WebA coil that produces an RF field with circular polarization. The RF power received from the RF power amplifier comes in two signals ( quadrature detection ), which have a phase difference of 90°. The RF transmit coil converts the power into a circularly polarized RF magnetic field. Quadrature coils can be used as both, transmit and/or receive coil. WebIn high-magnetic-field MRI, both valuable image contrast and undesirable artifacts associated with the magnetic susceptibility effects are significantly increased. The magnetic field distortion in and by the human body is described with computer modeling methods in the human head.
