Abstract:
1. A method for locating a region of interest within a subject, the method comprising: acquiring planar nuclear medicine (NM) images of a subject from an NM system, the planar NM images including at least one identified region of interest; acquiring a three-dimensional (3D) x-ray Computed Tomography (CT) volume image of the subject from an x-ray CT system; and locating the at least one identified region of interest within the 3D CT volume image using the planar NM images, wherein locating the at least one identified region of interest comprises determining a two-dimensional location of the at least one identified region of interest and a brightness value of the at least one identified region of interest at the determined two-dimensional location in the planar NM images, calculating a brightness ratio, and determining, using a depth profile, a depth of the at least one identified region of interest within the subject using the brightness ratio.
