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. This allows doctors to see bones, organs, and tissues in great detail. CT scans are commonly used to diagnose various conditions, including tumors, injuries, and infections. They are quick and non-invasive, making them a valuable tool in emergency medicine and routine health assessments. However, they do involve exposure to radiation, so their use is carefully considered by healthcare professionals.
