摘要：

Dynamic Positron Emission Tomography allows monitoring physiological processes within the body that can be described by kinetic parameters. However, recovery of these parameters often requires the solution of complex and nonlinear operator equations. Advanced operator splitting techniques allow incorporating a-priori knowledge, e.g. sparsity of minimizers with respect to all exponential basis, into the reconstruction process.
