High-resolution ultrasound (greyscale) and photoacoustic (red, blue and green) image of the mouse hindlimb showing Evan's Blue (blue) and ICG (green) dye in the lymphatic vessels and the popliteal lymph node.

3D rendered spectrally unmixed photoacoustic image of a stem-cell injected, ischemic (right) and control (left) mouse hindlimb. Oxyhemoglobin (red), deoxyhemoglobin (blue) and dye-labelled stem cells (green) are shown.

Screenshot of the Vevo LAB software displaying several different views of the CD-1 mouse brain atlas which comes with the Vevo BRAIN stereotactic frame.

3D rendered surface view of the mouse brain segmented by anatomical region based on ex vivo high frequency ultrasound images.

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.

Plot of oxygen saturation (sO₂) over time in the left (pink) and right (orange) cortical and subcortical hemisphere ROIs  while restoring breathed oxygen to 100% from 7.5% post ischemia/hypoxia for stroke induction.  Ultrasound (top) and photoacoustic (bottom) coronal images in the right panel show a frame of mouse brain post ischemia/hypoxia. The red, white and blue color represents a parametric map of oxygen saturation.  The right hemisphere does not fully recover sO₂ levels post-reperfusion/normoxia that are shown in the left hemisphere, indicating a cerebral infarct, especially in cortical and subcortical areas.

3D rendered power Doppler image of the mouse hindlimb showing blood flow. Application of a tourniquet made of tubing was used to restrict blood flow into the distal part of the limb, then relieved to allow reperfusion.

3D rendered photoacoustic image of the mouse hindlimb showing a parametric map of oxygen saturation with red denoting higher sO₂ values.  Application of a tourniquet made of tubing was used to restrict blood flow into the distal part of the limb, then relieved to allow reperfusion. Higher sO₂ is seen in the distal part of the limb post-reperfusion.

3D rendered photoacoustic image of the mouse hindlimb showing a parametric map of oxygen saturation with red denoting higher sO₂ values.  Application of a tourniquet made of tubing was used to restrict blood flow into the distal part of the limb. Much lower sO₂ is seen in the distal part of the limb during this acute ischemia.

3D rendered high-resolution ultrasound image of the mouse hindlimb showing a depression in the skin from a tourniquet made of tubing being used to restrict blood flow into the distal part of the limb.

In vivo co-registered high-resolution ultrasound (greyscale) and photoacoustic (red, white and blue) image of an E14 embryo and its associated placenta (on left of each image). The photoacoustic signal represents a parametric map of oxygen saturation with red values representing higher sO₂.  The image was acquired while the mother was breathing medical air (20% O₂). Oxygen saturation can be distinguished within differing placental and embryonic anatomy.

In vivo 3D rendered co-registered high-resolution ultrasound (greyscale) and photoacoustic (red) image of an E14 embryo and its associated placenta (on left). The photoacoustic signal was acquired at 750nm and represents signal from mostly deoxygenated hemoglobin.
