Power Doppler imaging showing vascularization in the various regions of the placenta.

Co-registered high-resolution ultrasound (greyscale) and photoacoustic (red, white and blue) image of a mid-gestation embryo (left) and its associated placenta. The photoacoustic signal depicts oxygen saturation, with red representing regions of higher sO₂.

Mouse ovary acquired using ultra high frequency ultrasound (Vevo 3100) against an image of the same mouse ovary using a conventional ultrasound system. 

Spina Bifida is a neural tube defect that results in incomplete closing of the spinal cord. Spina bifida is associated with abnormalities in the cerebellum and cisterna magna during fetal development.

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, white and blue) image of an E14 embryo and its associated placenta (on left).

In vivo 3D rendered co-registered high-resolution ultrasound (greyscale) and photoacoustic (red, white and blue) image of an E14 embryo and its associated placenta (on left). 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 100% oxygen.

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.
