600×350 pixel region-of-interest in reconstructed images corresponding to a slice of constant z. The image reconstructed from 1440 tomographic views by use of the FBP algorithm is contained in subfigure (a). Images reconstructed from 90 tomographic views by use of the IHT-POCS, and IHT-POCS-TV algorithms are displayed in subfigures (b) and (c).
