In this work combined methodologies for rapidly
acquiring parametric maps of the brain are described.
Several parameters in the brain, including: T1, T2, T2*,
magnetic susceptibility and proton density are
calculated, in addition to several machine distortion
parameters, including: B0 and B1 field inhomogeneity,
and coil profiles. The protocol time used to produce
these images was less than 26 minutes, and resulted in
whole brain coverage with 1 mm^3 isotropic resolution.
Collection of these key physiological and machine
distortion parameters will allow for advanced simulation
of the MR system.
