Positioning & Immobilisation Focus Group

The Focus Group on Positioning and Immobilisation (P&I) aims to harmonise radiotherapy practices with the current state of research to establish best practice guidelines and enhance patient safety. By identifying gaps in scientific knowledge, education, research, and quality of care, the Focus Group addresses challenges in patient setup and stability, including motion management and position verification.

We defined three working groups:

  • Patient setup and stability
  • Motion management
  • Position verification

The purpose of these working groups is to find out the challenges and aims. Patient information/education runs like a common thread through all working groups.

The P&I Focus Group proposes and assists in the development of guidelines, conducts educational events, distributes and analyses surveys, and advises on the scientific content of the annual ESTRO congress.  In addition to the ESTRO Councils and Committees all radiation oncology experts can contact the Positioning & Immobilisation Focus Group with their questions or (innovative) ideas. The P&I Focus Group is looking for stakeholders in the field of radiotherapy who want to join a working group and contribute their knowledge with the P&I Focus Group.

Education: Evidence-based guidelines. Multi-professional educational events. Patient education.

Technology: Motion management, IGRT, SGRT, 3D printing technology, radiation therapist led online adaptive treatment

Research: performing systematic reviews, surveys

SGRT: From Guideline to Clinical Practice

Following the publication of the SGRT guideline in 2022 [DOI: 10.1016/j.radonc.2022.05.026], the concept of organizing a dedicated SGRT workshop was immediately raised. A dedicated subgroup of this team, integrated into the FocusGroup Positioning & Immobilisation, drove the initiative forward.

In a landmark event at the end of October 2025, this idea culminated in an workshop held in the vibrant city of Maastricht, the Netherlands.

In collaboration with Maastro and several SGRT vendors, we brought together radiation therapy professionals from across Europe for the first International Workshop on Surface Guided Radiation Therapy (SGRT). Leading experts unveiled the latest insights into SGRT implementation, clinical application, and new developments. The presence of all vendors on-site fostered a uniquely interactive atmosphere for essential knowledge sharing.

The ESTRO-endorsed workshop offered a powerful combination of expert-led presentations and practical, vendor-supported training, including  hands-on sessions.

A heartfelt thank you to all participants who contributed to making this workshop a true success!

Coming soon:

Survey on setup, positioning and immobilisation  

With this survey we want to collect information about existing guideline and work instructions for setup and positioning & immobilisation. Also we want to get knowledge if there are gaps that we need to fill.

By participating in this survey, you will provide information that reflects the needs of ESTRO members. Your contributions will help us understand how. With this we aim to improve the care for our patients and improve their radiation treatment.

RTT-driven online ART: webinar and framework manuscript

The FG P&I wants to share this knowledge amongst the ESTRO community throughout Europe.
