【摘要】：近年来，伴随着磁共振成像（Magnetic Resonance Imaging, MRI）在医疗方面的迅猛发展，MRI影像技师的队伍也在逐年的扩大。但MRI设备昂贵，体积庞大，安装过程繁琐，极不方便移动，这些给MRI操作技师最初的学习带来很大的麻烦。日常教学过程中，技师学员在课堂上极少有机会能够接触到实际的MRI设备，欠缺实际操作经验。并且，近年来，患者在就诊过程中自我保护的意识正在逐渐增强，而实践技师的人数却在逐年增多，传统的直接以病人为实践对象的教学模式，已经不能给MRI操作技师的初学者提供足够的实际操作机会，鉴于此，本文结合MRI临床检查的具体操作情况，研究并设计开发了具有实时反馈和人机交互控制的MRI技师培训系统。首先基于虚拟现实建模技术，研究了MRI实时交互虚拟培训系统的建模的方法和流程，构建了虚拟诊室的场景和MRI仪器各部件的虚拟模型。然后，，借助EON软件开发工具，利用虚拟现实中的视点跟踪，碰撞检测，物体拾取，数据实时反馈和网络发布等关键技术，完成了MRI虚拟诊室漫游，MRI虚拟设备的拆卸与安装和MRI临床检查扫描过程的仿真交互练习等人机实时交互控制功能的开发。最后，采用VC++6.0为开发工具，运用与SQL数据库无缝连接的方法，建立了病人信息记录表，并对人机交互式图像分割算法等方面进行了研究，完成了对MRI软件培训系统中MRI扫描控制，影像中病灶标记及测量，图像排版及打印和病人信息归档及查询这四个主要的功能模块的开发，实现了从硬件方面到软件方面对MRI影像技师的初学者全方位的虚拟培训。经验证，本文研究并开发的MRI实时交互虚拟培训系统可以为MRI影像技师的初学者提供MRI操作全过程的虚拟培训，并可以进一步的规范MRI临床检查的操作过程，能够起到考核和辅助教学的作用，并且系统操作简单易用，运行稳定良好，有较高的实用价值。
[Abstract]:In recent years, with the rapid development of magnetic resonance imaging (MRI) in medical field, the number of MRI imaging technicians is expanding year by year. However, MRI equipment is expensive, bulky, the installation process is cumbersome, extremely inconvenient to move, which brings great trouble to the initial learning of MRI operator. In the course of daily teaching, technicians rarely have access to actual MRI equipment in class, and lack practical experience. Moreover, in recent years, patients' awareness of self-protection in the process of attending medical treatment is gradually increasing, while the number of practical technicians is increasing year by year. It has not been possible for the beginners of MRI operation technician to have enough practical operation opportunity. In view of this, this article combined with the specific operation of MRI clinical examination, An MRI technician training system with real-time feedback and interactive control is studied and developed. Firstly, based on the virtual reality modeling technology, the modeling method and process of MRI real-time interactive virtual training system are studied, and the scene of virtual diagnosis room and the virtual model of each part of MRI instrument are constructed. Then, with the help of EON software development tools, the key technologies of virtual reality, such as view tracking, collision detection, object pickup, real-time data feedback and network release, are used. The disassembly and installation of MRI virtual equipment in MRI virtual diagnosis room and the simulation interactive exercise in the course of MRI clinical examination and scanning were completed. The function of man-machine real-time interactive control was developed. Finally, using VC 6.0 as the development tool and using the method of seamless connection with SQL database, the patient information record table is established, and the human-computer interactive image segmentation algorithm is studied. The four main function modules of MRI scanning control, image marking and measurement, image typesetting and printing, patient information archiving and querying in MRI software training system have been developed. From the hardware aspect to the software aspect to the MRI image technician beginner's omnidirectional virtual training. It is proved that the real time interactive virtual training system of MRI developed in this paper can provide virtual training for the beginners of MRI imaging technician in the whole process of MRI operation, and can further standardize the operation process of MRI clinical examination. It has the function of examination and assistant teaching, and the system is simple and easy to use, running stably and well, and has higher practical value.
