  • Title: Image correction scheme applied to functional diffuse optical tomography scattering images.
    Author: Graber HL, Xu Y, Barbour RL.
    Journal: Appl Opt; 2007 Apr 01; 46(10):1705-16. PubMed ID: 17356613.
    Abstract:
    We have extended our investigation on the use of a linear algorithm for enhancing the accuracy of diffuse optical tomography (DOT) images, to include spatial maps of the diffusion coefficient. The results show that the corrected images are markedly improved in terms of estimated size, spatial resolution, two-object resolving power, and quantitative accuracy. These image-enhancing effects are significant at expected levels of diffusion-coefficient contrast in tissue and noise levels typical of experimental DOT data. Overall, the types and magnitudes of image-enhancing effects obtained here are qualitatively similar to those seen in previous studies on mu(a) perturbations. The implications for practical implementations of DOT time-series imaging are discussed.
