Title: CycleGAN and Medical Imaging: Enhancing Onboard CBCT Scanners for
Rapid Palliative Care Workflow in Spine Metastases
By Mehan Haidari, Carleton University
Supervisor: Dr. Elsayed Ali, The Ottawa Hospital Cancer Centre
In this presentation, we will investigate the potential of the CycleGAN, a
type of generative adversarial network capable of unsupervised and
unpaired image-to-image translation tasks, to streamline rapid palliative
workflows for spine metastases. We will examine the use of CycleGAN in
transforming onboard CBCT images, traditionally employed for positioning
accuracy in image-guided therapy, into high-quality synthetic CT images
suitable for precise targeting and treatment planning. The discussion will
provide an overview of the CycleGAN architecture and training process, as
well as strategies for improving model performance.

Title: Blurring the lines between diagnostic imaging and radiation
therapy: how imaging quality improvement tools can be applied in RT
By Dr. Lesley Buckley, The Ottawa Hospital Cancer Centre
Imaging plays an integral role in radiation therapy and many treatment
techniques rely heavily on the information provided by improved imaging
both at the time of simulation and treatment. Although radiation therapy
programs have comprehensive quality assurance programs, there are few
examples of using the approaches common to diagnostic imaging to assess
the imaging aspects of the program. Within diagnostic imaging, there are
well established quality improvement tools to assess the performance of
the imaging program and to identify potential areas for improvement, many
of which are mandated by governing bodies. This talk will discuss a
variety of quality improvement tools routinely used in diagnostic imaging
and how they can be applied in the radiation therapy context, with
specific focus on a study of repeat rates in radiation therapy imaging. A
brief discussion of how radiation therapy quality assurance approaches can
inform practice in diagnostic imaging will also be included.
