Scanned using a UHF29x transducer on a Vevo F2 LAZR-X system.

3D rendered high-resolution ultrasound (greyscale) and spectrally unmixed photoacoustic (red, blue and gold) image of a subcutaneous tumor showing nanoparticle distribution (yellow) as well as oxygenated (red) and deoxygenated (blue) hemoglobin signal.

In this parametric map of oxygen saturation in an orthotopic breast tumor, the breathed oxygen concentration is varied from 100% to 5% back to 100% and the resulting changes in sO₂ can be observed in different areas.

Note that the sO₂ in the tumor interior does not change appreciably during the breathed oxygen challenge, indicating impaired function of the vasculature there.

3D rendered coregistered ultrasound (greyscale) and photoacoustic (red) image of the mouse ear.  The photoacoustic signal is derived from the absorption of light by hemoglobin.

Non-linear contrast bolus perfusion into a subcutaneous tumor in a mouse. See Oncology images.

Co-registered 3D rendered ultrasound (greyscale) and color Doppler (red and blue) coronal image of a mouse brain during ligation of the right common carotid artery.  The red and blue color represent blood flow velocity and direction clearly showing impaired blood flow in the right hemisphere.

3D rendered photoacoustic image showing cerebral blood signal in the mouse brain.

3D rendered co-registered ultrasound (greyscale) and photoacoustic (red, white and teal) image showing a parametric map of oxygen saturation with red signals indicating higher sO₂ values.

High-resolution ultrasound (greyscale) and photoacoustic (red, white and blue) image of a long axis view of the left ventricle of the mouse heart. The photoacoustic image is a parametric map of oxygen saturation in the myocardium.

3D rendered high-resolution ultrasound (greyscale) and photoacoustic (red) image of the mouse abdomen showing oxygen saturation in the kidney and spleen.

3D rendered high-resolution ultrasound (grey) and photoacoustic (red) image of the whole mouse abdomen showing highly absorbing gut contents overlaid with anatomy as visualized with ultrasound.

3D rendered high-resolution ultrasound (greyscale) and spectrally unmixed photoacoustic (red, blue and green) image of the mouse hindlbimb. The green color indicates ICG dye in the popliteal lymph node after a hindpaw injection, the red color indicated oxygenated hemoglobin and the blue color indicates deoxygenated hemoglobin.

3D rendering of a photoacoustic parametric map of oxygen saturation in the mouse ear. Red pixels indicate higher sO₂ values.

Oxy-hemo phototacoustics image showing oxygen saturation in two mid-gestational mouse implantation sites. Red indicates oxygenated hemoglobin; blue indicates de-oxygenated hemoglobin.
