Quantitative phase-contrast tomography using polychromatic radiation

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


We discuss theoretical, experimental and numerical aspects of several new techniques for quantitative phase-contrast tomography using, for example, unfiltered radiation from a polychromatic X-ray microfocus source. The proposed algorithms allow one to reconstruct the three-dimensional distribution of complex refractive index in a sample consisting of one or more constituent materials, given one or more projection images per view angle. If the sample is weakly absorbing or consists predominantly...[Show more]
