Abstract

The red blood cell (RBC) deformability was measured using laser-diffraction slit rheometer. The instrument consisted of a lase diode, step motor, a thermostated bob-cup measuring system, and a video camera attached to a microcomputer. The flow-rate and pressure drop measurements that were required for the operation of a slit rheometer were replaced with a single measurement of pressure variation with time. It was observed that elongation index as a measure of RBC deformability which was calculated from an isointensity curve in the diffraction pattern using an ellipse fitting program.
