Coil ringdown due to the high Q resonance of NMR
detectors limits the speed at which the system can
switch from high power transmission to sensitive signal
acquisition and is a consequence of the narrowband
behaviour of the coil. We present an analytic broadband
pulse design approach to shorten the ringdown by
precompensating the Q of the coil with no excess peak
power requirements, no additional SAR deposition and no
changes to the existing RF coil hardware.
