What type of imaging technique uses X-ray beams in a circular motion?

The imaging technique that utilizes X-ray beams in a circular motion is computed tomography (CT). In this process, multiple X-ray images are taken from different angles around the body. The circular movement of the X-ray source, along with the rotating detector, allows for the collection of cross-sectional images, or slices, of the body. These slices can be compiled to create detailed three-dimensional images, providing a comprehensive view of the internal structures. This ability to visualize various layers of tissues makes computed tomography particularly useful for diagnosing a wide range of conditions, including tumors, internal bleeding, and complex fractures.

Other imaging techniques serve different purposes and utilize other methods. For instance, magnetic resonance imaging uses strong magnetic fields and radio waves rather than X-rays, while radiography refers to traditional X-ray imaging without circular motion or slice generation. Positron emission tomography involves radioactive substances to visualize metabolic processes, instead of using X-rays in a circular path.
