Abstract
A new method of 3D spatial selection using pulsed quadratic field gradients is presented. Like previous pulsed quadratic gradient methods the new method requires only two RF pulses to achieve selection in three dimensions. Unlike previous methods, however, precise alignment of linear and quadratic gradient coils is not required. This characteristic allows the method to be used with small or surface quadratic gradient coils. The method is demonstrated on phantoms and rats.

## Abstract A new spatial localization method using an additional set of highβorder magnetic field gradients is described. The method uses a nonlinear part of highβorder magnetic field gradient patterns which allows us to select a volume in conjunction with the selective radiofrequency (RF) pulse.
