Forward-viewing ring arrays can enable new applications in intravascular and intracardiac ultrasound. We have demonstrated full synthetic phased array volumetric ultrasound imaging using a forward-viewing CMUT ring array with 64 elements, in both the conventional (8 MHz) and collapse (19 MHz) regimes of operation. Measured SNR of an echo from a plane reflector at 5 mm is 29 dB for 8 MHz and 35 dB for 19 MHz. The 6-dB axial and lateral resolutions for the B-scan of the wire target is 189 µm anddoi:10.1109/ultsym.2005.1602968 fatcat:fl54sju6dbcx3mthjn7tnaiyzy
