Position Summary:
The Radiation Medicine Program (RMP) at the Princess Margaret Cancer Centre is dedicated to providing exceptional patient care and advancing innovative research in radiation oncology. As a comprehensive program, RMP is focused on improving patient outcomes through state-of-the-art technology, clinical trials, and interdisciplinary collaboration. The team works closely with clinical, research, and educational partners to improve radiation therapies and contribute to cutting-edge advancements in cancer treatment.

Magnetic Resonance Linear Accelerator (MR Linac, MRL) technology enables daily adaptation of radiation treatment plans based on real-time MR imaging of patient anatomy. This adaptive approach reduces uncertainties related to inter- and intra-fraction motion and patient setup.

Despite these advances, planning organ-at-risk margins (PRVs) remain largely derived from conventional radiotherapy approaches and may lead to compromised target coverage—particularly in abdominal malignancies such as pancreatic cancer, where tumors are adjacent to highly radiosensitive luminal structures. At our institution, a 5 mm PRV margin is currently used for luminal organs. This project will evaluate the effectiveness of this margin in pancreatic cancer cases, with a focus on treatments involving dual dose levels where target under-coverage is frequently observed due to PRV constraints.

The summer student will support a research project focused on optimizing planning organ-at-risk margins (PRVs) for pancreatic cancer treatments on the MR-guided radiotherapy (MR Linac) platform at Princess Margaret Cancer Centre. Working with a multidisciplinary team of physicists and clinicians, the student will collect and curate dosimetric data, export and manage treatment plans across planning systems, and assist with deformable image registration and dose accumulation using established in-house pipelines. These efforts will contribute to evaluating whether current PRV margins can be safely reduced without compromising target coverage.

In addition, the student will perform data analysis using existing scripts and standard analytical tools to assess treatment plan quality and margin effectiveness. They will document methodologies, track progress, and present findings at regular team meetings. Through this work, the student will gain hands-on experience with MR-guided adaptive radiotherapy workflows and contribute to research that supports future advancements, including real-time motion management and margin reduction strategies.

Duties:

• Acquire the dosimetric data needed for analysis using EVOQ.
• Export treatment plans from Monaco treatment planning system to RayStation treatment planning system for dose accumulation.
• Perform deformable image registration under supervision.
• Perform dose accumulation using the in-house developed pipeline in RayStation.
• Perform data analysis using the in-house developed scripts as well as data analysis tools.
• Maintain documentation of methodology, progress, and results.
• Attend weekly progress report meetings.

Qualifications

• Must be 16 years of age or older, per UHN policy
• Your appointment runs between May 2026 - August 31, 2026
• Currently enrolled in a relevant Undergraduate program (e.g., Radiation Sciences, Biomedical Sciences, Health Sciences, etc.).
• Experience with data and statistical analysis
• Excellent organizational and communication skills, both written and verbal.
• Ability to work independently and in a team-oriented environment.
• Proficiency in Microsoft Office (Excel, Word, PowerPoint).
• Previous research experience is an asset but not required.
