Abstract Background The inverse problem of fluorescent molecular tomography (FMT) often involves complex large-scale matrix operations. which may lead to unacceptable computational errors and complexity. In this research. a tree structured Schur complement decomposition strategy is proposed to accelerate the reconstruction process and reduce the computational complexity. https://www.ngetikin.com/deal-time-Orange-Zinger-Tomato-Container-Cherry-Tomatoes-Lycopersicon-Esculentum-5-Seeds-mega-super/
