Low-power NMR volume selection by slicing z magnetization.
A novel method for reducing the rf power requirements of selective pulses employed for z magnetization slice inversion in localized NMR spectroscopy is presented. Following slice preparation by the use of frequency-incremented sinc pulses, the slice gradient is reduced, which narrows the frequency width of the slice. This allows the use of relatively low-power selective inversion pulses, an important consideration for in vivo applications.
