Final answer:
Removing even more low-energy x-ray photons through a filter at the aperture of the x-ray tube would result in an increase in the beam hardening artifact and a decrease in the partial volume artifact.
Step-by-step explanation:
Removing even more low-energy x-ray photons with a filter at the aperture of the x-ray tube would increase the beam hardening artifact and decrease the partial volume artifact.
Beam hardening artifact is caused by the preferential absorption of low-energy x-ray photons, resulting in an increase in the average energy of the x-ray beam. Removing more low-energy x-ray photons would reduce this artifact.
Partial volume artifact occurs when different structures with differing attenuation properties are imaged together, leading to blurring and image degradation. By removing more low-energy x-ray photons, the contrast in the image is increased, reducing the partial volume artifact.
