Accurate effective atomic number determination with polychromatic grating-based phase-contrast computed tomography.

Optics express

Birnbacher L, Willner M, Marschner M, Pfeiffer D, Pfeiffer F, Herzen J.
PMID: 30114766
Opt Express. 2018 Jun 11;26(12):15153-15166. doi: 10.1364/OE.26.015153.

The demand for quantitative medical imaging is increasing in the ongoing digitalization. Conventional computed tomography (CT) is energy-dependent and therefore of limited comparability. In contrast, dual-energy CT (DECT) allows for the determination of absolute image contrast quantities, namely the...

Grating-based phase-contrast computed tomography (GBPC-CT) enables increased soft tissue differentiation, but often suffers from streak artifacts when performing high-sensitivity GBPC-CT of biomedical samples. Current GBPC-CT setups consist of one-dimensional gratings and hence allow to measure only the differential phase-contrast...
