Abstract

Crosstalk between oxy- and deoxy-haemoglobin observed in near-infrared topography is investigated. The topographic images of changes in oxy- and deoxy-haemoglobin are obtained from the changes in intensity detected with source-detector pairs. The crosstalk depends on the relative position of the focal absorption change to source-detector pairs. Appropriate selection of wavelength pair is effective to reduce the crosstalk in the topographic image.
