A system for combining electromagnetic position and orientation tracking with magnetic resonance scanner is provided. In this regard, a representative method involving forward collimation of X-rays includes: emitting X-rays from a housing in which an X-ray source is mounted; collimating the X-rays downstream of the housing; and directing the collimated X-rays at a target. Then, using the first, second, third and fourth spectral data, colorimetric value data of the printed object in a given observational environment is calculated.
