3D rendered photoacoustic image of the mouse hindlimb showing a parametric map of oxygen saturation with red denoting higher sO 2 values.  Application of a tourniquet made of tubing was used to restrict blood flow into the distal part of the limb, then …

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 .   … … Mouse hindlimb …

Ultrasound (left) and photoacoustic (right) coronal images of a 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 sO 2 levels post- reperfusion …

Plot of oxygen saturation (sO 2 ) 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 …
