一种新的绝热脉冲，它可以诱导均匀和任意的翻转角，尽管发射线圈磁场（B1）的不均匀性的存在，使用一个单一的表面线圈的脉冲传输和信号检测的三维快速成像。计算机计算和幻影，大鼠，和人体表面线圈成像实验表明，这种绝热脉冲的效用T1加权成像与发射线圈，产生一个高度不均匀的B1场分布。
A new adiabatic pulse, which can induce uniform and arbitrary flip angles despite the presnce of transmitter coil magnetic field (B1) inhomogeneities, is employed for 3-D fast imaging using a single surface coil for pulse transmission and signal detection. Computer calculations and phantom, rat, and human surface coil imaging experiments demonstrate the utility of this adiabatic pulse for T1-weighted imaging with a transmitter coil which generates a highly inhomogeneous B1 field profile.
