1. A method for correcting inaccuracies in a three-dimensional (3D) rendered volume of an object due to deviations between an actual scanner translation speed and an expected scanner translation speed, the method comprising:
placing a pre-measured reference adjacent to the object which is being scanned so that the pre-measured reference and the object are in the same scan field;
scanning the object and the pre-measured reference so that the object and the pre-measured reference are both incorporated in a 3D rendered volume produced through scanning;
isolating the 3D rendered volume of the pre-measured reference from the 3D rendered volume of the object and the pre-measured reference;
comparing the 3D rendered volume of the pre-measured reference against the 3D volume of the true pre-measured reference and generating a correction map indicative of how the 3D rendered volume of the pre-measured reference should be adjusted so as to correct inaccuracies in the 3D rendered volume of the pre-measured reference; and
using the correction map to adjust the 3D rendered volume of the object.
