Performance Assessment of Ultra-Wideband and Dual-Mode 1D CMUT Arrays for Acoustic Angiography
2022 IEEE INTERNATIONAL ULTRASONICS SYMPOSIUM (IEEE IUS).
author keywords: capacitive micromachined ultrasonic transducer; ultra-wideband; dual-mode; acoustic angiography; ultrasound handheld probe; contrast agent
TL;DR:
A custom 256-channel imaging probe with integrated low-noise amplifiers and supporting power circuitry is designed with a strong use case for the UWB and dual-mode CMUT arrays in acoustic angiography applications.

Implementation of a Novel 288-Element Dual-Frequency Array for Acoustic Angiography: In Vitro and In Vivo Characterization
IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, 68(8), 2657–2666.
author keywords: Imaging; Acoustics; Angiography; Transducers; Frequency measurement; Ultrasonic imaging; In vitro; Acoustic angiography; contrast agent; dual-frequency (DF); microbubbles; microvasculature; superharmonic
MeSH headings : Acoustics; Angiography; Contrast Media; Transducers; Ultrasonography
TL;DR:
This work presents a system for performing acoustic angiography with a novel dual-frequency DF transducer—a coaxially stacked DF array (DFA), and evaluates the system both in vitro and in vivo and demonstrates improvements in sensitivity and imaging depth up to 13.1 dB and 10 mm, respectively, compared with previous wobbler probes.

Superharmonic Ultrasound for Motion-Independent Localization Microscopy: Applications to Microvascular Imaging From Low to High Flow Rates
IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, 67(5), 957–967.
author keywords: Acoustic angiography (AA); angiogenesis; contrast agent; microbubble (MB); microvasculature; superharmonic imaging (SHI); ultrasound localization microscopy (ULM)
MeSH headings : Angiography; Animals; Female; Image Processing, Computer-Assisted / methods; Kidney / blood supply; Kidney / diagnostic imaging; Microscopy / methods; Microvessels / diagnostic imaging; Movement; Rats; Ultrasonography / methods
TL;DR:
Superharmonic imaging is applied to ULM and an average improvement in SNR of 10.3-dB in vitro when compared with the standard singular value decomposition filter approach and an increase inSNR at low flow from 5 to 16.5 dB.
