[ITK-users] Get Z (mm) on a mha volume

[Dženan Zukić]

Hi Matias,

in order to get "Z" value of a specific slice, you need to get it from tag
Image Position (Patient) (0020,0032).

If you read it into a 3D volume you can get "Z" value by using
image->TransformIndexToPhysicalPoint
<https://itk.org/Doxygen/html/classitk_1_1ImageBase.html#ab003313ba1a078d89a832dc0a35d2efa>
by
providing e.g. index [0,0,slice]. Caveat: the 3D reader assumes equidistant
spacing between slices, by examining distance between slices 0 and 1. In
case of non-constant Z spacing this method will likely produce wrong result.

Regards
