Color Doppler Optical Coherence Tomography (CDOCT)
Images of in- vivo hamster skin. The top image was created using the magnitude of the detected signal. Structural information (various layers of the skin) are seen in this image. The surface of the skin (epidermis) is at the top of the image.

The bottom image was created by looking at the spectrum of the returned signal to identify Doppler shifts caused by moving blood. Three blood vessels are seen in this image.

After a series of CDOCT images are taken, a three dimensional reconstruction can be formed. Here, the blood vessels (red and blue) are seen, as are the interfaces of the skin (gray).
