ABSTRACT:
A Magnetic Resonance (MR) data acquisition system using driven equilibrium in a spin echo scan sequence wherein the dephased spins in the transverse plane are accurately refocused prior to being driven to the Z axis and the encoding gradient pulses are distributed and adjusted to keep the encoding gradient pulses from affecting the refocused magnetization.
