[Automatic adaptation of stationary field dose distributions to the individual geometry of the patient. I: Calculation of dose distributions].

In radiotherapy approved standard irradiation techniques are available for almost all tumor localizations that has to be adapted to individual anatomic situations with the concrete particular case. A possibility is shown that allows an anatomic adaptation of four types of parameters for four coplanar irradiation fields in maximum with permissible expenditure of time. During the dose adaptation process the estimation of the separate dose distribution is done for the target area and for risk organs according to given criteria by an added measure function value that is calculated from measure function values for the areas to be estimated.
