摘要
An image reconstruction method for diffuse optical tomography is implemented using a diffuse optical tomography system, and includes the steps of: a) activating one of optical detecting units of the diffuse optical tomography system to emit a near-infrared ray to illuminate a target for outputting a received light signal corresponding to one of a plurality of sub-frames of the tomographic image of the target; b) obtaining a light intensity matrix based upon the received light signal; c) obtaining an absorption coefficient matrix corresponding to the one of the sub-frames based upon a product of the light intensity matrix and an inverse matrix of a weight matrix; d) repeating steps a) to c) with activating another one of the optical detecting units until the absorption coefficient matrices corresponding respectively to the sub-frames are obtained; and e) reconstructing the tomographic image of the target based upon the absorption coefficient matrices.
