RTT - Education, training, advanced practice and role developments

ESTRO 2025

• Operating theatre skills: surgical scrubbing, equipment set-up, sterility procedures, patient positioning, transabdominal ultrasound imaging, and safe patient transfers. • Magnetic Resonance Imaging (MRI)-related skills: imaging sequence characteristics, MRI acquisition supervision and MRI safety protocols. • Planning skills: reconstruction of applicators and catheters, anatomy identification, target delineation, plan optimisation and plan evaluation. • Treatment procedure skills: pre-treatment ultrasound verification and safe treatment delivery. • Post-treatment skills: applicator removal and management of emergency situations such as bleeding. • Training of other RTTs, research and quality improvement. GynBT RTTs participated in specific structured training in these identified areas to support an expansion of RTTs responsibilities in GynBT. This process was successfully implemented within the centre leading to improved workflow efficiency, better continuity of patient care, and strengthened collaboration between disciplines. The expanded scope of practice has contributed to increased confidence and job satisfaction. Conclusion: The role expansion of GynBT RTTs has resulted in more streamlined workflows, enhanced patient experience and improved resource utilization. By empowering RTTs with these specialized skill sets, job satisfaction increases and integration within the team is consolidated. For wider implementation, a structured competency assessment framework and guidelines are required. Digital Poster Eye tracking analysis in surface-guided radiation therapy positioning: a comparative study of experienced and novice radiation technologists Hidetoshi Shimizu 1,2 , Tomoki Kitagawa 1 , Koji Sasaki 3 , Takahiro Aoyama 1 , Takeshi Kodaira 1 1 Department of Radiation Oncology, Aichi Cancer Center Hospital, Nagoya, Japan. 2 Division of Medical Physics, School of Medical Sciences, Fujita Health University, Toyoake, Japan. 3 Graduate School of Radiological Technology, Gunma Prefectural College of Health Sciences, Maebashi, Japan Purpose/Objective: The patient setup using the surface-guided radiation therapy (SGRT) system differs from conventional surface marker procedures, and there may be operator variability in where to focus for patient setup due to 3-dimensional much information. This study aims to clarify the differences between expert and novice operators in the SGRT positioning for the head and neck case by tracking their eye movements to offer data to develop efficient patient setup procedures. Material/Methods: Six radiation technologists set up a simulated patient on an SGRT system while recording eye movements on the screen using the QG-PLUS eye-tracking system. The positioning time and the number of gaze fixations on the screen were analyzed, and the relationship between years of experience with SGRT, positioning time, and the number of gaze fixations was evaluated. Results: No significant correlation was found between SGRT experience and positioning time (r = -0.67, p = 0.15). However, more experienced radiation technologists showed fewer gaze fixations per positioning session (r = −0.81, p < 0.05), indicating greater efficiency. Additionally, experienced radiation technologists focused more on a specific screen during the latter half of positioning, suggesting a refined approach in final patient alignment verification.
