Abstract:
1. A method comprising: providing a probe comprising a plurality of first structures, a plurality of second structures, and a plurality of third structures, wherein the first structures comprise sources, and the second and third structures comprise detectors, the first structures are arranged in a first line, the second structures are arranged in a second line, and the third structures are arranged in a third line, the first, second, and third lines are parallel to each other, and the second line is between the first and the third lines; using the first and second structures of the probe, calculating a first oxygen saturation measurement for a first tissue at a first depth below a tissue surface, wherein the first tissue comprises a three-dimensional region and at the first depth, this region extends in directions parallel and transverse to the second line; using the first and third structures of the probe, calculating a second oxygen saturation measurement for a second tissue at a second depth below the tissue surface, wherein the second depth is beneath the first depth, and the second tissue comprises a three-dimensional region and at the second depth, this region extends in directions parallel and transverse to the third line; displaying a first value indicative of the first oxygen saturation measurement at a first position on a screen; and displaying a second value indicative of the second oxygen saturation measurement at a second position on the screen, wherein the probe comprises a first light shading film, associated with the second structures, allowing a first spectrum of light to pass through to the second structures, and a second light shading film, associated with the third structures, allowing a second spectrum of light to pass through to the third structures, wherein the first spectrum is different from the second spectrum.
