Claim:
1. A method for performing image mapping for computer tomography, the method comprising: generating a reference image based on a pre-stored reference data and a verification image corresponding to an imaging subject; displaying the reference image proximate to the verification image in an on-screen graphical display; receiving, a user input corresponding to a position within the on-screen graphical display, the user input being indicative of a direction within the reference image; in response to receiving the user input indicative of the direction, dynamically selecting an algorithm from a plurality of digitally reconstructed radiograph (DRR) generating algorithms based on the direction indicated by the user input; generating a DRR corresponding to the direction indicated by the user input from the pre-stored reference data with the dynamically selected algorithm, the DRR having a first resolution; identifying a plurality of structures in the DRR and a plurality of edges surrounding the plurality of structures; rendering a portion of the DRR within a threshold distance of the plurality of edges surrounding the identified plurality of structures in a second resolution being a different resolution than the first resolution; and incorporating the portion with the second resolution into the DRR.
