Abstract
The subject invention pertains to a method and apparatus utilizing one or more spiral coils, such as spiral birdcage coils, spiral saddle coils, Helmholtz coil pairs, and other spiral volume and spiral surface coils. The spiral coils of the subject array can be substantially isolated from each other while covering nearly the same volume or surface. For cylindrical geometrics, isolation can be enhanced by having the rotation, or change in direction from one end of the coil to the other, be 2n.pi., where n is an integer.
