Generalized tomosynthesis for focusing on an arbitrary surface.
Previous implementations of tomosynthesis used reconstruction algorithms that generate planar tomograms where the structures in one plane are visualized and the structures out of the plane are blurred. In many applications, however, the structures of interest do not reside in a single plane and it is desirable to generalize the reconstruction algorithm to generate a tomogram focused on the structure itself. A procedure that allows such a reconstruction is described, and its usefulness in focusing on a three-dimensional object is demonstrated.
