One promising way to mitigate this is posing imaging as an inverse problem. Inverse problem-based imaging approaches can yield high image quality with few transmits, but existing methods require a very fine image grid and are not robust to changes in measurement model parameters. We present INverse grid-Free Estimation of Reflectivities (INFER), an off-grid and stochastic algorithm that finds a solution to the inverse scattering problem in ultrasound imaging. Our method jointly optimizes for the locations of the gridpoints, their reflectivities, and the speed of sound. This approach allows us to use fewer gridpoints than existing methods. At the same time it obtains 2-3x higher far field lateral resolution and 6-68% higher gCNR on in-vivo data, and it is robust to speed of sound changes of up to ±100m/s. The use of stochastic optimization enables solving for multiple transmissions simultaneously without increasing the required memory or computational load per iteration. We show that our method works on both phantom and in-vivo data and compares favorably against existing beamforming methods.

The angular spectrum (AS) method presents the most efficient algorithm for PAM, but it suffers from artifacts and low resolution due to the diffraction pattern of the imaging array. Data-adaptive beamformers suppress artifacts well, but their overwhelming computational complexity, more than two orders of magnitude higher than the classical time exposure acoustic (TEA) method, hinders their application in real-time. In this work, we introduce the cross-correlated AS method to address the challenge. This method is based on cross-correlating the AS back-propagated wave fields, in the frequency domain, measured by different apodized sub-apertures of the transducer array to provide the normalized correlation coefficient (NCC) matrix for artifacts suppression. We observed that the spatial pattern of NCC matrix is variable which can be utilized by the triple apodization with cross-correlation (TAX) with AS scheme, namely the AS-TAX method, for optimal artifacts suppression outcomes. Both the phantom and mouse tumor experiments showed that: 1) the AS-TAX method has comparable image quality as the data-adaptive beamformers, reducing the energy spread area by 34.8-65.0% and improving image signal-to-noise ratio by 10.6-14.4 dB compared to TEA; 2) it reduces the computational complexity by two orders of magnitude compared to TEA allowing millisecond-level image reconstruction speed with a parallel implementation; 3) it can well map microbubble cavitation activity of different status (stable or inertial).

This 3D monitoring capability is essential for detecting off-target cavitation events, particularly in at-risk structures and those occurring outside the plane of 2D imaging. In this work, we demonstrate that using row-column arrays (RCAs) for 3D passive acoustic mapping (PAM), which can be easily integrated to commercial ultrasound scanners compared to using hemispherical arrays or matrix arrays, represents a potent solution. For that, we propose the RCA-PAM method for image formation. This method deploys the angular spectrum (AS) method to back-propagate 3D harmonic wave fields using the passively received cavitation signals by the RCA's row and column apertures, respectively. Then, the 3D PAM volume is obtained by integrating the cross-spectrum of the two wave fields over selected bandwidth. To further reduce image artifacts, we combine AS with dual-apodization with cross-correlation (AS-DAX) for wave field propagation. Our experiments showed that, RCA-PAM achieved 0.04±0.07 mm source localization error and comparable image-quality as the ones reconstructed for the matrix array (same aperture size). We realized over 40 volumes/second reconstruction speed for a volume sized 128×128×250 voxels, using all frequency components in the RCA's working bandwidth. We also demonstrate the seamless combination of RCA-PAM and B-mode imaging using the same RCA for 3D monitoring of MB cavitation activity in a mouse tumor model.

Several super-resolution imaging techniques have been applied for coronary imaging; however, most only measure the coronary flow during the diastolic phase and have a long data acquisition time. To address these problems, this study proposes an adaptive frame selection approach for coronary vasculature imaging. In this approach, similar frames within cardiac cycles are selected using the sum of absolute difference (SAD) algorithm, and the coronary vasculature blood flow is calculated without using electrocardiographic gating data. Experiments were performed in mouse hearts through high-frequency ultrafast ultrasound imaging. After similar frames were selected from several cardiac cycles (one to five cycles), a singular value decomposition filter was applied to extract blood flow signals and obtain a dynamic coronary vasculature image, the accuracy of which was confirmed by measuring Doppler sonograms from the left coronary artery and arterioles. The conventional method (without SAD), in which only blood flow in the diastolic phase is calculated, was also conducted to enable a comparison in terms of measured vessel size and signal-to-noise ratio. The signal-to-noise ratio for the proposed approach were found to be 20.74 ± 1.62 dB, under the best parameter settings.
