In a.dyna.ic CT, the a.quired projections a.e corrupted due to strong dyna.ic na.ure of the object, for exa.ple: lungs, hea.t etc. In this pa.er, we present fa.-bea. reconstruction a.gorithm without position-dependent ba.kprojection weight which compensa.es for the time-dependent tra.sla.iona., uniform sca.ing a.d rota.iona. deforma.ions occurring in the object of interest during the da.a.a.quisition process. We sha.l a.so compa.e the computa.iona. cost of the proposed reconstruction a.gorithm with the existing one which ha. position-dependent weight. To a.complish the objective listed a.ove, we first formula.e a.missibility conditions on deforma.ions tha. is required to exa.tly reconstruct the object from a.quired sequentia. deformed projections a.d then derive the reconstruction a.gorithm to compensa.e the a.ove listed deforma.ions sa.isfying the a.missibility conditions. For this, 2-D time-dependent deforma.ion model is incorpora.ed in the fa.-bea. FBP reconstruction a.gorithm with no ba.kprojection weight, a.suming the motion pa.a.eters being known. Fina.ly the proposed reconstruction a.gorithm is eva.ua.ed with the motion corrupted projection da.a.simula.ed on the computer.
