Abstract

In theory, multidimensional pulses can be designed to be selective in any number of dimensions. In practice, available gradient power has enforced a limit to two dimensions. We show here that three‐dimensional π pulses are feasible on commercial imaging machines provided that the range of offresonance frequencies are limited.

## Abstract The echo‐planar __k__‐space trajectory can be used as the basis for any two‐dimensional selective pulse. The main application is spectral‐spatial pulses, which must be based on the echoplanar trajectory. In this paper we show how echo‐planar spinecho (EPSE) pulses may be designed.

## Abstract Three‐dimensional (3D) magnetic resonance imaging allows thin‐section acquisition and therefore more accurate multiplanar reconstruction than conventional two‐dimensional spin‐echo imaging. Unfortunately, addition of a third acquisition plane extends imaging time greatly. With gradient‐
