We present a new approach of quickly measuring MR parameter maps by treating the quantitative MR problem as a dynamic system identification process. The system equations are inverted to match the response of the MR scanner to the data in time domain. Due to advances in numerical optimization and computing power, this approach has become possible and it is routinely applied, for instance, to seismology. For the first time, we apply it to MR and we recover all the desired parameters, for example: T1, T2, B1, B0, M0. Data acquisition takes just a few seconds.
