In magnetic resonance imaging (MRI), the electrical performance of the RF coil is critical to achieve sufficient signal to noise ratio (SNR). In this work, the variation of performance of a plane and a flexible coil over a saline and a humanlike phantom is proposed. In order to evaluate the RF sensitivity of these flexible devices, we performed both an electrical characterization of the coil performances...
Recently developed superparamagnetic scaffolds for bone tissue engineering are still a complex object to deal with. Thanks to the possibility of controlling them remotely and directing therapeutic action in a non-invasive way, this work deals with the necessity of a clear definition and quantification of the field gradient, the forces and velocity it could exert on magnetic nanocarriers in a static...
An evaluation of the present approach to the design of birdcage RF coils for RMI, based on periodic lumped circuit, has been performed. It appears that, for coils bigger than λ/6, a more accurate model is required, to reduce the trial-and-error tuning of the coil.
