发帖数: 173 | 1 I have some image data of a mouse brain. The data consist of 256 slices and
each slice is a 256*256 grid. I can use imagesc to plot one slice at a time.
Could anyone tell me how to plot all slices simultaneously in the 3d space?
Any input will be appreciated. |

direction.
If you use 3D functions, you only get surface, not slices.
My 2 cents. May not be 100% correct.

option 2: slice
参考以前有一个关于显示人脑MRI的demo。新版本的Imgaing processing toolbox里好
像没了，但是网上搜得到。
最终建议，用专业的visualization 软件，比如Avizo(Amira)来显示。Matlab有时候X,
Y坐标位置会互换。具体讲就是用isosurface和plot3画出来的位置不一样。要想精确控
制，要先算isosurface的vertex和face，然后手工呼唤vertex里前两列坐标。

: I do the following.
: Save the 3D matrix as a vtk file, using the code in this webpage:

: open the vtk file with paraview.
