Hello, Rudolf & Andras.

I would be regularly cropping (in the **Crop Volume** module) and volume rendering according to my current ‘workflow’. I don’t think I would say “often”, though: it would generally be once per CT scan. This is for the purposes of _segmentation_, specifically:

- reducing the volume to be segmented (cutting computational load, and making it easier to see what’s going on); and
- improving the sampling properties (resolution & aspect ratio of voxels), as per the advice below.

On the other hand I do often use the cropping within the **Volume Rendering** module purely for visualisation. AFAIK, the functionality in that module is not able to restrict the voxels being segmented, nor resample. Did I miss something?
