Biomedical photoacoustic imaging [PDF]
Interface Focus, 2011 Photoacoustic (PA) imaging, also called optoacoustic imaging, is a new biomedical imaging modality based on the use of laser-generated ultrasound that has emerged over the last decade. It is a hybrid modality, combining the high-contrast and spectroscopic-based specificity of optical imaging with the high spatial resolution of ultrasound ...

Photoacoustic Resonance Imaging
IEEE Journal of Selected Topics in Quantum Electronics, 2019 In this paper, a new imaging modality, named photoacoustic resonance imaging (PARI), is proposed and experimentally demonstrated. Being distinct from conventional single nanosecond laser pulse induced wideband PA signal, the proposed PARI method utilizes multiburst modulated laser source to induce PA resonant signal with enhanced signal strength and ...

Advanced Therapeutics, EarlyView.The graphical abstract illustrates the combined effect of PTT and PDT using metal‐organic frameworks (MOFs) in a cancer treatment model. Tumor‐bearing mice are irradiated with different laser lights, which activate the MOF nanoparticles within cancer cells. The MOFs produce reactive oxygen species through PDT, while PTT elevates the temperature to kill

Brain‐Wide Spatiotemporally Distinct Traveling Waves Drive Anxiety‐Like Behaviors in Mice
Advanced Science, EarlyView.J.Liu et al. reveal the complete propagation dynamics of cortical traveling waves, from local circuitry initiation to long‐range propagation, and identify their functional relevance in modulating anxiety‐like behaviors and underlying cellular neuroplasticity in mice.

Prospects of photoacoustic tomography
Medical Physics, 2008 Commercially available high‐resolution three‐dimensional optical imaging modalities—including confocal microscopy, two‐photon microscopy, and optical coherence tomography—have fundamentally impacted biomedicine. Unfortunately, such tools cannot penetrate biological tissue deeper than the optical transport mean free path( in the skin).
