A technique is set forth that is designed to reduce RF induced power in high
field
MR imaging that includes application of an initial contrast preserving phase of
RF pulses. These initial RF pulses are designed to have a constant, relatively
high flip angle over the initial contrast preserving phase. Following an effective
TE, a ramp down phase is applied that has a limited number of RF pulses with a
flip angle that is less than the flip angle of those in the initial contrast preserving
phase. Further, the RF pulses in the ramp down phase have a flip angle that is
decreased over the ramp down phase. This technique provides improved resolution
and steady contrast and SNR, while significantly reducing induced RF power.
