The field integrated dose modification (FIDM): three typical clinical applications of a new irradiation technique.
In addition to an earlier developed "compensator integrated modification technique", a method is derived which uses as basic principle the "field integrated dose modification" (FIDM) without need for computer tomographic data. The method enables the radiotherapist to introduce one or more volumes within which doses can be delivered which are different from the one in the main irradiation volume. The steps of practical preparation and clinical application are described in detail. The radiobiological aspects of FIDM, especially those in case of acceleration and hyperfractionation, are elucidated by discussing three typical examples.
