摘要：An optical examination technique employs an optical system (15, 45, 100, 150,200, 260 or 300) for in vivo non-invasive examination of breast tissue of a subject. Theoptical system includes an optical module (12 or 14), a controller and a processor. Theoptical module includes an array of optical input ports and optical detection portslocated in a selected geometrical pattern to provide a multiplicity of photon migrationpaths inside the biological tissue. Each optical input port is constructed to introduce intothe examined tissue visible or infrared light emitted from a light source. Each opticaldetection port is constructed to provide light from the tissue to a light detector. Thecontroller is constructed and arranged to activate one or several light sources and lightdetectors so that the light detector detects light that has migrated over at least one ofthe photon migration paths. The processor receives signals corresponding to thedetected light and forms at least two data sets, a first of said data sets representingblood volume in the examined tissue region and a second of said data sets representingblood oxygenation of the examined tissue. The processor is arranged to correlate thefirst and second data sets to detect abnormal tissue in the examined tissue.
