[Microcirculation stream modeling: hydromechanic and acoustic models].

The objective was to attempt mathematical modeling of ultrasonic scanning tissue section in order to discern signals from erythrocytes and leucocytes that is displayed as Doppler images. Hydromechanic and acoustic microcirculation models have been constructed for a 20 MHz ultrasonic sensor. Results of the modeling showed that ultrasonic blood cells differentiation will require complex analysis of amplitude and frequency parameters of echoed signal.
