Алгоритм локализации областей патологических нарушений в оптической структуре биологических тканей посредством импульсной диффузионной оптической томографии

Abstract

Описан алгоритм локализации областей патологических нарушений в оптической структуре биологических тканей предназначенный для импульсной диффузионной оптической томографии. Отличительными особенностями алгоритма являются формирование начального приближения к пространственным распределениям оптических характеристик по индексу неоднородности (HI), а также предположение о том, что все оптические неоднородности в исследуемой биологической ткани являются сферическими и однородными по значениям показателей поглощения и рассеяния внутри каждой из них. Предложенный алгоритм может быть использован при диагностике структур головного мозга, в травматологии, а также при маммографических исследованиях.

Biological tissue optical structure disturbance localization algorithm for time-resolved diffuse optical tomography is described. The key features of the presented algorithm are: the initial approximation for the spatial distribution of the optical characteristics based on the Homogeneity Index (HI) and the assumption that all the absorbing and scattering inhomogeneities in an investigated object are spherical and have the same absorption and scattering coefficients. The described algorithm can be used in the brain structures diagnosis, in traumatology and mammography.
