RAYSTATION CUSTOMER EXPERIENCE – LEEDS CANCER CENTRE

Located on Level-2 of the Bexley Wing at St James's Hospital, Leeds Cancer Centre’s radiotherapy department is one of the largest singlesite centers of its kind in the UK. The center’s clinicians deliver personalized treatment plans using machine learning functionalities available in treatment planning system RayStation®.

UP-TO-DATE TREATMENT, CARE AND SUPPORT Leeds Cancer Centre opened in 2008 and is part of Leeds Teaching Hospitals NHS Trust, which has more than 18,000 employees. More than 7,500 new patients are treated annually from a catchment population of around 2.8 million people. Specialists at Leeds Cancer Centre diagnose and treat cancer for the people of the city and the nearby Yorkshire region, providing some of the most up-to-date treatment, care and support for cancer patients.

Radiation therapy treatments available include external beam radiotherapy, brachytherapy and gamma knife. A total of ten clinical linear accelerators (linacs) are installed at the center, along with two dedicated research-funded linacs with advanced image-guided radiation therapy capabilities.

DEEP LEARNING SEGMENTATION Pertinent functionalities include deep learning segmentation for lung contouring during breast radiation therapy. The latest innovation in this area is the RaySearch thorax deep-learning auto-contouring (DL-AC) solution, which outperforms AutoBreast.

ACCURATE CONTOURING During breast radiation therapy planning, accurate lung contouring is crucial for estimating the organs at risk dose. Previously, automatic lung contours produced by the AutoBreast method in RayStation typically required manual editing to improve accuracy. Clinicians at Leeds Cancer Centre found that RaySearch thorax DL-AC model provides fast and excellent performance for ipsilateral lung contouring in the hypofractionated breast radiation therapy scenario. Given the positive results from RaySearch thorax DL-AC model, radiation oncologists in Leeds are now working closely with RaySearch to develop other machine learning models for the safe and effective clinical implementation at other treatment sites.

The standard functionality available in RayStation is impressive, and is sure to enhance our treatment planning processes. We’re confident that the improved functionality and efficiency savings will bring major benefits to the patients that we treat at the Leeds Cancer Centre.

Head of External Beam Radiotherapy Physics, Leeds Cancer Centre, UK

RayStation's machine learning technology has opened up new and exciting possibilities both in the clinic, and for research. We are excited to partner with RaySearch to develop new applications and drive the clinical implementation of AI in Leeds. RaySearch's rapid and responsive customer support has been key to our successful collaboration in this cutting edge work. We were able to implement a traceable and quality managed ML segmentation approach in Leeds which will result in considerable improvements in efficiency and consistency of contouring for our patients.
