WebThe defined field-of view ( FOV) and pixel width ( Δw) determine the number of digitized samples in k -space that must be obtained to reconstruct an image with the desired resolution. As shown in the diagrams below, FOV is inversely proportional to the spacing between samples in k -space. Specifically, Δk = 1/ FOV.
