Matlab DICOM切片 [英] Matlab DICOM Slices

问题描述

我在matlab中将DICOM图像作为矩阵加载。我的问题是，如何在每个正交方向上显示该图像的特定切片？

I have a DICOM image loaded as a matrix in matlab. My question is, how do I show specific slices of that image in each orthogonal direction?

与位置100处的视图切片x类似，y = 0，z = 0

Like view slice x at position 100, y=0, z=0

推荐答案

如果您的矩阵是M，并且有d维（3，或者你有什么）并且你想要绘制1-D然后是其中一个维度的切片：

If your matrix is M, and has d dimensions (3, or what have you) and you want to plot a 1-D "slice" of one of the dimensions then:

  plot(squeeze(M(n1,n2, ...,:,...));

其中n1，n2，...是维x的位置， y，...你要切片的地方，而操作符（:)是你要绘制的尺寸。

where n1,n2,... are the positions of dimension x,y,... where you want to slice, and the operator (:) is the dimension you want to plot.

例如，给定5维矩阵M = rand（10,10,10,10,10），让我们围绕某些点切割第4维（x = n1，y = n2等等）

for example, given a 5 dimensional matrix M=rand(10,10,10,10,10), lets slice the 4-th dimension around some points (x=n1, y=n2, etc...)

   M=rand(10,10,10,10,10);
   n1=4; n2=7; n3=3; n5=5; 
   plot(squeeze(M(n1,n2, n3, :, n5)));

如果切片是2-D然后你可以使用imshow或imagesc来显示2-D切片，例如显示2-n和4 -th dimension：

If the slice is 2-D then you can use imshow or imagesc to show the 2-D slice, for example showing the 2-nd and 4-th dimension:

 imagesc(squeeze(M(n1,:,n3,:,n5)))
