Machine Learning

Machine learning for intelligent treatment planning

Cancer treatment represents one of the most exciting applications of data analytics and machine learning technologies. Machine learning already supports the identification of diseases and diagnosis, through to treatment planning and aftercare. By analyzing thousands of different data points, advanced algorithms in RayStation* can help clinics save time and increase consistency by automating plan generation and organ segmentation.

*Subject to regulatory clearance in some markets.

Key Features

  • Generate personalized treatment plans in minutes
  • Create organ contours in less than 1 minute with deep neural network models
  • Benefit from validated models based on data from leading cancer clinics
  • Spend less time on repetitive tasks
  • Get more time for patient consultations and complex cases
 

Deep learning capabilities in RayStation help make organ segmentation quicker and more consistent. A high-speed GPU-powered algorithm is capable of producing consistent segmentation results using segmentation models that have been trained and evaluated on clinical data for different body sites. A deep learning model can segment multiple structures in less than one minute.

The world’s first machine learning treatment plan generation module

RaySearch partnered with Princess Margaret Cancer Center in Canada to develop the world’s first machine learning treatment plan generation module. In May 2019, patients with localized prostate cancer were treated using machine learning treatment plans generated in RayStation as part of a compensative evaluation study. See the study here

RaySearch received 510(k) clearance from the U.S. Food and Drug Administration for RayStation 8B , which was the first machine learning applications in a treatment planning system on the radiation oncology market today.

Clinics can get personalized treatment plans in RayStation to benefit from the experience of one of the world’s leading cancer centers, generated in minutes by selecting a pre-trained machine learning model. One or multiple deliverable treatment plans can be automatically generated with varying target/OAR tradeoffs.

RaySearch licenses UHN automation technologies

University Health Network (UHN) in Canada exclusively licensed its advanced technology to RaySearch for incorporation into RayStation. The technology was developed by the Techna Institute, which is a collaboration between UHN and the University of Toronto. Watch this video to get insights into licensed techniques that have led to machine learning algorithms from Princess Margaret Cancer Center being integrated into RayStation.

Automation and machine learning in RayStation

We will cover the wide variety of tools and modules available which are clinically in use today, offering efficiency, quality and consistency to cancer centers around the world.

 

INTERVIEW WITH FREDRIK LÖFMAN

Physics World met up with Fredrik Löfman, Head of Machine Learning at RaySearch, at 2019 ASTRO Annual Meeting in Chicago to discuss how machine learning capabilities in RayStation can help revolutionize treatment planning.

 

“Machine learning is a natural fit for automating the complex treatment planning process. We expect it will enable us to generate highly personalized radiation treatment plans more efficiently, thereby allowing clinical resources or specialist technical staff to dedicate more time to patient care. Deemed clinically acceptable by experts around the world, RayStation algorithms generate high-quality treatment plans that are preferred or deemed equivalent to clinical plans.”
