  • Abstract: Incorporation of resolution modelling (RM) into iterative reconstruction produces Gibbs ringing artefacts which adversely affect clinically used metrics such as SUV${}_{\mbox{max}}$. We propose the use of a null space network as a regulariser to compensate for these artefacts without introducing bias.
