Three-Dimensional Teletherapy Treatment Planning. The Technique, an Analysis of the Quantitative Use of Computed Tomography, and Models for Dose Computation of Clinical Photon- and Electron BEAMS

摘要

This thesis deals with physical/mathematical backgrounds of computerized teletherapy treatment planning. The subjects discussed in this thesis can be subdivided into three main categories: a) Three-dimensional treatment planning. A method is evaluated which can be used for the purpose of simulation and optimization of dose distributions in three dimensions. b) The use of Computed Tomography. The use of patient information obtained from Computed Tomography for the purpose of dose computations is evaluated. c) Dose computational models for photon- and electron beams. Models are evaluated which provide information regarding the way in which the radiation dose is distributed in the patient (viz. is absorbed and/or dispersed). 86 references, 85 figures, 9 tables.
