Symposia Day (DPMB) - Advances in Biological and Medical Physics Symposium

Invited Speaker / Conférencier(ère) invité(e)

Approximately half of all cancer patients require radiation therapy at some point during the management of their disease. Radiation detectors are tools for the quantitative characterization of fields of ionizing radiation used for radiation therapy and are essential for their safe and effective use. The goal of dosimetry measurements is to quantify the amount of energy deposited in the body...

3311. (U*) Retinal Image quality decreases in those with diabetes with increasing duration of disease and inversely with the level of disease control

Oral Competition (Undergraduate Student) / Compétition orale (Étudiant(e) du 1er cycle)

Introduction: The eye’s optics change in those with type 1 diabetes mellitus. Known optical changes could impact both vision and imaging of diabetes-related changes to blood vessels, which are sight threatening. Here we investigate retinal image quality in those with diabetes and healthy controls.
Methods: Using novel methods, retinal image quality was derived for 1200 healthy eyes and 46...

3105. (G*) Dosimetric characterization of modified radiochromic materials: Comparison of photon to proton beam irradiation

Symposia Day (DPMB) - Advances in Biological and Medical Physics Symposium

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

A quantitative real-time in vivo evaluation of ionizing radiation delivered to patients during a radiotherapy procedure is critical to assure patients receive treatments with rigorous quality control. Current dosimeters are not well suited for simple and direct measurements due to atomic composition, requiring correction to dose distribution, and probe size limitations. We are developing a...

3115. Optical Coherence Tomography as a Screening Tool for Oral Cancers

Dr Christopher Schruder (York University, Department of Physics and Astronomy)

07/06/2022, 16:15

Symposia Day (DPMB) - Advances in Biological and Medical Physics Symposium

Oral (Non-Student) / Orale (non-étudiant(e))

Structural optical imaging within tissues is potentially useful for medical screening of various diseases, and particularly suitable for superficial and easily accessible oral cancers. Optical coherence tomography (OCT) is a non-invasive, low coherence imaging technique that allows micron-scale resolution for structural determinations within tissues. Intensity data from OCT images can be used...

3280. Iron Microparticle Cluster Quantification In Vitro Using Pure Phase Encoding Magnetic Resonance Imaging

Layale Bazzi (University of Windsor)

07/06/2022, 16:30

Symposia Day (DPMB) - Advances in Biological and Medical Physics Symposium

Oral (Non-Student) / Orale (non-étudiant(e))

Magnetic Resonance Imaging (MRI) is a non-invasive medical imaging modality that
provides excellent soft tissue contrast and resolution. MRI cell tracking effectively monitors cell migration in various immunotherapies where cells are labelled with high susceptibility iron oxide particles to create a negative contrast in the image. However, it is not possible to quantify the number of cells as...
