A branch of computer science that deals with the theory and techniques of computer image synthesis. Computers produce images by analyzing a collection of dots, or pixels (picture elements). Computer graphics is a mature discipline with a growing range of applications. It is used to enhance the transfer and understanding of information in science, engineering, medicine, education, and business by facilitating the generation, production, and display of synthetic images of natural objects with authentic realism almost indistinguishable from photographs. Computer graphics facilitates the production of images that range in complexity from simple line drawings to three-dimensional reconstructions of data obtained from computerized axial tomography (CAT) scans in medical applications. Images of three-dimensional anatomical surfaces can be constructed from the two-dimensional slices generated by computerized tomography or magnetic resonance imaging. These images help physicians to understand the complex anatomy present in the slices, and to evaluate and plan the treatment and even surgery of complex anatomical abnormalities (Fig. 1).
