MATLAB: Saving a slice through volumetric data to an image [duplicate]

Question

This question already has answers here:

Extract arbitrarily rotated plane of data from 3D array as 2D array (2 answers)

Closed 8 years ago.

I have a 3D stack of bwlabeln'ed data (128 by 128 by 128). Is there a way to cut a slice through it (as in MATLAB slice(...)) and save the resulting image to a matrix?

Thanks in advance!

Answer 1

the function that may be of use is: http://www.mathworks.com/matlabcentral/fileexchange/32032-extract-slice-from-volume

Answer 2

What kind of slice? Along one dimension e.g. z=5 you can use M(:,:,5). For diagonal slices you have to use some advanced method (interpolation).
