In radiation therapy, patient setup is important for improving treatment accuracy. The six-axis couch semi-automatically adjusts the patient's position; however, adjusting the patient to twist is difficult. In this study, we developed and evaluated a virtual reality setup training tool for medical students to understand and improve their patient setup skills for radiation therapy. First, we set up a simulated patient in a virtual space to reproduce the radiation treatment room. A gyro sensor was attached to the patient phantom in real space, and the twist of the phantom was linked to the patient in the virtual space. Training was conducted for 24 students, and their operation records were analyzed and evaluated. The training's efficacy was also evaluated through questionnaires provided at the end of the training. The total time required for patient setup tests before and after training decreased significantly from 331.9 s to 146.2 s. As a result of the questionnaire regarding the usability of training to the trainee, most were highly evaluated. We found that training significantly improved students' understanding of the patient setup. With the proposed system, trainees can experience a simulated setup that can aid in deepening their understanding of radiation therapy treatments.
在放射治疗中，患者摆位对于提高治疗精度很重要。六轴治疗床可半自动调整患者位置；然而，调整患者使其扭转却很困难。在本研究中，我们开发并评估了一种虚拟现实摆位训练工具，用于帮助医学生理解并提高其放射治疗的患者摆位技能。首先，我们在虚拟空间中设置了一个模拟患者以重现放射治疗室。在真实空间中，一个陀螺仪传感器被附着在患者体模上，体模的扭转与虚拟空间中的患者相关联。对24名学生进行了训练，并对他们的操作记录进行了分析和评估。训练效果也通过训练结束时提供的问卷进行了评估。训练前后患者摆位测试所需的总时间从331.9秒显著减少到146.2秒。关于训练对学员可用性的问卷结果显示，大多数得到了高度评价。我们发现训练显著提高了学生对患者摆位的理解。通过所提出的系统，学员可以体验模拟摆位，这有助于加深他们对放射治疗的理解。
