Check out our new paper led by YiRang Shin where she developed a novel way of conducting nonlinear contrast microbubble imaging (in the context of ULM) with high imaging volume rate. We found nonlinear imaging (mostly amplitude modulation) particularly helpful for extracting slowly moving microbubbles that are easily "buried" by moving tissues and rejected by clutter filters like SVD. Our method was tailored to the multiplexed 32x32 element Vermon matrix array operated by a Verasonics® 256-channel system. A microbubble location based motion correction algorithm was also proposed to solve the issue of "missing tissues" with nonlinear harmonic imaging.
