Patent ID: 8073230

Claim:
A method for generating images for identifying diseases, the method comprising: receiving a first digital radiography (DR) X-ray image of at least a portion of a body of a patient; receiving a second DR X-ray image of the at least a portion of a body of a patient, the first X-ray image being captured at a different energy level than the second DR X-ray image; determining common control point locations for both the first and second DR X-ray images; generating an optimized DR X-ray image by moving portions of a selected one of the first and second DR X-ray images with its associated control points to locations that correspond to similar portions of the other of the first and second DR X-ray images; applying deformable transformation to one of the first and second DR X-ray images; and performing a log subtraction on the first and second DR X-ray image to generate a dual-energy digital radiography (DEDR) image.
