Popis: Inline phase tomography using synchrotron radiation with sub-micrometer voxel sizes is nowadays the gold standard for investigation of soft and hard tissues with micron resolution. Recent developments on detectors and X-ray sources allow the transfer of the technique into laboratory environment. For the comparison of three manufacturers, we performed microtomography with advanced laboratory microtomography devices with micron resolution on a porcine nerve, a zebrafish embryo and a historic human tooth. These data sets were also compared with data acquired at the ANATOMIX beamline at Synchrotron Soleil and the TOMCAT beamline at SLS. For the lab-based experiments following scanners were chosen: Skyscan 2214 (Bruker-microCT, Kontich, Belgium), Xradia 620 Versa (Zeiss, Oberkochen, Germany) and a prototype with a MetalJet X-ray source from Exillum from the company Exciscope (Stockholm, Sweden). All devices contained detectors including X-ray optics.
