In vivo 3D rendered coregistered high-resolution ultrasound (greyscale) and photoacoustic (red, white and blue) image of a mid-gestational fetus and its associated placenta. The photoacoustic signal represents a parametric map of oxygen saturation with red values representing higher sO2.
Images were acquired using the Vevo LAZR-X Imaging Platform.
