Abstract
We show how high-resolution parallel-projection images can be obtained with a synthetic collimator, a device that consists of a multiple-pinhole aperture with detector arrays in several locations behind it. Simulation studies indicate that this system is superior to a parallel-hole collimator system for parallel-projection imaging. We also show how three-dimensional reconstructions can be created with the synthetic collimator and present evidence from simulations that lesion detection will be better in these reconstructions than in either of the parallel-projection imaging systems.
