Computed tomography (CT) is a medical imaging technique that uses X-rays to create detailed cross-sectional images of the body. It combines multiple X-ray images taken from different angles and processes them using a computer to produce clear, 3D representations of internal structures. CT scans are commonly used to diagnose various conditions, including injuries, tumors, and infections. They provide valuable information for doctors, helping them to plan treatments and monitor the effectiveness of therapies. The procedure is quick and non-invasive, making it a widely used tool in modern medicine.
