Abstract
Super-resolution ultrasound imaging has been so
far achieved in 3-D by mechanically scanning a volume with
a linear probe, by co-aligning multiple linear probes, by using
multiplexed 3-D clinical ultrasound systems, or by using 3-
D ultrasound research systems. In this study, a 2-D sparse
array was designed with 512 elements according to a density-
tapered 2-D spiral layout and optimized to reduce the sidelobes
of the transmitted beam profile. High frame rate volumetric
imaging with compounded plane waves was performed using
two synchronized ULA-OP256 systems. Localization-based 3-D
super-resolution images of two touching sub-wavelength tubes
were generated from a 120 second acquisition.
