摘要
提出了一种虚实结合的新型肺穿刺虚拟训练系统,采用毫米波雷达和数字信号处理技术,通过穿刺路径的可视化,实现医学规范化培训过程中医生做肺穿刺训练时的精确评估,克服使用传统仿真假人模型进行肺穿刺训练时的不可视问题。介绍了该训练系统整体设计,并重点阐述了上位机基于卡尔曼滤波的针尖坐标数据的预处理和穿刺路径偏差计算功能的研制与测试。上位机在Unity3D平台下进行开发和测试,测试结果表明上位机通过预处理将下位机针尖初始坐标数据的误差减小到原来的35.2%,并能显示医生在训练时穿刺的路径与理想穿刺路径的最大、最小和平均偏离度。该系统在医学规范化培训领域属于首创,对处于医学规范化培训阶段的医生是一个精准掌握穿刺技术的有效训练工具。
This paper proposes a new type of lung puncture virtual training system combined with reality.The system uses millimeter wave radar and digital signal processing technology.By visualizing the puncture path,the system achieves accurate assessment when doctors perform lung puncture training during standardized medical training,and overcomes the problem of invisibility when doctors use traditional artificial dummy models for lung puncture training.This paper introduces the overall design of the training system,and focuses on the development and testing of the pre-processing of needle tip coordinate data based on Kalman filtering and the calculation of the puncture path deviation of the host computer.The host computer is developed and tested under the Unity3 D platform.The test results show that the host computer reduces the error of the initial coordinate data of the needle point of the host computer to 35.2%by preprocessing.The test results also show that the host computer can show the maximum,minimum,and average deviations of the path taken by the doctor during the puncture training from the ideal puncture path.This system is the first in the field of standardized medical training.The system is an effective training tool for doctors in the stage of standardized medical training to accurately grasp the puncture technology.
