Auto-commissioning of a Monte Carlo electron beam model with application to photon MLC shaped electron fields. Physics in medicine and biology, 68(4) Institute of Physics Publishing IOP 10.1088/1361-6560/acb755
Objective. Presently electron beam treatments are delivered using dedicated applicators. An alternative is the usage of the already installed photon multileaf collimator (pMLC) enabling efficient electron treatments. Currently, the commissioning of b

Enabling non-isocentric dynamic trajectory radiotherapy by integration of dynamic table translations. Physics in medicine and biology, 67(17) Institute of Physics Publishing IOP 10.1088/1361-6560/ac840d
Objective. The purpose of this study is to develop a treatment planning process (TPP) for non-isocentric dynamic trajectory radiotherapy (DTRT) using dynamic gantry rotation, collimator rotation, table rotation, longitudinal, vertical and lateral tab
