Short summary
Hyperpolarization methods offer the possibility of overcoming the inherent sensitivity limits of nuclear magnetic resonance (NMR) given by the thermal Boltzmann spin distribution. The radio-frequency (RF) pulses to monitor the hyperpolarization process alter it by depleting the created magnetization. Possible corrections are simulated with a rate-equation model containing a single source and relaxation rate. The accuracy is demonstrated experimentally, enabling the use of larger flip angles.
