[Three-dimensional irradiation planing].
A software for three-dimensional display of dose distributions in irradiation planning was developed which is based on the computed tomography (CT) data and dose matrices of the commercial irradiation planning system Mevaplan (Siemens). Isodoses with CT background can be reproduced in all planes lying in a normal position with respect to the CT plane and displayed perspectively in any combination. In order to achieve a better quantitative assessment of the dose distribution, an algorithm was introduced into Mevaplan allowing the calculation and display of dose-volume histograms and of the dose gradient.
