Monte Carlo based dose estimation in intraoperative radiotherapy

摘要

This work presents the application of an updated version of an existing Monte Carlo (MC) code for photon and electron transport to intraoperative radiotherapy (IORT) dose planning. The code has been optimized to provide an estimation of the dose delivered by the linear accelerator (LINAC) in very short time and has been incorporated as a submodule of an advanced IORT planning system under development, which will enable far more accurate pre-planning as well as the intraoperative treatment modifications considering actual information taken at the operating room (OR) during surgery, for instance with a mobile C-arm.
