Background and Identification
A computed tomography or CT scan is a type of medical imaging that uses “a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body., “ according to Mayo Clinic. They also provide more detailed information than a regular x-ray.
The way a CT scan works is the patient lies on a bed that moves slowly through a donut shaped structure called a gantry, and the x-ray tube rotates around the patient, “shooting narrow beams of x-rays through the body.” (NIH) This image is picked up by digital x-ray detectors and then transmitted to a computer.
CT scans are used for a variety of imaging and are particularly useful for screening complex fractures. They can also be used for possible tumors or lesions within the abdomen or injuries, tumors, clots leading to stroke, hemorrhage, and other conditions related to the brain.
