Problem 10.5 Assume that the slice select gradient amplitudes are changed from those shown in Fig. 10.11 to be Gor=-Goy2Go What are the angles and of the resulting slice? Draw the excited plane (use Fig. 10.10 as a guide). rf G Gy G GO Goy Fig. 10.11: Sequence diagram showing gradient waveforms (with rephasing lobes) required to excite an arbitrary slice. The ratios of the different components are fixed during the time the three gradients are applied.
