Paper Abstract

The success of radiation therapy depends upon the correct diagnosis of disease and the accurate delivery of radiation dose to that disease. An important part of radiotherapy is treatment planning in which various possibilities for the type, energy, size, and orientation of therapy beams are considered to insure that the intended volume is adequately irradiated. Treatment planning requires that the shape, size and depth of tumors as well as radiation-sensitive tissues be accurately identified. Furthermore, any distortions to radiation dose distributions caused by the presence of tissue inhomogeneities should be corrected. This paper discusses how computed-tomography scanners may be utilized to advantage in radiotherapy. Major benefits of scanners are described and difficulties associated with using scanner images in radiotherapy treatment planning are indicated.
