Abstract

Contrast-enhanced ultrasound (CEUS) imaging has great potential for use in many new ultrasound clinical applications. We recently proposed a novel CEUS imaging sequence, Hadamard-encoded multi-pulses (HEM), to improve the signal-to-noise (SNR) and contrast-to-tissue ratio (CTR) as compared to other classic CEUS methods. HEM increases microbubble responses by using longer coded transmit pulses and the fast polarity change between coded pulses. In this study, we propose to combine the HEM pulse with multiplane wave (MW) imaging technique to further improve CEUS imaging SNR and CNR. During MW-HEM transmissions, the microbubbles undergo multiple fast pulse polarity changes, leading to significantly improved microbubble nonlinear responses, and thus further enhanced SNR and CTR as compared to HEM alone or other CEUS sequences. This improvement may facilitate more robust CEUS imaging for deep abdominal organs and the heart.
