为了更好地研究M RI成像技术和图像重建算法，采用M atlab图形用户界面创建了M RI仿真平台。该平台模拟了线性、螺旋及并行扫描3种成像方式，可以导入不同模型图像，设计K空间扫描轨迹，模拟K空间数据采集过程，显示采集信号的波形。对这3种成像方式的图像重建加以实现，并对重建误差进行了分析。该平台为其它各种M RI数据采集和图像重建新算法的研究提供了一种有效工具。%In order to study the MRI techniques and image reconstruction algorithm better ,the Graphical User Interface of Matlab software is adopted to build a MRI simulation platform .The platform simulates linear ,spiral and parallel imaging scanning in three ways ,which can import images of different models ,design the trajectory of K-space ,simulate the process of K-space data acquisition ,and display signal waveform .This platform also realizes the reconstruction of three image methods and analyses the reconstruction error .It provides a available tool for the later study of new algorithm of data acquisition and image reconstruction .
