实验三：MR图像与K空间数据关系实验（设计型）

一、实验目的及要求：

用MATLAB探究MR图像与K空间数据之间的关系。具体要求如下：

1．由提供的MR图像得到对应的K空间数据并显示K空间数据幅度谱；

2．隔行删除K空间数据并显示其幅度谱，由隔行删除后的K空间数据重建MR图像，观察图像的改变。

3．隔列删除K空间数据并显示其幅度谱，由隔列删除后的K空间数据重建MR图像，观察图像的改变。

4．隔行、隔列删除K空间数据并显示其幅度谱，由隔行、隔列删除后K空间数据重建MR图像，观察图像的改变。

5．通过矩阵操作语句删除K空间高频数据（或设计一个低通滤波器滤除高频数据）并显示其幅度谱，由处理后的K空间数据重建MR图像，观察图像的改变。

6．通过矩阵操作语句删除K空间低频数据（或设计一个高通滤波器滤除低频数据）并显示其幅度谱，由处理后的K空间数据重建MR图像，观察图像的改变。-Experiment 3: MR images and the K space data relationship experiment (design)

A, experiment purpose and requirements:

MATLAB to explore the MR images and the relationship between the K space data. Specific requirements are as follows:

1. By providing the MR images of spatial data and display the corresponding K K space data amplitude spectrum

2. Delete interlaced K space data and displays its amplitude spectrum, after deleting the interlaced K space data reconstruction of MR images, to observe the change of the image.

3. Delete every column K space data and display its amplitude spectrum, by every column K space data reconstruction of MR images after deletion, observe the change of the image.

4. Interlaced, every column deletion K space data and displays its amplitude spectrum, by interlaced, after deleting every column K space data reconstruction of MR images, to observe the change of the image.

5. By matrix operations statement to remove high ? K space
