CT Scan (CAT Scan): Purpose, Procedure, Risks, Side

In computed tomography (CT), an x-ray tube moves around the body and continuously projects a thin fan of x-rays through the body. Electronic detectors opposite the tube continuously monitor the number of x-rays passing through the body and the angle at which the beam is being projected University Short Course Computed Tomography (CT) Course: Professional Certificate. Fee: R 8 000.00 Relevant fields of study: Health and Wellness. Offered by: Medical Imaging and Therapeutic Science In computed tomography, a scanner produces and records x-rays as it rotates around a person, who is moved through the scanner on a motorized table. On one side of the scanner is an x-ray tube, which produces x-rays, and on the other side is an x-ray detector Computed tomography doesn't allow information from irrelevant locations to even enter the acquired data. Several preprocessing steps are usually needed before the image reconstruction can take place. For instance, the logarithm must be taken of each x-ray measurement. This is because x-rays decrease in intensity exponentially as they pass.
