A Doppler ultrasound technique for measuring human milk flow.
The authors describe the development of a Doppler ultrasound flow transducer used in conjunction with a zero-crossing demodulator for breast milk flow measurement. The results of the preliminary evaluation in vitro are presented in the paper. The design is at present being minaturised in order to use the transducer for in vivo measurement.
