A Monte Carlo study of a flattening filter-free linear accelerator verified with measurements.
A Monte Carlo model of an Elekta Precise linear accelerator has been built and verified by measured data for a 6 and 10 MV photon beam running with and without a flattening filter in the beam line. In this study the flattening filter was replaced with a 6 mm thick copper plate, provided by the linac vendor, in order to stabilize the beam. Several studies have shown that removal of the filter im...

PERSONNEL HAZARDS FROM MEDICAL ELECTRON ACCELERATOR PHOTONEUTRONS" R. C. McCall, T. M. Jenkins, R. A. Shore and P. D. LaRiviere+ Stanford Linear Accelerator Center, CA, U.S.A. and Varian Associates? INTRODUCTION For medical accelerators, neutron penetration through the room entry door is the major personnel hazard. Most therapy accelerator rooms are designed with at least a rudimentary maze to ...
متن کاملA Monte Carlo study on Photoneutron Spectrum around Elekta SL75/25 18 MV linear accelerator
Medical linear accelerators are one of the most widespread methods for cancer treatment. Despite their advantages, unwanted photoneutrons are produced by high energy linacs. This photoneutrons are as undesired doses to patients and a significant problem for radiation protection of the staffs and patients. Photoneutrons radiological risk must be evaluated because of their high LET and range.in o...

متن کاملMonte Carlo modeling of electron beams from a NEPTUN 10PC medical linear accelerator
Electron beam radiation therapy is used extensively for treating head and neck cancers to avoid the irradiation of the spinal cord. It is also used for treating chest wall malignancies to limit the irradiated volume of lungs. Calculating the dose distribution from an electron field is quite complicated because of the multiple scattering, especially in the presence of internal heterogeneities [1...
