A Monte Carlo method for commissioning electron beams
Conference paper
Abstract
The dosimetric properties of electron beams produced by linear accelerators (linacs) exhibit small but significant variability between different manufacturers, mostly due to differences in the treatment head design [1, 2]. Even linacs produced by the same manufacturer can have different beam characteristics if a particular radiation oncology clinic requires electron beams that meet atypical specifications. For these reasons, institutions rely on linac-specific beam data that has been measured by a qualified medical physicist for treatment planning and beammonitor unit calculations.
