  • Separation of geometric system response matrix for three-dimensional image reconstruction
    Patent number: 7557351
    Abstract: An image-reconstruction method in which interactions with particular crystal pairs are detected and a trans-axial component of a geometric system response matrix is retrieved from a storage medium. This component provides an estimate of an axial component of the geometric system response matrix. At least in part on the basis of the axial component and the trans-axial component, an annihilation site distribution of annihilations most likely to have resulted in the interaction with the particular crystal pair is estimated.
