Examining CT scans. Radiographer examines a series of computed tomography (CT) scans on a lightbox. These scans show successive "slices" through the pelvis of a patient, with bone coloured white. CT images are obtained from a series of X-ray beams passed through the patient. The scanner is known as a tomograph (from a Greek word meaning slice). CT scans display good contrast between soft tissues in the body, differentiating between bone, fat, muscle and other tissues. CT scans are useful in locating tumours, blood clots, and diagnosing diseases.
