Multi-wavelength photoacoustic imaging of a mouse liver. Lipid in yellow, oxyhemoglobin in red, and deoxyhemoglobin in blue. This was acquired using a UHF29x transducer on the Vevo F2xc imaging platform.

Oxy-Hemo view of a mouse brain. This was acquired using a UHF29x transducer on the Vevo F2xc imaging platform.

Unmixing from a PA Spectro scan showing lipid (yellow) in the skin layer, and oxy/deoxyhemoglobin (red/blue) in the tumor and surrounding tissue. Collagen (green) was included in the unmixing, but no noticeable signal above background. This was acquired using a UHF57x transducer on the Vevo F2xc imaging platform. 

PA Oxyhemo scan of a mouse tumor. This was acquired using a UHF57x transducer on the Vevo F2xc imaging platform.

PA signal at 850 nm (Oxyhemo) corresponding to the vasculature of a subcutaneous prostate tumor. This was acquired using a UHF57x transducer on the Vevo F2xc imaging platform.

Unmixing from a Spectro scan of the Subcutaneous prostate tumor and surrounding region. This was acquired using a UHF57x transducer on the Vevo F2xc imaging platform.

Colormap – red/blue = oxy/deoxyhemo; yellow = lipid, green = collagen (theoretical).

PA mode scans showing an OxyHemo sO₂ map of a subcutaneous prostate tumor. This image was acquired using a UHF57x transducer on the Vevo F2xc imaging platform.

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.
