A continuous, as opposed to sampled, mathematical description applicable to 3-D image reconstruction from 2-D projections is applied to three examples. These examples are computer tomography, tomosynthesis, and coded-source tomosynthesis. The effects of various projection filtering procedures on reconstructed image quality are discussed for each example.
