Paper Abstract

The ideal observer signal-to-noise ratio is used to derive the multiplex penalty associated with line-integral-projection imaging modalities. This penalty explains the high exposures required in computed tomography. The same multiplexing phenomenon applies to diffraction tomography--the radiofrequency inverse problem, or holography of semi-transparent objects. For the planar case the multiplex penalty enters to the second power, i.e., it is an areal penalty. We show that the approach of compound B-scanning--which avoids multiplexing by conventional ranging--remains quite competitive in the face of the more general tomographic approach.
