Experimental definition of the 3 regions in the image used to define both the spatial-spectral support constraint, P, and the generalized support constraint, M. The cardiac region is white. The respiratory region is gray, and the empty region is black. The spatial regions are found by first thresholding a time averaged image and then manually selecting the cardiac region.
