ABSTRACT
X-ray radiography and tomography imaging are basic instruments used in screening and diagnosing patients and taking further decisions. X-ray tomography is an X-ray procedure, which, based on a set of X-ray projections, produces cross-sectional views and three-dimensional (3D) images of internal organs and structures of the body using computer algorithms (see Section III, Chapter 32). The main advantage of X-ray tomography over the traditional two-dimensional (2D) medical radiography is the removal of the superposition of images of structures outside the area of interest. This results in better visualization of lesions, since they are in focus, which in conventional radiography may be hidden.
