Hello,

I would like to apply a 2D-3D registration and was wondering if there is any extensions within 3D Slicer that can do this? Our case is to register a 2D image (e.g. 2D cerebral angiograms to a 3D model) to a 3D model (segmented from 3D volume).

This paper is for context of what I am hoping for:

Many thanks,
