Abstract:
A method for collecting optical imaging data for generating an image of a turbid medium with an enhancement of image data related to at least one longitudinal zone defined by spatial position between an optical source and an optical detector, the method comprising:arranging an optical source and an optical detector on opposite sides of a turbid medium; selecting a plurality of aperture configurations for said source and said detector in accordance with said zone selected, wherein said aperture configurations are selected from at least: a small aperture source and small aperture detector for enhancing image data related to a longitudinal zone proximal said source and said detector; a small aperture source and large aperture detector for enhancing image data related to a longitudinal zone proximal said source; and a large aperture source and small aperture detector for enhancing image data related to a longitudinal zone proximal said detector; scanning said source and said detector over said opposite sides using said plurality of aperture configurations to collect said image data; and combining said image data collected from said plurality of aperture configurations to generate said image of the turbid medium with said enhancement of image data related to said at least one longitudinal zone.
