摘要: Dose uniformity within the treatment volume for tangent breast irradiation can be significantly improved through dynamic compensating collimation using all four independent jaws to define a superposition of sequentially reduced Enhanced wedge fields. The enhanced angle is determined which optimizes dose in central axis transverse plane, then sequential reduction superior and inferior optimize sagittal uniformity. This technique could applied under computer control record verify system.
