1. A method for visualization of 3D parametric data in a 2D image, the method comprising: receiving signals representing a set of 3D parametric data, the set of 3D parametric data including a plurality of voxels in 3D space each associated with at least one parametric value; receiving signals representing a set of 2D image data representing the 2D image, the set of 2D image data including information about a known camera position and a known camera orientation at which the 2D image was obtained; defining a viewing surface in the 3D space; identifying voxels of the set of 3D parametric data corresponding to the viewing surface; generating a graphical representation of the parametric values of the voxels corresponding to the viewing surface; determining a virtual 2D view of the viewing surface corresponding to the known camera position and the known camera orientation of the 2D image; and providing signals for displaying the 2D image using the set of 2D image data registered with the graphical representation of the parametric values of the voxels corresponding to the virtual 2D view.
