Mayo S, Stevenson A, Wilkins S
Materials (Basel)
. 2017 Aug;
5(5):937-965.
PMID: 28817018
X-ray phase-contrast imaging and tomography make use of the refraction of X-rays by the sample in image formation. This provides considerable additional information in the image compared to conventional X-ray...

. 2012 Aug;
19(Pt 5):728-50.
PMID: 22898953
The first monochromatic X-ray tomography experiments conducted at the Imaging and Medical beamline of the Australian Synchrotron are reported. The sample was a phantom comprising nylon line, Al wire and...

. 2009 Jun;
14(17):7889-94.
PMID: 19529156
The X-ray ultramicroscope (XuM), based on using a scanning electron microscope as host, provides a new approach to X-ray projection microscopy. The right-angle-type integrated sample cells described here expand the...

Opt Express
. 2008 Jun;
16(5):3223-41.
PMID: 18542410
Simple analytical expressions are derived for the spatial resolution, contrast and signal-to-noise in X-ray projection images of a generic phase edge. The obtained expressions take into account the maximum phase...

J Opt Soc Am A Opt Image Sci Vis
. 2007 Jul;
24(8):2230-41.
PMID: 17621326
Optical systems capable of three-dimensional transmission imaging are considered; these systems employ a conventional tomographic setup with an added linear shift-invariant optical system between the sample and the detector. A...

. 2006 Feb;
23(1):34-42.
PMID: 16478058
Effects of incident illumination on phase-contrast images obtained by means of free-space propagation are investigated under the "transport-of-intensity" approximation. Analytical expressions for image intensity distribution are derived in the cases...

. 2004 May;
43(12):2418-30.
PMID: 15119611
The first Born and Rytov approximations of scattering theory are introduced in their less familiar near-field versions. Two algorithms for phase retrieval based on these approximations are then described. It...

. 2003 Dec;
42(32):6488-94.
PMID: 14650491
A new method for deconvolution of one-dimensional and multidimensional data is suggested. The proposed algorithm is local in the sense that the deconvolved data at a given point depend only...
