Effectiveness of radiation protection educational material during angiography using visualization of scattered radiation by augmented reality technique.

In medical settings, radiation exposure among radiation workers is a significant concern, and understanding radiation protection is crucial. We developed and evaluated radiation protection educational materials using an augmented reality application for visualizing scatter radiation. The evaluation included a true/false quiz, a questionnaire based on the ARCS (Attention, Relevance, Confidence, and Satisfaction) model, and open-ended responses. The correct response rates for the true/false quiz were 65.5% and 72.4% for two questions regarding the effect of C-arm angle changes on scatter radiation distribution. The correct response rate for all other questions was 100%. Understanding how changes in C-arm angles specifically affect angiographic procedures proved more challenging than other topics. The ARCS model evaluation of learning motivation revealed average scores of 4.15 for Attention, 3.91 for Relevance, 3.93 for Confidence, and 4.28 for Satisfaction in the scale 5.00.These results suggest that the developed materials are effective in enhancing motivation. However, open-ended responses identified areas for improvement in the application's usability, particularly regarding ease of operation. While the materials successfully enhance motivation, further refinements are needed to address the variation in correct response rates across different scenarios and the usability challenges of the application.
