Abstract:
1. A method of processing image data from an imaging system for locating a plurality N of objects embedded in a body, comprising: receiving data for a first two-dimensional image of a region of interest of said body containing said plurality N of objects, said first two-dimensional image being obtained from a first imaging setting of said imaging system relative to said region of interest; receiving data for a second two-dimensional image of a region of interest of said body containing said plurality N of objects, said second two-dimensional image being obtained from a second imaging setting of said imaging system relative to said region of interest; receiving data for a third two-dimensional image of a region of interest of said body containing said plurality N of objects, said third two-dimensional image being obtained from a third imaging setting of said imaging system relative to said region of interest; determining two-dimensional positions for a first plurality of objects N determining two-dimensional positions for a second plurality of objects N determining two-dimensional positions for a third plurality of objects N calculating a cost associated with each of said first plurality of objects N eliminating some of said N calculating a cost associated with each of said n eliminating some of said n calculating three-dimensional positions of each of said plurality N of objects embedded in said region of interest of said body based on surviving matches of objects in each said two-dimensional image, wherein said first, second and third imaging settings all are different from each other.
