The development of ultrafast ultrasound imaging brings great opportunities to improve imaging technologies such as shear wave elastography and ultrafast Doppler imaging. In ultrafast imaging, there are trade-offs among image signal-to-noise ratio (SNR), resolution, and the high frame rate. Multiplane wave (MW) imaging is proposed to solve this tradeoff by encoding multiple plane waves with positive/negative...
Contrast enhanced ultrasound (CEUS) imaging offers great opportunities for new ultrasound applications by improving the contrast between blood and tissue using microbubbles. However, the low signal-to-noise ratio (SNR) due to the low mechanical index (MI) requirement can be an issue in practice. Multiplane wave (MW) imaging is a technique recently proposed to increase the SNR for compounding plane...
Hadamard encoded Synthetic transmit aperture (H-STA) ultrasound imaging was proposed to provide RF signals with high signal-to-noise ratio (SNR). In this paper, the Hadamard encoded transmission was applied to designing a low-cost ultrasound imaging system by reducing the number of receiving channels and eliminating the delay circuit for transmission. However, reducing the receiving channels compromised...
