Fig. 5From: Optimal control theory for applications in Magnetic Resonance Imaging(Color online) Figure of merit surface Q(y m ,z m ) associated with the steady-state syntheses of Fig. 4. The solid, dashed and dot-dashed lines represent the boundaries between the different regions of the Bloch ball where the control law is not the same. The definition of these lines is given in Fig. 4 Back to article page
