컴퓨터 단층 촬영, commonly known as CT scan, 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. This technology is widely used for diagnosing various conditions, including tumors, internal injuries, and diseases. CT scans are particularly valuable because they provide more detailed information than standard X-rays, helping doctors make informed decisions about patient care and treatment options.
