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.
