“…The scatter radiation dose levels with and without the lead shielding at various distances were compared using Eq. 2, considering the percentage dose difference [22]. Moreover, all results at different chest X-ray positions, distances, and directions were analyzed using the independent Student's paired t test.…”

The COVID-19 pandemic has resulted in a large increase in the number of patients admitted to hospitals. Radiological technologists (RTs) are often required to perform portable chest X-ray radiography on these patients. Normally, when performing a portable X-ray, radiation protection equipment is critical as it reduces the scatter radiation dose to hospital workers. However, during the pandemic, the use of a lead shield caused a heavy weight burden on workers who were responsible for a large number of patients. This study aimed to investigate scatter radiation doses received at various distances, directions, and positions. Radiation measurements were performed using the PBU-60 whole body phantom to determine scatter radiation doses at 100-200 cm and eight different angles around the phantom. The tests were conducted with and without lead shielding. Additionally, the doses were compared using the paired t test (p < 0.005) to determine suitable positions for workers who did not wear lead protection that adhered to radiation safety requirements. Scatter radiation doses of all 40 tests showed a highest and lowest value of 1285.5 nGy at 100 cm in the anteroposterior (AP) semi upright position and 134.7 nGy at 200 cm in the prone position, respectively. Correlation analysis between the dosimeter measurement and calculated inverse square law showed good correlation, with an R 2 value of 0.99. Without lead shielding, RTs must stay at a distance greater than 200 cm from patients for both vertical and horizontal beams to minimize scatter exposure. This would allow for an alternative way of performing portable chest radiography for COVID-19 patients without requiring lead shielding.

The teaching of instrumentation has consistently been the subject of undergraduate program in radiological technology (RT). However, opportunities for students to engage in face-to-face operation of linear accelerator machine (LINAC) during their education and training processes have been limited by financial and timeframe considerations. So, the aim of this study is to integrate a 3D-printed model and assess its effectiveness in teaching LINAC to RT undergraduate students. For this purpose, a LINAC physical model was developed using a fused deposition modeling 3D printer, with access through free online software. Color coding was implemented alongside with explanatory color cards to enhance understanding. A total of 114 participants were randomly divided into two groups: a control group and a 3D model group. Compare the theoretical scores of the 3D model group were found to be significantly higher than those of the control group, with p-value < 0.05. Moreover, the increase in student opportunity for hand-on training prior to their apprenticeships allowed participants in the 3D model group to reduced anxiety and better performance in clinical situation. To summarize participant feedback regarding the integration of this novel 3D technology in the context of LINAC learning and training. Results indicated that over 94% of students perceived the alternative teaching method as essential for enhancing both of their understanding and practical performance. In conclusion, the use of modern 3D-printed models technology, presents a potential tool for stimulating teaching and training activities, thereby improving overall educational outcomes in RT programs.
