Abstract: A method of generating an enhanced receive signal from a piezoelectric ultrasound transducer is described. The method comprises providing a piezoelectric ultrasound transducer comprising a piezoelectric element operable in flexural mode, receiving a acoustic signal by the piezoelectric element, applying a DC bias to the piezoelectric element prior to receiving the acoustic signal and/or concurrently with receiving the acoustic signal, and generating an enhanced receive signal from the piezoelectric element as a result of receiving the acoustic signal by the piezoelectric element. pMUT-based imaging probes using the above method are also described.

Abstract: A new high speed method and apparatus for presenting display of images obtained from a volumetric scanner (19) in which multiple slices of object space are displayed simultaneously in real time thereby enabling a viewer to study relationships between various parts of the object. The slices are selectable by the viewer manipulating an icon on the display screen (15). Accordingly C-scans (C1, 2, 3) or B-scans (B1, 2) may be selected as well as I-scans (13) in which the scan plane has a selected orientation. Multiple I-scans may be selected and viewed in perspective so that the viewer has an impression of a three-dimensional display. Color and spectral doppler is incorporated with the scans to provide additional information of dynamic properties.
