Computed tomography (CT) scan is a diagnostic medical imaging technique that uses X-rays and advanced computer algorithms to produce detailed images of internal structures of the body. It is also known as a CT scan or a CAT scan (computed axial tomography).
During a CT scan, the patient lies on a table that moves through a large, doughnut-shaped machine that rotates around the body. As the machine rotates, it emits a series of X-ray beams from different angles. The X-ray beams are detected by sensors, and the information is processed by a computer to create detailed, cross-sectional images of the body.
CT scans can provide images of internal organs, bones, soft tissues, and blood vessels, and can be used to diagnose a wide range of conditions, such as cancer, bone fractures, internal bleeding, and blood clots. They are also used to guide minimally invasive procedures, such as biopsies and needle aspirations
