Abstract
A method for identifying implanted reconstructive prosthetic devices comprising obtaining a digital radiographic image of a prosthetic implant that has been implanted in a person or animal for which the manufacturer and/or model is unknown; allowing a user to enter into a computer metadata relating to the implant for use as metadata feature values; cleaning up the unknown implant image; rotating, flipping and/or scaling the unknown implant image; extracting features from the unknown implant image according to one or more feature extraction algorithms; and comparing the metadata and extracted feature values for the unknown implant image to feature values for other implant images according to a comparison algorithm to create an overall likelihood score for each of the other implant images.
