Electrical resistance tomography method has been applied to the real-time measurement of cross sectional distribution of the erythrocyte sedimentation by measuring the electrical properties of blood. The electrical conductivity distribution was observed at three distinct planes from top to bottom of a container. In the experiments conducted with bovine blood, the average relative conductivity increased at the top and middle of a container with time while the average conductivity decreased at the bottom of the container. Moreover, the distribution of the conductivity at the middle of the container was peculiar. The conductivity was lower in the center of the cylinder, and gradual increment was observed towards the cylinder wall. The conductivity values were then interpreted in terms of concentration and orientation of the red blood cells based on Maxwell-Fricke equation. The concentration variation and different orientation of the red blood cells at different planes from top to bottom are expected to shed light on the mechanism of erythrocytes sedimentation.
