Establishment of real‐time monitoring technique for blood viscosity during extracorporeal treatment is strongly desired. We have demonstrated that the red blood cell aggregation degree, which highly correlates with the blood viscosity, can be estimated by the microscopic observation of the red blood cell over a transparent blood circuit tube and the two‐dimensional correlation process executed between time different images. In this paper, for estimation precision improvement, a maximum likelihood design of correlation region based on calculation of local flow vector has been attempted.
