An innovative tool for intraoperative electron beam radiotherapy simulation and planning: description and initial evaluation by radiation oncologists

The lack of specific treatment planning tools limits the spread of Intraoperative Electron Radiation Therapy. An innovative simulation and planning tool is presented. Applicator positioning, isodose curves, and doseevolume histograms can be estimated for previously segmented regions to treat/protect. Evaluation by three radiation oncologists on 15 patients showed high parameter agreement in nine cases, demonstrating the possibilities in cases involving different anatomical locations, and identifying the importance of specialized surgical input in the preplanning process.Supported by grants PI08/90473, IPT 300000 2010 3, ARTEMIS S2009/DPI 1802(CAM), TEC2010 21619 C04 01, PI09/90568, ERD Funds.Publicad
