The paper presents an original approach to time‐domain reflectance fluorescence molecular tomography (FMT) of small animals. It is based on the use of early arriving photons and state‐of‐the‐art compressed‐sensing‐like reconstruction algorithms and aims to improve the spatial resolution of fluorescent images. We deduce the fundamental equation that models the imaging operator and derive analytical...
The paper considers a new iterative algorithm for tomographic image reconstruction when a very limited number of projections are registered. The algorithm uses a priori information on the discrete values of the object function to be reconstructed and is based on the known multiplicative algebraic reconstruction technique (MART). The new algorithm we called MART-AP organizes a cycle of “external” iterations...
The paper considers a layer-to-layer 3D reconstruction method for diffuse optical mammotomography which uses conic geometry for time-domain measurements. The method is based on an approximate 2D reconstruction of transverse layers of a conic scattering object by inverting an integral equation with integration along a photon average trajectory. The equation is inverted using a backprojection algorithm...
