High resolution x-ray microtomography has been established at the synchrotron radiation source at Daresbury Laboratory, U.K. A high precision mechanical stage with two translational and one rotational degree of freedom has been constructed, and fully characterised by mechanical metrology; overall precision is better than 0.5 μm. Collimation of the incident synchrotron radiation beam through a 4 pm aperture has been obtained, giving 2 μm overall spatial resolution. Results have been obtained using monochromatic radiation at both 1 angstrom and 0.37 angstrom wavelengths, on human bone fragments and on sintered alumina ceramics.
