Claim:
1. An apparatus, comprising: a coring tool to obtain a core sample from a geological formation; an X-ray generator to emit an X-ray beam substantially perpendicular to a longitudinal axis of the core sample; an X-ray detector to detect the X-ray beam through the core sample to determine a characteristic of the core sample, wherein the X-ray generator, the X-ray detector, or both are configured to be moved to different angular positions with respect to the longitudinal axis, azimuthally, or laterally to generate an image of the core sample in three dimensions; a piston to convey the core sample through a passageway within the coring tool; and a calibration plug affixed to a face of the piston to move through the passageway between the X-ray generator and the X-ray detector as the piston advances, wherein the calibration plug does not comprise core samples from the geological formation.
