Abstract
An irregular body surface in the radiation application area in therapeutic radiaction, e.g. in the head-throat region, leads to deviations of the dose homogeneity. To compensate for this, a lateral geometrically-corrected and radial absorption-corrected compensator made of Lipowitz metal (alloy 50% Bi, 26.7% Pb, 13.3% Sn and 10% Cd) is used. It exhibits higher absorption properties than tissue-equavalent materials. In order to produce the negative form for the compensator to be laterally reduced for divergence reasons, a device is used which scans the body section as well as leads a cutting device over a disc of finely porous polystyrene hard foam at the same time and forms to negative shape from its surface.
