对比增强超声（CEUS）成像在许多新的超声临床应用中具有巨大的潜力。我们最近提出了一种新的CEUS成像序列，阿达玛编码的多脉冲（HEM），以提高信噪比（SNR）和对比度组织比（CTR）相比，其他经典的CEUS方法。HEM通过使用更长的编码发射脉冲和编码脉冲之间的快速极性变化来增加微泡响应。在本研究中，我们提出联合收割机将HEM脉冲与多平面波（MW）成像技术相结合，以进一步提高CEUS成像信噪比和CNR。在MW-HEM传输期间，微泡经历多个快速脉冲极性变化，导致显著改善的微泡非线性响应，并且因此与单独的HEM或其他CEUS序列相比进一步增强了SNR和CTR。这一改进可能有助于腹部深部器官和心脏的更稳健的CEUS成像。
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.
