We employed filters of 0.6-mm-thick tin and 0.1-mm-thick tungsten to generate high- and low-energy spectra from 120 kVp X-rays, respectively. Two filter-based DE- CBCT methodologies were tested: (i) alternative spectral switching and (ii) simultaneous beam splitting. ![]() ![]() We evaluated two dual-energy cone-beam computed tomography (DE- CBCT) methodologies for a bench-top micro- CBCT system to reduce metal artifacts on reconstructed images. ![]() Iramina, Hiraku Hamaguchi, Takumi Nakamura, Mitsuhiro Mizowaki, Takashi Kanno, Ikuo ![]() Metal artifact reduction by filter-based dual-energy cone-beam computed tomography on a bench-top micro- CBCT system: concept and demonstration.
