What type of imaging technique does a CT scan primarily use?

A CT scan primarily uses X-rays to create detailed images of the body's internal structures. This imaging technique involves rotating X-ray beams around the patient, capturing multiple images from different angles. These images are then processed by a computer to generate cross-sectional views of the body, which allows for the visualization of organs, tissues, and even blood vessels.

In contrast, ultrasound uses sound waves to generate images, infrared radiation is associated with thermal imaging, and magnetic fields are the basis of MRI scans. Each of these methods serves different purposes and operates on different principles; however, the defining characteristic of CT imaging is its reliance on X-ray technology to produce high-resolution, three-dimensional images. This is essential for precise diagnosis and treatment planning in various medical conditions.
