Name Position Research
Cheryl Duzenli Adjunct Professor, Medical Physics Research Team
Nancy Ford Associate Member, Medical Physics Research Website
Research Field: X-ray imaging, micro-computed tomography, dental x-ray imaging
Topics Include: Denoising preclinical micro-computed tomography images for improved regional analysis of the lungs and pulmonary vasculature in a mouse model of Chronic Obstructive Pulmonary Disease:
We are training CNNs to remove artifacts and noise from respiratory-gated micro-computed tomography images. By removing structural noise and artifacts, we expect to improve the accuracy of measurements obtained from these images.

In Vivo monitoring of FLASH radiation therapy:
We have completed the first 10 MV photon FLASH radiation therapy treatments in mice at the TRIUMF particle accelerator. We are using micro-CT imaging and image-based analysis to monitor any changes in lung structure and function following FLASH radiation therapy treatments. This proof-of-concept study will determine if FLASH treatments have a reduction in healthy tissue damage.
