How Does A CT Scan Work? (Computed Tomography Scan)
A CT scan is an x-ray procedure that creates cross-sectional images with the help of computer processing. CT images are more detailed than conventional x-ray images and can reveal bones as well as soft tissue and organs. A conventional x-ray uses a fixed tube that sends x-rays in only one direction. While a CT scanner uses the motorized x-ray source that shoots narrow beams of x-rays as it rotates around the patient. There are special digital x-ray detectors located directly opposite the x-ray source. As the x-ray passes through the patient they are picked up by the detectors and transmitted to a computer. Image slices can either be displayed individually in two-dimensional form or stacked together to generate a three-dimensional image that can reveal abnormal structures to help the physician plan and monitor treatments.
