Given a statistical model that specifies the dependence of the measured data on the state of the dynamical system, the design of maximally informative inputs to the system can be formulated as a mathematical optimization problem using the Fisher information as an objective function.

In particular, we use optimal experiment design algorithms to compute optimized flip angle sequences for MRF and hyperpolarized carbon-13 acquisitions as well as optimized tracer injection inputs for estimating metabolic rate parameters in hyperpolarized carbon-13 acquisitions. Unknown parameters in models of dynamical systems can be learned reliably only when the system is excited such that the measured output data is informative. ���>��i&�@Br*�L��W?��;�6�Qb8L���`<3�.%hA ��� 1 Optimal Control based on the Calculus of Variations There are numerous excellent books on optimal control.
