ABSTRACT:
Methods and systems are described that examine a subject positioned between input and detection ports of a spectroscopic system applied to the subject. At least one least source is provided that introduces at one or multiple input ports electromagnetic non-ionizing radiation into the subject of a visible or infrared wavelength selected to be scattered and absorbed while migrating in the tissue. A detection port is optically connected to a detector; the detector being connected to a detector circuit. For each input port first and second radiation intensities are selected to be introduced to the tissue; the selected radiation intensities defining a null plane in the tissue. The detection port is positioned relative to a selected detection location of the examined tissue corresponding to the null plane. Radiation of the first intensity is introduced into the subject, at the first input port and the first radiation that has migrated in the examined tissue is detected. The detector circuit stores a first detector signal corresponding to the first detected radiation. Radiation of the second intensity is introduced into the subject, at the second input port and the second radiation that has migrated in the examined tissue is detected. The detector circuit stores a second detector signal corresponding to the second detected radiation. The first detector signal is subtracted from the second detector signal to obtain processed data.
