Abstract
An RF field generator and detector comprising an RF coil having an inductance and at least one conductor which includes at least first and second separated parts arranged to form stray capacitance between them, capacitors for impedance matching which are connected to the RF coil, and a balanced-to-unbalanced transformer by which a balanced load composed of the RF coil and the capacitors is coupled to an unbalanced RF transmitter and receiver, the stray capacitance being adjusted thereby to equivalently reduce the inductance of the RF coil.
