Exploring the physical limits of saturation contrast in Magnetic Resonance Imagign
M. Lapert, Y. Zhang, M. Janich +2
Magnetic Resonance Imaging has become nowadays an indispensable tool with applications ranging from medicine to material science. However, so far the physical limits of the maximum…
Saturation of a spin 1/2 particle by generalized Local control
F. Mintert, M. Lapert, Y. Zhang +2
We show how to apply a generalization of Local control design to the problem of saturation of a spin 1/2 particle by magnetic fields in Nuclear Magnetic Resonance. The generalizati…
Simultaneous time-optimal control of the inversion of two spin 1/2 particles
E. Assemat, M. Lapert, Y. Zhang +3
We analyze the simultaneous time-optimal control of two-spin systems. The two non coupled spins which differ in the value of their chemical offsets are controlled by the same magne…
Singular extremals for the time-optimal control of dissipative spin 1/2 particles
M. Lapert, Y. Zhang, M. Braun +2
We consider the time-optimal control by magnetic fields of a spin 1/2 particle in a dissipative environment. This system is used as an illustrative example to show the role of sing…
