Adaptive Approaches and Online Monitoring of Radiotherapy Treatment

25 April 2018


Organised by IPEM's Radiotherapy Special Interest Group

Following our recent call for papers for the Online Monitoring of Radiotherapy Treatment meeting we have received a number of high quality submissions, but have identified a gap in proffered topics, relating to adaptive approaches.  We have re-opened submissions and encourage authors to submit their “Adaptive approaches to Radiotherapy Treatment”.  Case reviews, clinically implemented adaptive approach paradigms and emerging/proof of concept submissions are encouraged. Submission deadline 1st March. 

The emerging MR-Linac platform may provide the ultimate panacea, though still to be clinically implemented in the UK, Dr. Michael Roach, will give a keynote address highlighting the practical implementation and patient benefits that can be realised.


Only a mere 20 years ago, you could be forgiven for thinking radiotherapy patients did not move and their tumours did not change during treatment! We know this because radiotherapy treatments were set up to external fiducial markers and treatment delivered with no, or little, image verification. Treatment borders were large and required no further validation. However whilst treatments were effective, side effects were prevalent.

Wind the clock forward to 2018. The demands on the radiotherapy delivery system have increased significantly with the introduction of new techniques and technologies. Tumours are no longer considered square and static, margins are tighter and there is a real need for validation and verification of treatment in real time, on an individual patient basis.  Online monitoring is therefore becoming a desirable feature to be fully incorporated in modern radiotherapy, as a means to avoid errors, verify treatment delivery and highlight changes in machine performance. It also plays a major role in adaptive treatment where imaging can inform not only positioning but also the need for re-planning.

Many contemporary technologies may be employed to monitor radiotherapy treatment in real, or near-real time to provide assurance. These include systems such as:

  • In-vivo diodes,
  • EPID (Electronic Portal Imaging Device) imaging and dosimetry,
  • glass beads thermo-luminescent dosimeters,
  • non-orthogonal Image based monitoring,
  • ultrasound imaging, optical surface tracking,
  • MRI (Magnetic Resonance Imaging) on the Linac,
  • Electromagnetic transponders,
  • treatment machine log file analysis and reconstruction, and
  • optical and physical delivery gating systems.

Despite recommendations made in 2010 (Towards Safer Radiotherapy) and 2012 (NRIG IGRT Guidance for Implementation and Use),  to use real time monitoring systems to reduce and correct uncertainty resulting from patient physiological movements, online monitoring technology for Radiotherapy Treatment is yet to mature and be fully integrated in clinical pathways in radiotherapy departments.

Target audience
Radiotherapy Professionals (Scientific/Technical, Radiography, Oncologists)

Educational Aims
1. To provide a stimulating forum for the exchange of ideas regarding online monitoring and how it is developing, as well as how it fits in within the wider spectrum of QA methods.
2. To provide an opportunity for users to learn how to overcome any issues they are encountering so they can fast track implementation. 
3. Provide information to delegates about the different commercial and in-house systems that have been developed to support online radiotherapy treatment monitoring and to expand ideas on the intended use of commercial monitoring systems to new novel applications within radiotherapy

Anticipated Learning Outcomes
1. Learning outcomes will include an understanding of the status of online monitoring systems currently available, together with those under development.

2. Delegates are expected to be able to describe different equipment and modes of use for various commercial and in-house online monitoring systems and be able to identify the benefit that these systems bring to patient treatment.

3. Delegates will be able to identify gaps in their own local radiotherapy services and utilise information provided during the meeting to plan future developments and implementations to support improved patient treatment.  Attendees will also learn about implementation issues for commercially available systems within the UK and learn who are the key players in this field, for networking opportunities.
Abstract submission
Abstract submissions are invited from interested professionals in healthcare, industry and academia. Presentations in all relevant areas and disciplines are welcome.

We are inviting submissions for this meeting which will explore the current and future patient benefits of implementing all types of online monitoring techniques and technologies for Radiotherapy Treatment.   The meeting will provide an opportunity for those working with relatively new systems to share details as well as manufacturers talking about their systems.  Presentations from researchers working with experimental systems are encouraged.
