Two-dimensional selective adiabatic pulses.

Magnetic resonance in medicine

Conolly S, Pauly J, Nishimura D, Macovski A.
PMID: 1569869
Magn Reson Med. 1992 Apr;24(2):302-13. doi: 10.1002/mrm.1910240211.

Using the technique of separable k-space excitation, we have designed a two-dimensional selective adiabatic pulse that inverts magnetization from a square region in the xy plane with insensitivity to RF variations. We also have designed a two-dimensional adiabatic pulse...

A new approach to split resonator design.

Magnetic resonance in medicine

Harpen MD.
PMID: 1569874
Magn Reson Med. 1992 Apr;24(2):364-9. doi: 10.1002/mrm.1910240217.

Using a novel application of the method of images we show how a plane array of resonant elements can be substituted for the conducting plane in a semicylindrical or split resonator. In an experimental low-pass split resonator-plane array system...
