Magnetic Resonance Fingerprinting enables rapid
multi-parametric mapping. By interweaving multiple
transmit-channels into the fingerprinting sequence an
elegant parallel transmission framework can be
constructed. Forgoing uniform excitations, this
generalized MR fingerprinting framework circumvents a
pitched battle against the electro-dynamic interactions
that cause B1 artifacts in the traditional MR paradigm
while maintaining a tractable plug & play like
workflow. In this work we introduce the concept of
fingerprint compression, which enables even greater
acceleration factors while simultaneously speeding up
the reconstruction process. This is of particular
importance when using multiple transmit channels.
