Energy Modulated Electron Field Abutment Technique Improves Surface Dose and Provides Significant High Dose Volume Reduction

Traditional gapping techniques utilized in the abutment of electron fields lead to underdoses at the surface.  The penumbral characteristics of electron beams can lead simultaneously to the creation of high dose volumes in the gap between two electron fields. The size of the dose heterogeneity is energy dependent and increases with energy.  Conventional techniques to deal with the above dilemma have made use of extended distance, gaps, feathering, and devices.  Clinical implementation of an energy modulation technique is introduced which improves the dosimetry in the gap between megavoltage electron fields.
