In multi-band imaging technique, we propose a new
multi-band imaging technique by using the RF pulse
modulation with random phase to make uncorrelated
aliasing pattern. To make the controlled aliasing for
multi-band imaging, we make the RF pulse modulated with
random phases. The phases are increasing by Golden
Ratio, and the sets of phases are segmented by Fibonacci
numbers and randomly reordered. Randomly distributed
aliasing pattern can be reduced by using CS
reconstruction. In this paper, experimental results with
acceleration factor 6 are shown.
