We derived and successfully implemented on GPU a tomographic reconstruction method whichrelaxes the requirement that the sample does not change during the acquisition of one tomographic projection.In the presented method, time-resolved data is decomposed in the temporal domain by projecting to a lowerdimensional subspace and deploying additional Total Variation regularization for spatial and temporal variables.
