A high precise manufacturing system (Flexible Manufacturing System) has been developed to produce a compensator and a patient collimator for heavy- ion radiotherapy. The average machining error for compensator and patient collimator were + /- 100m and + /-504m r espectively. CAD data are based on CT scans which contain detailed information on patient co n tours and inhomogeneities.
However there are several problems remaining among which is the needed time from
