Computed Tomography (CT) scanning is a medical imaging technique that uses X-rays and computer processing to create detailed, cross-sectional images of the body. During a CT scan, an X-ray machine rotates around the patient, taking multiple images from different angles. These images are then processed by a computer to create a 3D image of the body part being scanned. CT scans can be used to visualize internal structures, such as bones, organs, and blood vessels, with great detail and clarity. CT scanning is often used to diagnose and monitor a wide range of medical conditions, including cancer, heart disease, and traumatic injuries. CT scans are non-invasive and generally considered safe, although they do involve exposure to ionizing radiation, which can be a concern for some patients.
