An application of the Slepian‐Pollak‐Landau “time and band limited functions” is found in NMR imaging. The precise context is best described by the rotating‐frame dynamics of the Bloch equations, where an analogy is made to the problem of simultaneously concentrating a function in time and frequency. The appropriately modulated rf fields are found to yield excellent response characteristics when used in numerical simulations of the Bloch equations.© 1985 Academic Press,Inc.
