Question

Describe how x-rays are used to generate pictures of the inside of your body.

Answer 1

Solution-

When imaging with X-rays, an X-ray beam produced by a so-called X-ray tube passes through the body. On it’s way through the body, parts of the energy of the X-ray beam are absorbed. This process is described as attenuation of the X-ray beam. On the opposite side of the body, detectors or a film capture the attenuated X-rays, resulting in a clinical image. In conventional radiography, one 2D image is produced. In Computed Tomography, the tube and the detector are both rotating around the body during the examination so that multiple images can be acquired, resulting in a 3D visualization.
