Three-dimensional reconstruction in nuclear medicine emission imaging

Abstract

The study presents application of methods of ascertaining the three-dimensional distribution of isotope concentration or density in nuclear medicine, and differs from previous three-dimensional reconstruction efforts of astrophysics, electron microscopy, and X-ray radiology in that statistically poor measurements and photon attenuation are taken into account by the algorithm. The methods discussed are applicable to photon or heavy ion transmission radiography as well as emission imaging.
