RaySearch completes major expansion of RayStation platform at Princess Margaret Cancer Centre

University Health Network’s Princess Margaret Cancer Centre (PMH) in Toronto, Canada has increased the number of RayStation licenses as part of a phased approach to full implementation of the RaySearch Treatment Planning System. The purchase also includes RayStation’s Plan Explorer functionality, which makes it possible to automatically generate a large number of plans for defined clinical goals and combinations of treatment techniques and machines.

The purchase covers the core RayStation technologies –3D-CRT, IMRT, VMAT, deformable registration, dose tracking and multi-criteria optimization along with some additional technologies such as radiobiology and virtual simulation. PMH has decided to implement six Plan Explorer licenses to determine how the new technology might further streamline planning, both in terms of automation and exploring possible treatment solutions.

Dr. Fei-Fei Liu, Chief of the Radiation Medicine Program at PMH says: “The team at Princess Margaret Cancer Centre has done a lot of work and retrospective analyses to determine the best technologies and treatment approaches for the future. We are very optimistic about how we can implement adaptive radiation therapy and further automate treatment planning to optimize our treatment approaches and improve care for our patients. We believe these technologies will continue to allow us to create high quality treatment plans, more efficiently than ever before.”

Johan Löf, CEO of RaySearch, says: “We have an excellent and longstanding partnership with PMH and I am delighted to be able to support them in developing tomorrow’s cancer treatment approaches. With this agreement, PMH is on the way to being one of the biggest RayStation installations in the world.”
