Development of a Multileaf Collimator for Proton Radiotherapy
Abstract
This report describes the second year of a project to design and construct multileaf collimators (MLC) to be used in proton radiotherapy, and the first year of the project to develop scanned beam technology for proton radiotherapy. This research project is a joint collaborative effort between the University of Pennsylvania (HUP) and the Walter Reed Army Medical Center (WRAMC) and is part of a larger project to build a state-of-the-art proton radiotherapy facility in Philadelphia in collaboration with the Children s Hospital of Philadelphia (CHOP). The accomplishments during the past year of the project are described in this report. (1) We developed software to read in DICOM-RT datasets and convert them to the GEANT4 geometry structure so we can calculate dose and display DVHs on CT data, (2) We incorporated a realistic proton nozzle into the GEANT4 Monte Carlo, (3) We started the study of spot-scanning optimization and have implemented two algorithms so far, and (4) The WRAMC group has started studying how heterogeneities affect the dose distribution in proton therapy.
