信号重构matlab代码便携式MRI 便携式MRI数据的重建和处理代码 概述 portable-MRI包含MATLAB代码,用于通用重建和处理由便携式MRI扫描仪生成的MRI数据。 便携式MRI扫描仪具有内置(始终打开)的读出梯度。 3D RARE序列与二维编码中的相位编码一起使用。 重建代码的输入数据是一个.mat文件,其中包含原始相位编码的自旋回波火车数据。 影像重建HALBACH_reconstruct_simp.m是用于运行图像重建代码的顶级脚本。 提供了示例性体内数据集(T2加权)(T2_data_example.mat)。 图像处理进一步的图像处理是用intensity_correction.m执行的。 该脚本使用自定义蒙版对每个2D图像进行蒙版,并使用低通滤波后的图像版本对图像强度进行归一化。 提供了重建的图像以供加载到此脚本中(T2_images_example.mat)。 可以使用drawfreehand和createMask内置的MATLAB函数创建自定义蒙版。 系统要求 硬件要求 portable-MRI软件包需要一台具有足够RAM的标准计算机来支持内存中操作。
