  1. ncbi Modeling anisotropic light propagation in a realistic model of the human head
    Juha Heiskala
    BioMag Laboratory, Helsinki University Central Hospital, FIN 00029 HUS, Finland
    Appl Opt 44:2049-57. 2005
    ..An anisotropic diffusion equation that corresponds to our Monte Carlo model is derived, and a comparison between the Monte Carlo model and the diffusion equation solution with finite elements is given...
  2. ncbi Significance of tissue anisotropy in optical tomography of the infant brain
    Juha Heiskala
    BioMag Laboratory, Helsinki University Central Hospital, Helsinki, Finland
    Appl Opt 46:1633-40. 2007
    ..Anatomical and diffusion tensor magnetic resonance imaging of neonates are used for creating the anatomical models. We find that tissue anisotropy affects the measured signal and the pattern of sensitivity in optical measurements...

    J Heiskala
    BioMag Laboratory, HUSLAB, Helsinki University Central Hospital, PO Box 340, FI 00029 HUS, Finland
    Phys Med Biol 54:535-54. 2009
    ..Localization accuracy of small perturbations was found to be 2-3 mm with accurate a priori knowledge of the background optical properties, when a grid with high optode density (>1 optode cm(-2)) was used...
  4. ncbi Probabilistic atlas can improve reconstruction from optical imaging of the neonatal brain
    Juha Heiskala
    BioMag Laboratory, HUSLAB, Helsinki University Central Hospital, PO Box 340, FI 00029 HUS, Finland
    Opt Express 17:14977-92. 2009
    ..The results suggest that use of generic anatomical information can greatly improve the spatial accuracy and robustness of the reconstruction when noise is present in the data...
