Patent ID: 8655433

Claim:
A multispectral or hyperspectral medical imaging system comprising: a plurality of LED lights, each respective LED light in the plurality of LED lights configured to emit radiation at a particular spectral band in a plurality of spectral bands used by a diagnostic protocol module; a first stage optic configured to receive radiation projected, from one or more respective LED lights in the plurality of LED lights, off of an in vivo tissue located at a region of interest on a subject; an imaging sensor for recording an image of the radiation projected off of the in vivo tissue; a diagnostic protocol module adapted to detect a particular characteristic of the in-vivo tissue; a diagnostic processor configured to: switch one or more respective LED light in the plurality of LED lights off and on based on the diagnostic protocol module, instruct the imaging sensor to record a plurality of images of the region of interest based on the diagnostic protocol module, each respective image in the plurality of images corresponding to radiation emitted at a particular spectral band by one or more respective LED light in the plurality of LED lights, co-register corresponding pixels in each image in the plurality of images; derive a coefficient for oxyhemoglobin and a coefficient for deoxyhemoglobin from each set of co-registered pixels in the plurality of images; generate, based on the plurality of images, a two-dimensional index characterizing the particular characteristic of the in vivo tissue, wherein the two-dimensional index includes a first scale to represent a concentration of oxyhemoglobin in the in vivo tissue, and a second scale to indicate a concentration of deoxyhemoglobin in the in vivo tissue; display the coefficient for oxyhemoglobin and the coefficient for deoxyhemoglobin from at least one set of co-registered pixels in the plurality of images independently with the two-dimensional index on a video display, thereby conveying spatial information about oxyhemoglobin concentration and deoxyhemoglobin concentration in the tissue.
