The image shows a 3D volume of a human forearm, combining metabolic and structural information. Two different optical imaging modalities have been used, namely diffuse multi-spectral imaging and Optical Coherence Tomography (OCT). Multi-spectral imaging enabled us to extract blood volume concentrations over the entire image area (4cm x 4cm); OCT was used to obtain the 3D structure of the epidermis and dermis. Image segmentation on the OCT image was performed to extract the surface of the arm, used for mapping blood concentration. Hence the upper part of the image is the skin surface, colorcoded with blood concentrations in the underlying skin. Veins can be clearly identified due to increase in blood. The lower part of the image shows the structure of the skin obtained by OCT, where the epidermal and dermal structures can be well separated from each other.

Image of a Directionally encoded color (DEC) map of the human brain obtained using diffusion tensor MRI showing the white matter pathways. This tool is useful in visualizing the fiber directions within the brain enabling the investigation of the structural anatomy.

3-dimensional view of NMR spectrum attenuation by diffusion gradients. Solution of N-acetyl-L-aspartic acid (NAA) in deuterium oxide (D2O). Water residue peak (4.8 ppm) is attenuating much more than NAA peak (2.06 ppm) with increasing diffusion gradient field intensity.
