Simultaneous excitation
and acquisition is a promising approach to acquire MR images using very low
transmission power. This concept is also well-suited for imaging tissues and
materials with ultrashort T2* relaxation times since no echo time exists. In
this work, a cSWIFT hardware setup, pulse sequence, and reconstruction were
designed for and implemented on a whole-body 7T system. Spectroscopy and
imaging of phantoms and in vivo imaging
of the human forearm were successfully performed. Feasibility of cSWIFT with
the implemented setup was demonstrated.
