Optical imaging

Welcome to Diffuse Optical Imaging
This is part of the Medical imaging wiki, and is based on a recent review paper, formatted in the style of a wikia article. Please help to make it into a comprehensive, up-to-date review of diffuse optical imaging by editing it. Feel free to add new references, new links, new text and new images. In fact, you can make any changes you like, but please consider creating an account first so we know who you are.

Why Wikia?

 * Wikia are like Wikipedia but more general. Wikipedia has some restrictions. It does not allow original research and there's a limit to the amount of information it can host on one subject. Wikia, however, don't have these restrictions and so are more appropriate for a resource such as this.

Abstract
We review the current state of the art of diffuse optical imaging, which is an emerging technique for functional imaging of biological tissue. It involves generating images using measurements of visible or near-infrared light scattered across large (> several cm) thicknesses of tissue. We discuss recent advances in experimental methods and instrumentation, and examine new theoretical techniques applied to modelling and image reconstruction. We review recent work on in vivo applications including imaging the breast and brain, and examine future challenges.
