This paper introduces a sparse deconvolution framework to enhance resolution in ultrafast power Doppler ultrasound imaging, improving microvascular and functional brain imaging without contrast agents.

SVD-SN2N improves denoising of SVD-filtered ultrasound images by converting multiplicative speckle to additive noise, enhancing SNR and vessel resolution without requiring clean references or raw data.

This paper introduces MS-SVD, a multi-stage SVD framework for ultrafast CEUS imaging that improves microbubble detection and vascular contrast by separating nonlinear signals from tissue clutter.

The paper examines brain network plasticity during neuropathic pain onset and maintenance in mice, finding stable connectivity during maintenance and changes at onset and post-surgery.

This paper introduces HAM-SVD, a method for ultrafast ultrasound imaging of gas vesicles that improves signal-to-background ratio compared to existing techniques.

This study uses functional ultrasound imaging to show that cerebral blood volume changes in rats correlate with speed and spatial features during navigation, revealing a hemodynamic signature of exploratory behavior.

This paper introduces nonlinear singular value decomposition beamforming for ultrasound imaging of gas vesicles, achieving comparable sensitivity to existing methods with fewer pulse transmissions and improved signal-to-background ratio.

PhysiofUS uses ultrafast ultrasound to automatically detect heart and breathing rates from tissue motion in rodents and human neonates, validated against gold-standard electrodes.

This study introduces a novel transcranial whole-brain fUS and ULM technique in mice using multilinear probes, revealing vessel-level dependencies in neurovascular responses.

This paper develops a non-invasive biomarker using functional ultrasound imaging to quantify myelin loss in a mouse model of multiple sclerosis.

This study uses functional ultrasound imaging in awake mice to reveal brain state dynamics during cold perception, identifying new patterns of interregional connectivity and affective responses.
