Radial MR imaging is presented in which the linear gradient fields are generated by a matrix of individual, generic coils. The ability of this multi-coil concept for magnetic field modeling to flexibly trade accuracy for efficiency is applied to increase the available gradient strength and imaging bandwidth multi-fold. MC imaging bears the potential of providing an inexpensive alternative for specialized imaging applications for which maximum gradient strength and performance are not required.
