Fast
imaging techniques based on under-sampling are all approaching the problem
from the acquisition side. Less effort has been involved in exploring the
possibility of speeding up image acquisition from the excitation side.
Although parallel excitation is focused on the excitation side, it is
typically used to reduce the RF pulse duration rather than accelerate image
acquisition. In this work, a new technique is introduced to speed up image
acquisition from the excitation side. This technique is independent of other
techniques focused on the acquisition side and thus may be combined with them
to achieve a higher acceleration factor.
