectional or, tomographic images, by using a complex method of combining many images. The images are taken at different angles while an X-ray source rotates around the body.
CT scans are usually carried out with a dedicated CT scanner, but, because the images they provide can be so useful, they are often integrated into other medical equipment, such as linear accelerators, and gamma cameras.
The photograph below shows the CT scanner used in the Radiotherapy Department. The Perspex object on the couch is used to test the accuracy of the patient alignment lasers.
