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 ...

Photoacoustic clinical imaging

Photoacoustics, 2019
Photoacoustic is an emerging biomedical imaging modality, which allows imaging optical absorbers in the tissue by acoustic detectors (light in - sound out). Such a technique has an immense potential for clinical translation since it allows high resolution, sufficient imaging depth, with diverse endogenous and exogenous contrast, and is free from ...

A Skull-Removed Chronic Cranial Window for Ultrasound and Photoacoustic Imaging of the Rodent Brain

Frontiers in Neuroscience, 2021
Ultrasound and photoacoustic imaging are emerging as powerful tools to study brain structures and functions. The skull introduces significant distortion and attenuation of the ultrasound signals deteriorating image quality.

Nanoparticles for photoacoustic imaging [PDF]

WIREs Nanomedicine and Nanobiotechnology, 2009
AbstractNanoparticles have been designed and applied as contrast enhancers in various optical imaging techniques, such as optical coherence tomography, fluorescence imaging, and optical reflectance microscopy. As an emerging hybrid imaging modality, photoacoustic imaging (PAI) has also benefited from the application of these nanoparticle‐based contrast

Super-resolution photoacoustic fluctuation imaging with multiple speckle illumination [PDF]

, 2015
In deep tissue photoacoustic imaging, the spatial resolution is inherently limited by acoustic diffraction. Moreover, as the ultrasound attenuation increases with frequency, resolution is often traded-off for penetration depth.

Clinical photoacoustic imaging platforms [PDF]

Biomedical Engineering Letters, 2018
Photoacoustic imaging (PAI) is a new promising medical imaging technology available for diagnosing and assessing various pathologies. PAI complements existing imaging modalities by providing information not currently available for diagnosing, e.g., oxygenation level of the underlying tissue.

Molecular Photoacoustic Imaging [PDF]

Bionatura, 2021
Medicine has gone through several challenges to make it much more accurate and thus prolong the human being's life. A large part of this challenge is diseased, so early detection can help carry out treatment on time. There is a technology that allows detecting an abnormality within the body without using an invasive method.
