Synchrotron x-ray computed microtomography (CMT) can be used to make nondestructive tomographic sections with spatial resolutions of a few micrometers. This resolution presents possibilities for study of soil-fluid interactions on a spatial scale hitherto unreachable. Details of a CMT apparatus in operation at the Brookhaven National Synchrotron Light Source X26 beam line are presented and prospects for future development at new synchroton facilities are considered. Several investigations of test systems have been made and results for wet and dry samples of glass beads and sand samples are given to show the power of the system.
