Multimodal optoacoustic imaging: methods and contrast materials.

Chem Soc Rev
Combining optoacoustics with other imaging techniques helps bring its powerful label-free functional readings and molecular sensitivity into precise anatomical context while providing an essential cross-validation against established imaging methods.

Optoacoustic Imaging in Inflammation. [PDF]

Biomedicines, 2021
Optoacoustic or photoacoustic imaging (OAI/PAI) is a technology which enables non-invasive visualization of laser-illuminated tissue by the detection of acoustic signals. The combination of “light in” and “sound out” offers unprecedented scalability with a high penetration depth and resolution.

Optoacoustic imaging of the skin [PDF]

Experimental Dermatology, 2021
AbstractOptoacoustic (OA, photoacoustic) imaging capitalizes on the synergistic combination of light excitation and ultrasound detection to empower biological and clinical investigations with rich optical contrast while effectively bridging the gap between micro and macroscopic imaging realms. State‐of‐the‐art OA embodiments consistently provide images

Photocontrollable Proteins for Optoacoustic Imaging [PDF]

Analytical Chemistry, 2019
Photocontrollable proteins revolutionized life-science imaging due to their contribution to subdiffraction-resolution optical microscopy. They might have yet another lasting impact on photo- or optoacoustic imaging (OA). OA combines optical contrast with ultrasound detection enabling high-resolution real-time in vivo imaging well-beyond the typical ...

Optical and Optoacoustic Imaging

, 2020
The present chapter summarizes progress with optical methods that go beyond human vision. The focus is on two particular technologies: fluorescence molecular imaging and optoacoustic (photoacoustic) imaging. The rationale for the selection of these two methods is that in contrast to optical microscopy techniques, both fluorescence and optoacoustic ...
