With the implement of PET-MRI, simultaneously MRI and
PET image acquisition becomes real. Researchers have
been wondering how to use high resolution MRI image to
improve the PET image quality. In this work, we proposed
a iterative residual based deconvolution method using
MRI information for PET partial volume effect correction
which is one of the major causes for PET low spatial
resolution. Proposed method perform well in lesion
contrast enhancement without introducing additional
noise to image. Both phantom simulation and in-vivo
result is shown in this work.
