“…Note that pre-alignment of variable flip-angle data is challenging, as intensities vary with different flip-angles. To overcome this issue, a model-based registration method similar to the ones described in Hallack et al 9 and Heck et al 14 was used for registration. Note that our modification has some mild smoothness assumptions on the parameter maps for stability.…”

“…13 In the special case of abdominal MRI of, e.g., kidney or prostate, an additional requirement is measurement speed, as motion by breathing or heart-beat complicates the acquisition process. 9,14 A T 1 reconstruction method which fulfils these requirements is the variable flip angle method. 3,4,[10][11][12] The variable flip angle method has been shown to yield both fast and accurate results and is based on so-called spoiled gradient echo (SPGR) sequences, which are common in clinical MRI.…”

“…Therefore, an appropriate measure of dependency such as Schatten-q-norms [24] are excellent regularizers in color image denoising. This idea can be generalized to more than three channels and is therefore useful in applications such as parameter estimation in DCE-MRI [8] or the registration of multiple images as they appear for example in serial sectioning or time series [11]. , ∇u3] ∈ R 2,3 of three color channels; illustration adapted from [14].…”
