Optical Frequency-Domain Imaging
Optical frequency-domain imaging or OFDI, is a parallel processing medical imaging method developed at the end of 2008, by Massachusetts General Hospital researchers. It uses a constantly rotating laser tip that continually modulates its wavelength, to pass through the body, and collect data on how each wavelength is reflected back.

As the demands for precise imaging in fields such as medicine, astronomy, and real-time machine vision in hostile environments continue to increase, so the demands placed on imaging equipment become ever more stringent. An imaging method based on Single Photon Avalanche Photodiodes (SPAD) offers the potential to ease this bottleneck greatly.
Technology Review's long, and in depth look at the rise of diffusion spectrum imaging, and how this new neural interface imaging technique is rapidly accelerating the study of both human and animal brains to an extent unparalleled by any previous imaging technique, even fMRI.
Diffusion spectrum imaging is a new technique at time of writing, which allows magnetic resonance brain imaging, at a much higher level of fidelity than fMRI permits.
