Abstract

Precise knowledge and control of the amount of radiation delivered to specifically defined regions in the patient are essential for state-of-the-art radiotherapy (Stewart et al. 1978). Computerized tomography (CT) is an important component in precision dose delivery. The introduction of CT in the mid 1970’s and the concurrent availability of supermini-computers has resulted in a synergistic effect which is revolutionizing radiation therapy treatment planning. The combination of these two technologies offers the potential of greater precision in radiation therapy through improved three dimensional assessment of disease, localization of normal critical structures, inhomogeneity corrected dose calculations and precise field alignment. These improvements can result in more confident irradiation of the tumor with maximal sparing of adjacent normal structures. This chapter provides an overview of the capabilities of three dimensional treatment planning systems today and reports on current research and development in this area likely to be of clinical benefit in the near future. A number of recent references provide the interested reader with additional information (Wright and Boyer 1983; Goitein 1982a; Ling 1982; Cunningham et al. 1984).
