What is CT Scan?
Dr. Greene’s Answer:
A machine whirs in an arc around a patient, snapping a rapid-fire series of x-rays from different angles. These x-ray snapshots are combined by a computer to produce virtual cross-section images of the body. This is called a CT scan, which stands for computed tomography (computer-generated cross-sectional images).
