[3-D reconstruction in radiotherapy]

Abstract:
By means of computed tomography three dimensional compensators can be calculated as dose compensatory bodies for irradiation fields in radiotherapy. This is important especially for shell-type field irradiation and for bilateral total body irradiation. The dose homogeneity, attainable by compensators, is measured at a plexiglas phantom and represented and the use of compensators is described in practice.
