Claim One:
1. A non-transitory computer readable medium embodying a program of instructions executable by machine to perform steps for facilitating iterative data reconstruction, the steps comprising: (i) receiving a time-varying two-dimensional (2D) image dataset of one or more structures of a biological object of a patient; (ii) forward projecting temporal volumes in a current estimated time-varying three-dimensional (3D) dataset to obtain 2D attenuation coefficients, and determining an error between the 2D attenuation coefficients corresponding to the current estimated time-varying 3D dataset and corresponding projection data from the received time-varying 2D image dataset; and (iii) back projecting the error across the temporal volumes in the current estimated time-varying 3D dataset to adjust the current estimated time-varying 3D dataset.
