Christopher Roy, Maître assistant (SNSF Ambizione), Department of Radiology – Lausanne University Hospital (CHUV), University of Lausanne (UNIL).
Christopher Roy graduated with an honors in physics BSc degree from Mount Allison University, in Canada, in 2010. He completed his MSc in 2012 and PhD in 2017, both in Medical Biophysics at the University of Toronto. Working with Drs. Christopher Macgowan and Mike Seed at the Hospital for Sick Children in Toronto, Chris’ graduate research focused on accelerated imaging and motion correction strategies for MRI of the fetal heart. This work led to the first retrospectively gated fetal CINE bSSFP images and first application of compressed sensing to dynamic fetal imaging. Chris has a strong interest in using post-processing methods to address practical challenges in clinical applications. Chris is currently a lecturer (maître-assistant) at the Department of Radiology, Lausanne University Hospital (CHUV) and University of Lausanne (UNIL) and is leading a Swiss National Science Foundation Ambizione funded project developing multi-dimensional imaging techniques targeting the fetal and pediatric heart, hosted in CIBM MRI CHUV -UNIL Translational MR Imaging Section.
In recent years, Cardiovascular Magnetic Resonance Imaging has played an increasingly important role in assessing the heart in fetal and pediatric patients, providing a comprehensive 3D assessment of anatomy, function, and blood flow. In general, MRI requires careful compensation of both cardiac and respiratory motion in order to ensure high quality images that are not degraded by artifact. However, in fetal and pediatric imaging the likelihood of bulk patient movement provides an additional confounding factor that may either preclude scanning altogether or require sedation. In this talk, Chris Roy will provide an overview of techniques developed for high resolution dynamic cardiac imaging in the presence of patient movement. With these methods his team aim to improve the ease-of-use of Cardiovascular MRI and work towards decreasing the need for sedation in pediatric patients while also exploring new avenues for imaging the fetus.
The CIBM Breakfast and Science Seminars aim to unite the scientific community on a regular basis (every last Tuesday of the month) so as to exchange knowledge, to foster research collaborations and to create a vibrant research center of excellence in biomedical imaging.
In general a seminar may be composed of one 40 minute or two 20 minute presentation on a specific research area in biomedical imaging followed by a 5-10-minute Q&A discussion.
The event is concluded with a interactive sharing session where audience members have an opportunity to share with each other their news, updates or simply network with members of the CIBM community.
