Monte Carlo Simulation of the Electron Beams Produced by a Linear Accelerator for Intra- Operative Radiation Therapy
In this work, organized as a short review, we present some results obtained by applying the Monte Carlo techniques in the Intra-Operative Radiation Therapy (IORT). The electron beams generated by the NOVAC7 IORT accelerator have been simulated using BEAMnrc/EGSnrc Monte Carlo code, the dose distributions and water-to-air stopping power ratios being later calculated with the associated software ...
متن کاملSafety, effectiveness and economic evaluation of intra-operative radiation therapy: a systematic review
Background: Intra-operative radiation therapy (IORT) is the transfer of a single large radiation dose to the tumor bed during surgery with the final goal of improving regional tumor control. This study aimed to investigate the safety, effectiveness and economic evaluation of intra-operative radiation therapy. Methods : The scientific literature was searched in the main biomedical databases ...
متن کاملEvaluation of LiF:Mg,Ti (TLD-100) for Intraoperative Electron Radiation Therapy Quality Assurance
BACKGROUND Purpose of the present work was to investigate thermoluminescent dosimeters (TLDs) response to intraoperative electron radiation therapy (IOERT) beams. In an IOERT treatment, a large single radiation dose is delivered with a high dose-per-pulse electron beam (2-12 cGy/pulse) during surgery. To verify and to record the delivered dose, in vivo dosimetry is a mandatory procedure for qua...
متن کاملMonte Carlo Simulation of Electron Beams produced by LIAC Intraoperative Radiation Therapy Accelerator
Background: One of the main problems of dedicated IORT accelerators is to determine dosimetric characteristics of the electron beams. Monte Carlo simulation of IORT accelerator head and produced beam will be useful to improve the accuracy of beam dosimetry.Materials and Methods: Liac accelerator head was modeled using the BEAMnrcMonte Carlo simulation system. Phase-space files were generated at...
متن کاملAssessment of the effects of radiation type and energy on the calibration of TLD-100
Introduction: In radiation therapy, knowing the dose rates to healthy organs and tumors is beneficial, and thermoluminescent dosimeter (TLD) allows for this possibility. This study was aimed at determining the dose-response differences of TLDs in various types of radiation, energy levels, and dose rate calibrated with other types of radiation beams and energy and dose levels. Materials and Meth...
