Direct estimation of kinetic parameters from the sinogram with an unknown blood function

Abstract

Kinetic parameter estimation using PET is an important tool for quantification of the acquired image. Often a known blood function is assumed and the parameters are estimated using reconstructed PET images. However, obtaining blood function using arterial sampling or estimating it from a region in the PET image has certain disadvantages. In this paper, we… (More)
