The topic of getting axis-aligned bounding boxes is discussed here:

> I created a segmentation with some segments and want to get an axis-aligned bounding box for each segment. As far as i know, with the segment statistics module we can compute oriented bounding boxes, but i couldn’t find an option to get axis-aligned bounding boxes. I tried to get the segments as numpy arrays and use numpy functions to find the required values as suggested [here](https://discourse.slicer.org/t/python-script-to-get-axis-aligned-bounding-box/26227/5). But since i rotated the segments before, the segments do not match with the original scalar volume anymore. Do I need t…
