1. A system for scaling radiographic patient imaging comprising:
a processor unit;
a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for
obtaining an overlap two-dimensional rendering of a non-patient three-dimensional bone model and a radiographic patient image of a patient bone,
scaling the radiographic patient image by a scale factor using a scale marker in the radiographic patient image,
generating a three-dimensional bone model representative of the patient bone by projecting the overlap two-dimensional rendering of the non-patient three-dimensional bone model on the radiographic patient image of the patient bone, and
outputting the three-dimensional bone model representative of the patient bone.
