ABSTRACT:
An MRI/MRS magnetic coil system is disclosed wherein the isolation between the coils can be adjusted to decrease or virtually eliminate the coupling between quadrature magnetic resonance imaging coils in order to optimize orthogonality between the coils. The adjustment allows the use of flexible coils which may be conformed to image specific anatomical regions. The RF characteristics of the coils are controlled by variable capacitors. The capacitors are controlled by a remote automatic controller which functions to adjust the RF characteristics of the coils until an optimal orthogonality and signal to noise ratio is achieved between and by the coils.
