摘要
文中首先从核磁共振成像技术原理的角度阐述该虚拟软件开发的总体设计思路和虚拟软件整体功能框架,然后从本征组织模型建立、虚拟数据动态采集、核磁共振图像重建三个方面阐述核磁共振成像技术虚拟数据采集与图像重建方法,从软件界面、数据结构两个方面阐述核磁共振成像技术虚拟软件设计开发,最后从预扫描实验、成像实验等方面阐述核磁共振成像技术虚拟软件功能实验,并重点阐述采样数据、SE序列、IR序列、EPI序列等因素对图像成像特点的影响,为核磁共振成像技术教学提供虚拟软件支撑。
In this paper,the overall design idea and overall functional framework of the virtual software development are described from the perspective of the principle of nuclear magnetic resonance imaging technology,and then the virtual data acquisition and image reconstruction methods of nuclear magnetic resonance imaging technology are described from three aspects of intrinsic tissue model establishment,virtual data dynamic acquisition and nuclear magnetic resonance image reconstruction.The design and development of virtual software of NMRI technology are elaborated from two aspects of data structure.Finally,the functional experiment of virtual software of NMRI technology is elaborated from the aspects of pre scanning experiment and imaging experiment.The influence of sampling data,SE sequence,IR sequence,EPI sequence and other factors on image imaging characteristics is mainly elaborated,which provides virtual software support for MRI technology teaching.
