First Claim
1. A medical imaging system for locating tumors in tissue surrounding an anatomical portion of the human body subject to investigation for primary lesions, wherein the imaging system comprises:
- a single-photon limited angle tomographic imaging device for tomographic image acquisition and reconstruction to provide a first emission image including tissue surrounding the anatomical portion;
a digital radiography device including an X-ray generator, X-ray tube, and a digital X-ray detector operable to produce, via tomosynthesis, an X-ray transmission image of the anatomical portion and tissue thereabout; and
a single-photon nuclear imaging device for tomographic image acquisition and reconstruction to produce a second emission image of the anatomical portion and tissue previously viewed by the digital radiography device, wherein the first emission image, the transmission image and the second emission image combine to create two- and three-dimensional, co-registered image sets for a computer graphical display of the anatomical portion and tissue surrounding the anatomical portion.

Abstract
A medical imaging system locates tumors in tissue surrounding an anatomical portion of the human body subject to investigation for primary lesions. The imaging system comprises a single-photon limited angle tomographic imaging device to provide a first emission image including tissue surrounding the anatomical portion. In combination with the single photon limited angle tomographic imaging device, a digital x-ray device provides an x-ray transmission image of the anatomical portion and tissue thereabout. A third component of the imaging system is a single-photon nuclear imaging device for tomographic image acquisition and reconstruction to produce a second emission image of the anatomical portion and tissue previously viewed by the digital radiography device. Registration of the first emission image, the transmission image and the second emission leads to selection of two- and three-dimensional image sets of the anatomical portion and tissue surrounding the anatomical portion.
