1. A calibration target apparatus for use with a radiographic image detector of an imaging system, the calibration target comprising:
a target frame securable to a radiographic image, the target frame defining an interior passage; and
a plurality of at least partially radiopaque markers coupled to the target frame and transversing the interior passage,
wherein the plurality of radiopaque markers partially obstruct passage of radiation through the internal passage of the frame.
