Dr. Steven Bartolac completed his graduate studies in medical physics at the University of Toronto, followed by a residency in radiation oncology physics at the same institution.  His Master’s dissertation investigated the consequences of inherent data insufficiencies during typical cone-beam CT acquisition geometries.  During his PhD work, he investigated the application of spatial fluence modulation, akin to that employed in IMRT, to CT applications for optimizing both noise and imaging dose objectives during patient image acquisition.   His current research interests include CT protocol optimization for radiotherapy and exploring novel techniques and applications for orthovoltage treatments.
