PET Image Reconstruction with Multiple Kernels and Multiple Kernel Space Regularizers

no code implementations4 Mar 2021 Shiyao Guo, Yuxia Sheng, Shenpeng Li, Li Chai, Jingxin Zhang

To reduce the reconstruction error and the sensitivity to iteration number, we present a general class of multi-kernel matrices and two regularizers consisting of kernel image dictionary and kernel image Laplacian quatradic, and use them to derive the single-kernel regularized EM and multi-kernel regularized EM algorithms for PET image reconstruction.
