Throughout history,a persistent goal of medicine has been the development of procedures for determining the basic cause of a patient’s distress.As a result,the search for tools capable of ‘‘looking into’’ the human organism with minimal harm to the patient has always been considered important.However,not until the later part of the twentieth century have devices capable of providing images of normal and diseased tissue within a patient’s body been available.Today,modern imaging devices,based on fundamental concepts in physical science (e.g.,x-ray and nuclear physics,optics,acoustics,etc.) and incorporating the latest innovations in computer technology and data processing techniques,have not only proved extremely useful in patient care,they have revolutionized health care.
