摘要：

A method of generating an enhanced receive signal from a piezoelectric ultrasound transduceris described. The method comprises providing a piezoelectric ultrasound transducercomprising a piezoelectric element operable in flexural mode, receiving a acousticsignal by the piezoelectric element, applying a DC bias to the piezoelectric elementprior to receiving the acoustic signal and/or concurrently with receiving theacoustic signal, and generating an enhanced receive signal from the piezoelectric elementas a result of receiving the acoustic signal by the piezoelectric element. pMUT-basedimaging probes using the above method are also described.
