Paper Abstract

The use of x-ray microtomography to evaluate 3D volumes of bone has become wide spread with the introduction of numerous commercial systems intended for the examination of small animals and specimens. However, a consistent method for describing the spatial resolution has not been employed in characterizing the performance of these units. In this paper, we report the blur factors which contribute to a system's performance, methods to experimentally assess the performance of microtomography system components, and an experimental method to assess tomographic resolving power. By scanning a 1.5 mm diameter ruby sphere, the overall system resolving power of a classic microtomography system was measured to have a 98 micron FWHM of a determined plane spread function, while the FWHM for a contemporary system was determined to be 23 microns.
