Volumetric and Simultaneous Photoacoustic and Ultrasound Imaging with a Conventional Linear Array in a Multiview Scanning Scheme

Clément Linger, Yoann Atlas, Remy Winter +5

Volumetric, multimodal imaging with precise spatial and temporal co-registration can provide valuable and complementary information for diagnosis and monitoring. Considerable resea…

Topological transformations of speckles

Jerome Gateau, Ferdinand Claude, Gilles Tessier +1

Deterministic control of coherent random light is highly important for information transmission through complex media. However, only a few simple speckle transformations can be ach…

Complementary Speckle Patterns : deterministic interchange of intrinsic vortices and maxima through Scattering Media

Jérôme Gateau, Hervé Rigneault, Marc Guillon

Intensity minima and maxima of speckle patterns obtained behind a diffuser are experimentally interchanged by applying a spiral phase delay of charge to the impinging coher…

Super-resolution photoacoustic fluctuation imaging with multiple speckle illumination

Thomas Chaigne, Jérôme Gateau, Marc Allain +4

In deep tissue photoacoustic imaging, the spatial resolution is inherently limited by acoustic diffraction. Moreover, as the ultrasound attenuation increases with frequency, resolu…

Optical-resolution photoacoustic imaging through thick tissue with a thin capillary as a dual optical-in acoustic-out waveguide

Olivier Simandoux, Nicolino Stasio, Jerome Gateau +4

We demonstrate the ability to guide high-frequency photoacoustic waves through thick tissue with a water-filled silica-capillary (150 μm inner diameter and 30 mm long). An optical-…

Single-side access, isotropic resolution and multispectral 3D photoacoustic imaging with rotate-translate scanning of ultrasonic detector array

Jérôme Gateau, Marc Gesnik, Jean-Marie Chassot +1

Photoacoustic imaging can achieve high-resolution three-dimensional visualization of optical absorbers at penetration depths ~ 1 cm in biological tissues by detecting optically-ind…

Light Focusing and Two-Dimensional Imaging Through Scattering Media using the Photoacoustic Transmission-Matrix with an Ultrasound Array

Thomas Chaigne, Jerome Gateau, Ori Katz +2

We implement the photoacoustic transmission-matrix approach on a two-dimensional photoacoustic imaging system, using a 15 MHz linear ultrasound array. Using a black leaf skeleton a…

Improving Photoacoustic-guided Focusing in Scattering Media by Spectrally Filtered Detection

Thomas Chaigne, Ori Katz, Jérôme Gateau +3

We experimentally and numerically study the potential of photoacoustic-guiding for light focusing through scattering samples via wavefront-shaping and iterative optimization. We ex…

Influence of nanoscale temperature rises on photoacoustic generation: discrimination between optical absorbers based on nonlinear photoacoustics at high frequency

Oliver Simandoux, Amaury Prost, Jérôme Gâteau +1

In the thermoelastic regime, photoacoustic sensing of optical absorption relies on conversion from light to acoustic energy via the coefficient of thermal expansion β. In this work…

Improving visibility in photoacoustic imaging using dynamic speckle illumination

Jérôme Gateau, Thomas Chaigne, Ori Katz +2

In high-frequency photoacoustic imaging with uniform illumination, homogeneous photo-absorbing structures may be invisible because of their large size or limited-view issues. Here…
