Systems and methods are provided for processing medical images to generate information useful for planning or guiding revision surgeries, designing implants for use in revisions surgeries, or generally evaluating the bone architecture of a subject. The medical images may be x-ray images, such as those acquired with a computed tomography (“CT”) system, magnetic resonance images, such as those acquired with a magnetic resonance imaging (“MRI”) system, or ultrasound images, such as those acquired with an ultrasound imaging system. The images can also be fused together, or otherwise combined, to produce combined images that enhance the depiction of an instrument or implant in the subject relative to the uncombined images.
