摘要 针对医学生在进行侧脑室额角穿刺模拟手术时缺乏图像引导、易遗忘、训练效果差等问题,本研究提出了一套基于增强现实眼镜技术的侧脑室额角穿刺辅助系统。基于一例侧脑室轻度扩大患者的头部CT及MRI数据,采用医学建模软件Minics对颅脑各部分组织结构的灰度特点进行阈值分割,构建三维虚拟模型;其次,使用Vuforia SDK及Unity 3D进行增强现实构建,提出了一种主识别图搭配开启图的定位方法,系统平均配准误差为1.333 mm;最终将系统导入增强现实眼镜完成调试。邀请20名医学院临床专业的在读学生并分为佩戴增强现实眼镜与未佩戴增强现实眼镜的两个组,进行侧脑室额角穿刺模拟手术操作并对模拟手术进行问卷评分。结果表明,与未佩戴增强现实眼镜的组相比,佩戴增强现实眼镜的组在手术操作中所用的平均时间缩短了4.71 min,穿刺成功率提高了30%,且佩戴增强现实眼镜的组别所反馈问卷评分结果明显优于对照组。所搭建的基于增强现实眼镜技术的侧脑室额角穿刺辅助系统能够显著提高手术训练效果,可为提升侧脑室额角穿刺的手术训练质量提供一种新思路。

Abstract:To address the problems of lacking image guidance, prone to forgetting, and poor training results during simulated lateral ventricle puncture experienced by medical students, this study proposed an augmented reality (AR) glasses-based lateral ventricle puncture assistance system. Based on the CT and MRI data of a patient with mild lateral ventricle enlargement, the medical modeling software Mimics was used to threshold segment the gray characteristics of various tissue structures in the skull and brain, and a 3D virtual model was constructed. Next, AR construction was performed using Vuforia SDK and Unity 3D, and a method of combining the main recognition image with the opening image was proposed to obtain an average registration error of the system of 1.333 mm. At last, the system was imported into AR glasses and debugged. Twenty clinical medical students were invited to participate and were divided into two groups: one wearing AR glasses and the other not. They performed simulated lateral ventricle frontal horn puncture operations and scored the simulated surgery using a questionnaire. The test results showed that compared with the group not wearing AR glasses, the group wearing them used an average of 4.71 minutes less time during the operation, and the success rate of puncture increased by 30%. Furthermore, the group wearing AR glasses gave significantly better feedback on the questionnaire evaluation than the control group. In conclusion, the AR glasses-based lateral ventricle puncture assistance system built in this study can significantly improve the training effect of the surgery and provide a new idea for improving the quality of lateral ventricle puncture surgery training.
