A tomographic apparatus includes a radiation source (12) having a plurality of focal spots (F<SUB>a</SUB>, F<SUB>b</SUB>, F<SUB>c</SUB>, F<SUB>d</SUB>) and a detector (20) which generates output signals indicative of radiation received along a plurality of rays. A height rebinner (34) performs a height rebinning of the acquired rays to generate height interpolated readings. A transverse rebinner (36) performs a two-dimensional transverse interpolation of the height interpolated rays in a canonical space to generate a plurality of transversely interpolated readings (302). The transversely interpolated readings (302) are reconstructed to generate a human readable image. |
