Detector Development


Youstina Daoud obtained her Baccalaureate in Biomedical Engineering from Saint-Joseph University, Lebanon in 2017. In 2018, she began a professional M.Sc. degree in Biomedical Engineering at Polytechnique Montreal, then in 2019 she moved towards a thesis-based M.S. degree under the supervision of Professor Farida Cheriet and the co-supervision of Dr Hubert Labelle. Her research focused on evaluating the 3D trunk geometry acquisition systems used in the design of personalized braces for scoliotic patients. She is currently a Research Assistant at the Lady Davis Institute for Medical Research in Montreal and works under the supervision of Dr. Shirin Abbasinejad Enger in the Department of Oncology, Medical Physics Unit at McGill University.

Current Projects

Development of a non-invasive radiation detector to measure the arterial input function for dynamic positron emission tomography 
Youstina is working with Liam Carroll on developing a non-invasive detector to measure the amount of radiation in a patient’s arteries. This information is required during dynamic Positron Emission Tomography (dPET), an imaging modality used for the diagnosis and treatment of diseases such as cancer, cardiac diseases, Alzheimer’s and Parkinson’s disease. The developed detector will allow clinicians to measure the arterial input function without withdrawing blood from patients while performing a dPET. 
Mapping of humans’ wrists using a 3D ultrasound
Development of the non-invasive radiation detector requires knowledge of the distances between arteries, veins, bones and the skin in the humans’ wrists. This information will be therefore obtained by mapping the wrists of a large cohort of individuals using a 3D ultrasound.
