A prototype high definition multi-leaf collimator system (HDI) has been developed and installed on the linear accelerator for use in conformal radiotherapy. The HDI technique utilizes the dynamic shift of the 3D-target volume to feather the multi-leaf collimator defined field edges. During each feathering, the leaf positions are adjusted according to the updated target image projected into the MLC plane. The purpose of this study is to demonstrate that this device can improve spatial resolution of a conformal radiation therapy treatment. The results of this study indicate that the HDI technique can be a useful tool for treating small, or highly irregular shaped targets, and for sparing adjacent critical structures for certain cases.
