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.
