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 a comprehensive view of internal structures, such as organs and tissues. CT scans are commonly used for diagnosing various conditions, including injuries, tumors, and infections. The images generated can help doctors assess the severity of a problem and plan appropriate treatments. This non-invasive procedure is quick and typically painless, making it a valuable tool in modern medicine.
