Human fetal diagnostic ultrasound exposimetry system

Research output: Contribution to journalConference articlepeer-review


Improvements that have been made to a unique human fetal diagnostic ultrasound exposimetry system which has been designed to measure acoustic pressure in situ with a 7-element linear array hydrophone during an obstetric ultrasound examination are discussed. The purpose of the exposimetry system is to develop a data base of fundamental ultrasound propagation properties for human tissue under in vivo conditions from which the ultrasound exposure, and possibly the ultrasound dose, can be estimated under normal clinical conditions. The improvements have increased the reliability of the recorded acoustic pressure waveform and provided the new capability of recording image from the diagnostic ultrasound system simultaneously with the acoustic pressure waveform.
