ABSTRACT:
In a method and apparatus for scatter-glare correction in x-ray diagnostic images from a patient, a densitometric calibration phantom that reduces x-ray beam hardening effects. The calibration phantom is constructed from x-ray absorbing specks narrower than the x-ray aperture but thicker in the x-ray direction than the half-value thickness for diagnostic energy photons, the specks being aligned with the fan beams of x-rays from the x-ray source.
