摘要
Methods, systems, and related computer program products for non-invasive monitoring of a biological volume, such as a human brain, are described. In one preferred embodiment, each of a plurality of optical sources emits optical radiation into the biological volume each of a plurality of optical detectors detects optical radiation impinging thereupon from the biological volume. The optical measurements are processed to compute a requisite property value associated with each source-detector pair. For each source-detector pair, a volumetric basis region corresponding thereto is weighted by the requisite property value, the volumetric basis region being predetermined and representative of an estimated subvolume of the biological volume encountered by optical radiation emitted from that source and propagating to that detector. The weighted volumetric basis regions are accumulated into a volumetric cumulative array, and a display output is generated based at least in part on the volumetric cumulative array.
