30 3D absorbed dose reconstructed in the patient from EPID transit images for VMAT treatments on TrueBeam machine

Autor: Xavier Franceries, F. Younan, D. Franck, Isabelle Berry, J. Mazurier, A.R. Barbeiro

Publikováno v: Physica Medica. 56:18-19

Introduction Since the release of complexes techniques in external radiotherapy, the EPID (Electronic Portal Imaging Device) is more often used to perform patient quality assurance. The purpose of this work was to develop a back-projection algorithm

Autor: Francisco Javier García-Gómez, A. Vargas, Ana Ureba, A.R. Barbeiro, J.A. Baeza, E. Jimenez-Ortega, Amadeo Wals-Zurita, Antonio Leal

Publikováno v: Physica medica : PM : an international journal devoted to the applications of physics to medicine and biology : official journal of the Italian Association of Biomedical Physics (AIFB). 42

Purpose To develop a new optimization algorithm to carry out true dose painting by numbers (DPBN) planning based on full Monte Carlo (MC) calculation. Methods Four configurations with different clustering of the voxel values from PET data were propos
