Frequency wavelength multiplexed optoacoustic tomography
Optoacoustic imaging is mostly performed in the time domain. Here the authors demonstrate frequency wavelength multiplexed optoacoustic tomography that can operate at multiple wavelengths simultaneously and offers signal-to-noise ratio advantages over ...

Optoacoustic imaging of an animal model of prostate cancer [PDF]
Prostate cancer is currently the most common cancer among Canadian men. Due to an increase in public awareness and screening, prostate cancer is being detected at earlier stages and in much younger men.

Clutter elimination for deep clinical optoacoustic imaging using localised vibration tagging (LOVIT) [PDF]
This paper investigates a novel method which allows clutter elimination in deep optoacoustic imaging. Clutter significantly limits imaging depth in clinical optoacoustic imaging, when irradiation optics and ultrasound detector are integrated in a ...

Imaging of blood flow and oxygen state with a multi-segment optoacoustic ultrasound array
Changes in hemodynamic parameters are directly linked to biological function and physiological activity. Characterization of hemodynamics is commonly performed by Doppler ultrasound, which provides accurate measurements of blood flow velocity.

In vitro optoacoustic flow cytometry with light scattering referencing
Morphological and functional optoacoustic imaging is enhanced by dedicated transgene reporters, in analogy to fluorescence methods. The development of optoacoustic reporters using protein engineering and directed evolution would be accelerated by high ...

Capsule optoacoustic endoscopy for esophageal imaging [PDF]
AbstractDetection and monitoring of esophageal cancer severity require an imaging technique sensitive enough to detect early pathological changes in the esophagus and capable of analyzing the esophagus over 360 °in a non‐invasive manner. Optoacoustic endoscopy (COE) has been shown to resolve superficial vascular structure of the esophageal lumen in ...
