Research

MR-Linac: Magnetic Interference
Real-time image-guided adaptive radiotherapy () is being explored at the Cross Cancer Institute by coupling a 0.2 T biplanar permanent-magnet MRI to a linear accelerator. My research involves using finite element analysis and other specialized software to study the effects of the magnetic interference from the MRI system on the production of an x-ray beam intended for use in radiotherapy. I am also investigating passive and active shielding methods to eliminate the effects of this magnetic interference.

EPID Modeling and Dosimetry
My research interests also include dosimetric of EPIDs for exit-beam and IMRT verification. Monte Carlo , with the addition of lag and ghosting correction are being investigated to improve the dosimetric response derived from the EPID.
