Radon变换和衰减Radon变换的分析研究
THE ANALYTIC STUDY ON THE RADON TRANSFORM AND THEATTENUATED RADON TRANSFORM
摘要
Abstract
The attenuated Radon transform arises in single photon emission computedtomography (SPECT). The Radon transform and attenuated Radon transform are reviewed,and a new method of proof of the Tretiak-Metz results is presented. For a general object theinverse attenuated Radon transform is derived by means of transform techniques but nonfilt ered-backprojection method.关键词
