Patent ID: 8712008

Claim:
An apparatus for generating an image of an object of interest, the apparatus comprising: a processor; and a computer-readable storage medium storing instructions that, when executed, cause the processor to perform operations comprising: accessing a volumetric image of a space, the space including an object of interest and another object, the volumetric image comprising multiple regions with at least one region representing the object of interest and at least one region representing the other object; accessing a two-dimensional radiograph comprising data representing the object of interest and data representing the other object; identifying, in the volumetric image, a region representing the object of interest; generating a de-objectified volumetric image by disregarding the identified region; and removing from the two-dimensional radiograph a two-dimensional representation of the other object that is derived from the de-objectified volumetric image to generate a two-dimensional image of the object of interest.
