Given an image volume and a segmentation, is there a way to get image statistics on individual slices along an axis? In particular, I’m looking for mean image intensities within 2D segmentations in multiple Axial views.

Have you tried the **Segment Statistics** module of the latest nightly version?

I have, yes. However, if I create a 3D segmentation, it appears that what’s produced is a set of statistics for the full 3D segmentation, rather than individual slices along an axis. Is there a way to get (Axial) slice-by-slice statistics, without creating a separate segment for every slice?

This is a very specialized requirement that you have to implement a simple script for. Probably the easiest is to export segmentation to labelmap volume and do compute statistics using numpy. In numpy it’s very easy to get a single slice of a volume, apply a mask, and compute mean.

Ok, thanks, I’ll try it that way.

Dear Professor Michael Schumaker:
Did you completed such a statistics?
