Abstract

Medical Physics is a branch of physics application that is developing very rapidly. Therefore, the contextualization of Medical Physics is crucial for future physics teachers. This research aims to implement Student-Teacher-Scientist Partnerships (STSP) in Medical Physics and explore students' perceptions of the learning experience through this program. STSP in this research involved prospective physics teachers as students, lecturers in medical physics courses as teachers, and medical physicists as scientists. The benefits of this research are to provide a learning experience of medical physics directly from experts (medical physicists) as a provision for prospective physics teachers to strengthen their knowledge of medical physics content and how to teach it, and to be a recommendation for learning strategies that support contextual physics learning. Implementing STSP in medical physics courses includes planning, implementation, and evaluation activities for one semester of lectures; lectures by the foremost scientists were held in 7 meetings (1 meeting = 2 x 60 minutes). The planning stage includes activities to equalize perceptions between scientists and related lecturers. The course was primarily student-centred, with case study discussions conducted online via Zoom meetings. The scientists were located in East Java Province, Indonesia, while the teachers and students were in East Kalimantan Province, Indonesia. The evaluation stage was carried out by exploring students' perceptions of the program implementation, the results of which can later be used as a reference for the continuation of the program implementation. Results indicated that STSP activities facilitated easier comprehension of medical physics, increased interest in further study, and highlighted connections between course topics and secondary school curriculum.

Abstract

Background: The Multi-Leaf Collimator (MLC) application is utilized in the Linear Accelerator (LINAC) with Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) methods, both of which include advanced methods of administering radiotherapy, which aim to improve dose distribution and increase local tumour control by adjusting the external beam into a shape-specific tumour. Dosimetry audit is a crucial quality assurance procedure in radiotherapy facilities, ensuring patient dosing quality. This study aimed to simulate the dosimetry audit method of IMRT techniques and VMAT with point dose and dose delivery distribution evaluation. Method: The phantom utilized in this study was constructed from acrylic material and featured a C-shaped insert. It comprised a main body and an insert, with the body measuring 15 × 15 × 15 cm and the insert measuring 6 × 6 × 6 cm. The main body was fabricated from polymethyl methacrylate (PMMA) with a density of 1.17 g/cm³, serving as a surrogate for human tissue. The insert, composed of a resin and carbon powder mixture with a density of 1.19 g/cm³, was designed to represent both the organ at risk (OAR) and the planning target volume (PTV) in the study. Phantom images were taken with the center of the CT simulator, then radiation planning was performed with a PTV dose of 4 Gy/2 fractions (D95% 95%, D2% 107%, and Dmax 110%) and a maximum OAR dose of 2.8 Gy. This study was conducted at four radiotherapy centres in East Java province by conducting dosimetry audits on point doses using TLD and dose distribution by evaluating gamma index analysis using EBT3 Film.Results: The results of point dose readings using TLD at all centres and radiation techniques were still within the tolerance limit, namely ± 5%. Apart from that, to evaluate the gamma index using film, at three centres with the 3%/3mm criteria, the gamma passing rate was 90%. Conclusion: This method can be used as a reference in conducting dosimetry audits in radiotherapy using TLD and film
