Popis: Two different tomographic scanning instruments have been interfaced to a digital computer. Digital backprojection is used to produce multiple tomographic images of radioactive distributions. Backprojection results in blur artifacts due to off-plane contributions which obscures the detail in images. The method of Chang, Macdonald, and Perez-Mendez has been applied to phantom data from both instruments, resulting in substantial blur removal and improved signal-to-noise ratios. Clinical images derived from digital back-projection of data from the Searle PHO/CON-192 Multiplane Imager are presented and compared with images from the Searle Microdot imager.
