Abstract
Hybrid circuitry () for operatively coupling a radio frequency drive signal () with a quadrature coil () is configurable in one of at least two coil modes of a group consisting of: (i) a linear I channel mode in which an I channel input port () is driven without driving a Q channel input port (); (ii) a linear Q channel mode in which the Q channel input port is driven without driving the I channel input port; (iii) a quadrature mode in which both the I and Q channel input ports are driven with a selected positive phase difference; and (iv) an anti quadrature mode in which both the I and Q channel input ports are driven with a selected negative phase difference. A temporal sequence of the at least two coil modes may be determined and employed to compensate for Binhomogeneity.
