Quantitative Evaluation of Temporal Regularizers in Compressed Sensing Dynamic Contrast Enhanced MRI of the Breast

Figure 1

An example sampling pattern for all dynamics (a) and a 2D sampling for one dynamic (b). The 2D mask on (b) is generated by repeating one column of the mask on (a). For each dynamic, the central lines are fully sampled and the periphery is randomly sampled. The total undersampling factor is around 4.5.
