Live 3D slicing and cropping

Dear all,

Im currently implementing OHIF at my universitys medical anatomy course and so far im very impressed!

Im wondering whether there is an option to slice or crop 3D rendered CT scans on the fly? E.g. have a Mip projection of a certain part of the scan and then open that up?
Is this something that is available already or via extension?

Cheers
Flo
