Low-power ultrasound imaging systems using time delay spectrometry

Ultrasound (US) imaging systems have undergone substantial miniaturization leading to many clinical applications that rely on batteries. However, current clinical US systems utilizing pulse-echo imaging require a high voltage and short duration transmit pulse along with electronics that operate in the MHz frequency range. We are investigating a novel imaging method that employs time-delay spectrometry (TDS) as an alternative to pulse-echo and...
