title: Clinical implementation of a computer controlled milling machine for compensating filter production.
abstract: The procedures required for the clinical implementation of a computer controlled milling machine for producing compensators for breast radiotherapy are described. Moulds are cut in a rigid polymer foam block and filled with stainless-steel granulate. Quality assurance procedures are described for ensuring that the compensators produced are consistent and accurate. Relative and absolute dosimetric measurements are presented showing that the compensators are accurate to better than 1% and demonstrate the technique to be clinically acceptable.
