摘要：
A modified spiral imaging technique is presented, in which the conventional sinusoidal gradient waveforms are replaced by trapezoidal ones. In addition to allowing a reduced data acquisition time, the new waveforms circumvent specific hardware restrictions on the minimum scan repetition time. (C) 1997 Academic Press.
