About
Ellis Beld is a biomedical physicist whose research focuses on the intersection of magnetic resonance imaging (MRI) and radiation therapy, with a particular emphasis on MRI-guided brachytherapy for prostate cancer. His major contribution lies in quantifying the dosimetric impact of strong magnetic fields on high-dose-rate (HDR) brachytherapy treatments. In his most-cited work, a Monte Carlo study published in 2016, Beld systematically investigated how the Lorentz force from an MRI scanner’s magnetic field deflects secondary electrons from an Ir-192 source, altering dose distributions in surrounding tissue. This foundational research, which has garnered 11 citations, was critical to the development of a robotic MRI-guided HDR prostate brachytherapy system. By demonstrating that magnetic fields can cause clinically relevant dose perturbations, Beld’s work helped establish the need for magnetic-field-aware treatment planning algorithms. His research is essential reading for anyone working in MR-guided radiotherapy, bridging the gap between imaging physics and radiation oncology.
