Application of 3D printing model of linear accelerator machine to enhance the learning and apprentice performance for the radiological technology student

Abstract

The teaching of instrumentation has consistently been a fundamental component of undergraduate programs in radiological technology (RT). However, opportunities for students to engage in direct, hands-on operation of linear accelerator (LINAC) machines during their education and training are often constrained by financial limitations and time restrictions. Therefore, this study aims to integrate a 3D-printed model into LINAC machine topic and evaluate its effectiveness in teaching RT undergraduate students. To achieve this, a physical LINAC model was developed using fused deposition modeling 3D printing technology, with access facilitated through open-source software. To enhance comprehension, color coding was incorporated along with explanatory color cards. A total of 114 participants were randomly assigned to either a control group or a 3D model group. Comparative analysis of theoretical assessment scores revealed that the 3D model group performed significantly better than the control group, with a p-value of < 0.05. Furthermore, the increased opportunity for hands-on training prior to apprenticeships resulted in reduced anxiety and improved clinical performance among participants in the 3D model group. To assess student perceptions regarding the integration of this novel 3D technology into LINAC teaching, participant feedback was collected. Results indicated that over 94% of students recognized the alternative teaching method as essential for enhancing both their theoretical understanding and practical skills. In conclusion, the incorporation of modern 3D-printed models into RT education demonstrates considerable potential for enriching teaching and training activities, ultimately contributing to improved educational outcomes in radiological technology programs.
