Abstract
A method for loading a sample for imaging by an optical tomography system. A sample volume including at least one microscopic sample and a viscous fluid is coaxially loaded into a sample delivery tube. The sample volume is impelled through a focus cell into a capillary tube, where the capillary tube has a smaller crossectional area than the sample delivery tube, so that a reduced volume of the at least one microscopic sample and viscous fluid is constrained to a central region within the capillary tube.
