4. excitation An MRI term for the delivery—i.e., induction or transfer—of energy into spinning nuclei via radio-frequency pulse(s), which bumps the nuclei into a higher energy state. By producing a net transverse magnetisation, an MRI system can evoke a response from the excited system.

6. Excitation, in physics, the addition of a discrete amount of energy (called excitation energy) to a system—such as an atomic nucleus, an atom, or a molecule —that results in its alteration, ordinarily from the condition of lowest energy (ground state) to one of higher energy (excited state).
