title = "An examination of phase retrieval algorithms as applied to phase contrast tomography using laboratory sources",
abstract = "Many objects relevant to materials science, biology and medicine are weakly absorbing to the hard energy x rays typically produced by laboratory sources. However, these samples can produce significant shifts in the phase of the x rays, which can be exploited using in-line phase contrast. This paper describes the work carried out to optimize phase contrast tomography using a polychromatic laboratory source. A variety of different phase retrieval algorithms are compared for two samples, one of uniformly low absorption contrast, the other comprising soft and hard materials, with a view to establishing basic guidelines for laboratory phase contrast tomography. {\textcopyright} 2010 Copyright SPIE - The International Society for Optical Engineering.",
