Method and system for three-dimensional imaging in a non-calibrated geometry

An image processing system comprising:

• a computer, wherein the computer is configured to estimate an imaging geometry using at least one of fiducial markers or anatomical features represented in a plurality of projection images acquired through an imaging volume and to reconstruct a configurable volumetric representation of some or all of the imaging volume using the estimated imaging geometry, wherein the act of reconstructing accounts for one or more geometry dependent factors.
