Scalable photoacoustic tomography implementations accounting for the spatial impulse response of transducers
Trung-Thai Do, Paul Escande, Caroline Chaux +2
Iterative model-based reconstruction in photoacoustic tomography repeatedly applies the forward operator mapping the initial pressure to the transducer signals, and its adjoint. At…
Simultaneous 3D co-registered perfusion and oxygenation with ULM, photoacoustic imaging, and a planar matrix array
Léa Davenet, Jacques Battaglia, Franck Lager +6
Objective. Joint assessment of tissue oxygenation and microvascular perfusion could offer valuable insights into vascular function across a wide range of biomedical applications. M…
Motion rejection and spectral unmixing for accurate estimation of in vivo oxygen saturation using multispectral optoacoustic tomography
Mitradeep Sarkar, Mailyn Pérez-Liva, Gilles Renault +2
Multispectral Optoacoustic Tomography (MSOT) uniquely enables spatial mapping in high resolution of oxygen saturation (SO), with potential applications in studying pathological…
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…
High contrast and resolution 3-D ultrasonography with a clinical linear transducer array scanned in a rotate-translate geometry
Théotim Lucas, Isabelle Quidu, S. Lori Bridal +1
We propose a novel solution for volumetric ultrasound imaging using single-side access 3-D synthetic-aperture scanning of a clinical linear array. This solution is based on an adva…
Calibrated photoacoustic spectrometer based on a conventional imaging system for in vitro characterization of contrast agents
Théotim Lucas, Mitradeep Sarkar, Yoann Atlas +4
Photoacoustic (PA) imaging systems are spreading in the biomedical community, and the de-velopment of new PA contrast agents is an active area of research. However, PA contrast age…
Topological transformations of speckles

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…
Anisotropic super-attenuation of capillary waves on driven glass interfaces
Bruno Bresson, Coralie Brun, Xavier Buet +11
Metrological AFM measurements are performed on the silica glass interfaces of photonic band-gap fibres and hollow capillaries. The freezing of attenuated out-of-equilibrium capilla…
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-…
