Accurate Dosimetry for Ocular Brachytherapy: Measurement, Delivery Uncertainty, and Dose Calculation Studies
DownloadFall 2017
Ocular brachytherapy has been found to be an excellent alternative for the treatment of ocular melanomas compared to the predominantly used treatment prior to the 1980s of enucleation. Tumour control rates are generally >90%, overall survival rates are equivalent to enucleation, and ocular...

Fall 2012
A radiation detector geared towards megavoltage external beam radiotherapy has been developed using a liquid scintillator and a charge coupled device (CCD). The liquid scintillator used is BetaMax ES (MP Biomedicals, Santa Ana, CA) and the CCD comes from an SPC880NC webcam (Royal Philips...

With the advent and development of hybrid Linac-MR technology, we will be able to track and treat lesions in real time. This will permit the narrowing of radiotherapy margins and escalation of dose, augmenting the therapeutic outcome of radiotherapy. The addition of a magnetic field to the...

Dosimetry and Biological Studies for Microbeam Radiation Therapy at the Canadian Light Source
DownloadFall 2015
Microbeam radiation therapy (MRT) is a pre-clinical type of radiation therapy that uses an array of high-dose microbeams to treat solid tumours. An intense, quasi-parallel synchrotron beam is collimated to create microbeams several 10s of μm wide, and separated by 100s of μm. Animal studies...

The dissertation explores some of the limitations and assumptions in the current approach to permanent prostate brachytherapy (PPB) dosimetry. Where possible, novel insights and practical improvements are proposed, which aim to enhance the accuracy of radiation dose delivery during treatment. The...
