Hello,
Given a 3D DCIOM image, how can I manually segment a part (e.g. tumour) of the image to save and do further processing on it?
Thanks,

You can use freehand masking slice-by-slice. See attached demo.

One more thing, the demo you provided masks only one region, what about multiple areas in an image that we need to be segmented from a single image in the same time?

So don't crop it. That is an optional part. You can just quit after you get the masked image. The masked image will be the same size as the original.
