摘　　要：A two-dimensional （2D） shape-based approach of image reconstruction using a boundary element method is developed for diffuse optical tomography （DOT）. The experimental validation uses a four-channel time- correlated single photon counting （TCSPC） system for detection and an intensity data-type for image reconstruction. The optical and geometric parameters are simultaneously recovered using a difference imaging scheme. Results demonstrate that the proposed DOT modality is a promising methodology of in vivo reconstruction of the optical structures of tissues.A two-dimensional （2D） shape-based approach of image reconstruction using a boundary element method is developed for diffuse optical tomography （DOT）.
