Polychromatic cone­-beam phase­-contrast tomography

Myers, Glenn; Mayo, S.C.; Gureyev, Timur E; Paganin, David M; Wilkins, S.W.

Description

A method is presented for quantitative phase-contrast tomography using unfiltered radiation from a small polychromatic source. The three-dimensional distribution of complex refractive index in a monomorphous object is reconstructed given a single projection image per view angle. The reconstruction algorithm is achromatic and stable with respect to high-spatial-frequency noise, in contrast to conventional tomography. The density distribution in a test sample was accurately reconstructed from...[Show more]
