Paper Abstract

Proper selection of modern key components allows eliminating most artifacts in micro-CT and nano-CT systems already during data acquisition. X-ray cameras with direct photon detection allow avoiding ring artifacts. Newly developed fully depleted CCD sensors show an energy response similar to traditional cameras with a thin scintillator, but without any geometrical distortions and flashes from x-ray photons penetrating through the fiber optics. Air-bearing rotation stages and piezo-positioning minimizes mechanical inaccuracies in acquiring angular projections. Beam hardening can be eliminated by energy-selective photon counting imaging.
