Method and system for reducing of dosing errors in the case of an optimized static intensity modulation

摘要

A process for the dosimeter installation - correction in a radiation therapy device, wherein thean initial set of segments for the radiation emission (1002) is fixed, whereby at the same time the number of monitor units is determined for each segment;a plurality of correction factors, which are linked with each of the segments is determined (1004),an error for each of the segments is determined (1008) based on a plurality of correction factors,one of the segments as a maximum average error comprising, is determined;a correction factor for the segment is adjusted, in which the presence of (1018) of the maximum average error has been recognized andthe discovery - and adjusting steps are repeated until the determined error (1014) for each of the segments a predetermined condition is satisfied.
