The work extends previous x-ray imaging of biological cells in the simple in-line holography geometry to full three-dimensional reconstruction, based on a fast iterative phase reconstruction algorithm which circumvents the usual twin-image problem. The sample is illuminated by the highly curved wave fronts emitted from a virtual quasi-point source with 10 nm cross section, realized by two crossed x-ray waveguides.

The new single-photon-counting pixel detector `Lambda' has been tested in a ptychographic imaging experiment on solar-cell nanowires using Kirkpatrick-Baez-focused 13.8keV X-rays. Taking advantage of the high count rate of the Lambda and dynamic range expansion by the semi-transparent central stop, a high-dynamic-range diffraction signal covering more than seven orders of magnitude has been recorded, which corresponds to a photon flux density of about 10(5)photonsnm(-2)s(-1) or a flux of approximate to 10(10)photonss(-1) on the sample. By comparison with data taken without the semi-transparent central stop, an increase in resolution by a factor of 3-4 is determined: from about 125nm to about 38nm for the nanowire and from about 83nm to about 21nm for the illuminating wavefield."],["dc.identifier.doi","10.1107/S2053273314014545"],["dc.identifier.gro","3142026"],["dc.identifier.isi","000344599300004"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12169"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/68463"],["dc.notes.intern","DOI Import GROB-352.6"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.eissn","2053-2733"],["dc.relation.eissn","1600-5724"],["dc.relation.issn","0108-7673"],["dc.relation.orgunit","Institut für Röntgenphysik"],["dc.relation.workinggroup","RG Salditt (Structure of Biomolecular Assemblies and X-Ray Physics)"],["dc.rights","Goescholar"],["dc.rights.uri","https://goedoc.uni-goettingen.de/licenses"],["dc.subject.gro","x-ray imaging"],["dc.title","Using invariom modelling to distinguish correct and incorrect central atoms in UPDATE 1\nUPDATE 1\nUPDATE 1\nUPDATE 1\nUPDATE 1\nUPDATE 1\nUPDATE 1\nUPDATE 1\nUPDATE 1\nUPDATE 1Lambda' based on the Medipix3 readout chip"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
