specific course is provided, so RTTs using different vendors can attend and employ the obtained skills in their own department. The competencies of the course are based on Dublin descriptors. The course consists of a 10 day education and can be divided in 3 parts: 1) Pre-treatment MRI and MR physics, 2) Image registration and MR only workflows and 3) online adaptive MRgRT. The first and second part the students focus on preparation and processing assignments and the third part they focus on a practice oriented research project in collaboration with their own department. The end assessment is a written report portfolio containing all assignments and research project. Furthermore two site visits are organized to see workflows of both MR-Linac systems. A document of study load and learning objectives was compiled. The study load is 60 hours compulsory attendance at the Fontys University and 261 hours of self-study. The course was evaluated with a written survey using a 5 point Likert scale at 2 time-points during the course and by oral evaluation. Results The average outcomes of the survey are presented in figure 1. Overall the course is evaluated with a score of 4.4 out of 5. The teachers were evaluated with a score of 4.9 out of 5. Not all students had good access to an MRI or MR-Linac in their department, for them it was more difficult to apply the obtained knowledge in daily practice. Moreover the starting knowledge of every student is different whereby for some participants the lessons of MR physics were scored as very difficult. The site visits were evaluated with a high score.

Conclusion This course provides a perfect fit to new MRgRT developments in daily clinical practice for RTTs. An informative vendor neutral course was designed, which can be a part of the Master program of Medical Imaging and Radiation Oncology. The course was evaluated with good scores. A next step will be assessing if there is an international need for such an education program.

Purpose or Objective Introduction

Incidental irradiation of the heart can have long-term consequences. Deep Inspiration Breath Hold (DIBH) is used for patients receiving radiotherapy for breast cancer to reduce heart doses. Using DIBH, mean heart dose can be reduced by up to 67% compared with free breathing. DIBH is an accepted technique for breast cancer radiotherapy. However, a survey of a breast radiotherapy interest group (BRIG) identified patient compliance, ability to hold their breath for the required time, and reproducibility of breath hold as major challenges to implementing DIBH. Between 12-21% of patients are reported to find the technique challenging; resulting in a proportion of patients missing out on the benefits of DIBH. While coaching can reduce maximum heart dose compared with non-coached patients, formal coaching is unavailable in some centres and no standard patient resource was available to inform patient preparation prior to radiotherapy planning. Purpose To develop a series of instructional videos to enhance the number of patients that can achieve breath hold, improve patient self-efficacy and increase patient satisfaction with care.
