Research Abstract

Microfluidic circulation with suspension of micro-molecules was observed by high speed CCD camera. High frequency ultrasound of 120 MHz was emitted to the model and the spectrum of the reflected ultrasound was analyzed by neural network. The dimensions and structures of the micro-molecules were evaluated by the method. Application of the blood flow or lymph flow to the method in living subjects may realize in vivo “sono-cytometry" in the near future.
