Photoacoustic and Ultrasonic Imaging

This study examines how skin melanin pigmentation affects photoacoustic imaging and oximetry, finding overestimation of blood oxygen saturation in higher Fitzpatrick skin types.

The paper introduces a method to generate arbitrary photoacoustic wavefronts using optical holograms and laser pulses, demonstrating beam steering in four directions.

The paper uses PET and MSOT to observe hypoxia and increased spinal cord metabolism in tMCAO mice compared to sham-operated mice.

This paper demonstrates that photoacoustic imaging can non-invasively measure intestinal tissue oxygenation and motility in neonatal rats, showing its potential for assessing intestinal health in premature infants.

This paper demonstrates noninvasive transcranial MSOT angiography in a human volunteer and validates its anatomical alignment with MRI.

This paper develops a candle soot fiber optoacoustic emitter for high-precision neuromodulation, achieving tenfold higher efficiency than existing carbon-based emitters.

This paper introduces vfUSI, a platform for brain-wide functional ultrasound imaging in mice, enabling high-resolution analysis of circuit dynamics and neural activity.

The paper validates the focal specificity of transcranial functional photoacoustic voltage-sensitive dye imaging in rat hippocampus by correlating NMDA-evoked neural activity with glutamate release and EEG signals.

This paper introduces a miniaturized Fiber-Optoacoustic Converter for high spatial precision neural stimulation in mice, achieving submillimeter resolution in vivo.

This paper introduces gas vesicles as ultrasound contrast agents to enhance transcranial hemodynamic functional ultrasound imaging of mouse brain activity.
