title: Hybrid technique for dynamic imaging.
abstract: A number of data acquisition strategies have been introduced to speed up the image acquisition in dynamic settings. One such technique is the keyhole approach, which is based on reducing k-space coverage, and consequently the spatial resolution, of the dynamic information. Another is based on reducing the field of view of the dynamic information. These two techniques are complementary in that one reduces the field of view in k-space and the other does so in the spatial domain. A hybrid approach which combines the two is described in this study. In numerical simulations and experimental studies, this hybrid approach more accurately depicts the signal changes, outperforming the two techniques from which it is derived.
