Photoacoustic flow cytometry [PDF]
Methods, 2012 Conventional flow cytometry using scattering and fluorescent detection methods has been a fundamental tool of biological discoveries for many years. Invasive extraction of cells from a living organism, however, may lead to changes in cell properties and prevents the long-term study of cells in their native environment.

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 ...

Intravascular Photoacoustic Imaging [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2010 Intravascular photoacoustic (IVPA) imaging is a catheter-based, minimally invasive, imaging modality capable of providing high-resolution optical absorption map of the arterial wall. Integrated with intravascular ultrasound (IVUS) imaging, combined IVPA and IVUS imaging can be used to detect and characterize atherosclerotic plaques building up in the ...

Inverse Transport Theory of Photoacoustics
, 2009 We consider the reconstruction of optical parameters in a domain of interest from photoacoustic data. Photoacoustic tomography (PAT) radiates high frequency electromagnetic waves into the domain and measures acoustic signals emitted by the resulting ...

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 ...
