Coil Ringdown Suppression by Broadband Forward Compensation

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.
