摘要：An optical examination technique employs an optical system for in vivo non-invasive examination of breast tissue of a subject. The optical system includes an opticalmodule, a controller and a processor. The optical module includes an array of optical
input ports and optical detection ports located in a selected geometrical pattern toprovide a multiplicity of photon migration paths inside the biological tissue. Each opticalinput port is constructed to introduce into the examined tissue visible or infrared lightemitted from a light source. Each optical detection port is constructed to provide lightfrom the tissue to a light detector. The controller is constructed and arranged to activateone or several light sources and light detectors so that the light detector detects lightthat has migrated over at least one of the photon migration paths. The processorreceives signals corresponding to the detected light and forms at least two data sets, afirst of said data sets representing blood volume in the examined tissue region and asecond of said data sets representing blood oxygenation of the examined tissue. Theprocessor is arranged to correlate the first and second data sets to detect abnormaltissue in the examined tissue.
