Determination of optimized regularization parameters. The graphs illustrate the results for a Golden Angle simulation, using 8 projections and GRAPPA acceleration of 4. The combined map allows determining a pair of regularization parameters α,μ which fulfil a best compromise for all errors investigated. As the location of the valley within the combined map was very similar throughout all simulations, a joint pair of parameters was determined for all settings, thereby making the further usage of the reconstruction method more comfortable.
