As the number and complexity of partially sampled dynamic imaging methods continues to increase, a reliable method to evaluate performance would be important. In the present work, an analytical formulation to evaluate the reconstruction efficiency of given fast imaging strategies was proposed. Assessments in terms of MTF, signal to artifact ratio and noise enhancement are visualized graphically, for all combinations of temporal and spatial frequencies. Three fast imaging strategies, kt-SENSE, UNFOLD-SENSE and a combination of the two (hybrid SENSE) were tested to illustrate their respective abilities, using in-vivo datasets.
