Abstract
A quadrature coil for receiving NMR signals in magnetic resonance imaging employs as few as two substantially coplanar overlapping loops having sensitivity along perpendicular lines in a region of sensitivity. Each loop is sensitive to a fluctuating uniform magnetic field but is decoupled by a decoupling network. A common ground point shared between the two loops allows the combination of the signals produced by the two loops with a hybrid combiner without the coupling of the loops through the signal's grounds. A third loop may be added to the two loops to produce a third signal to further improve the signal-to-noise ratio of the coil.
