Abstract:
An optical system for in vivo, non-invasive imaging of biological tissue comprising:an optical module including an array of input and detection ports located in a selected geometrical pattern to provide a multiplicity of arrayed source-detector pairs constructed and arranged to be engaged directly with a subject; a spectrophotometer including a light source constructed to introduce electromagnetic radiation of a visible or infra-red wavelength into the examined tissue successively at said input ports, said wavelength being sensitive to a constituent of the imaged tissue; a light detector constructed to detect radiation of said wavelength that has migrated in the tissue from respective input ports to associated detection ports; and a processor receiving signals of said detected radiation from said detector, and constructed and arranged to create a defined spatial image of the tissue by effectively producing from signals from the multiplicity of arrayed source-detector pairs, a succession of data sets representing, from a selected view, a succession of spatial images of the tissue, and an image data set related to differences between data of said successive data sets.
