Abstract:
An open magnetic resonance apparatus which includes an examination region for receiving a subject oriented along a subject axis, a main magnet which generates a temporally constant main magnetic field in a direction orthogonal to the subject axis, an RF transmitter which transmits radio frequency pulses to a quadrature radio frequency coil to excite resonance in selected dipoles in the examination region such that the dipoles generate resonance signals at a characteristic resonance frequency, a quadrature radio frequency coil assembly which receives the resonance signals from the resonating dipoles, and a radio frequency receiver for demodulating the resonance signals received from the quadrature RF coil, the quadrature RF coil comprising:a plurality of parallel rung elements disposed orthogonal to the subject axis and parallel to the main magnetic field; electrical conductive ends connecting the plurality of rung elements; and a plurality of capacitive elements interrupting at least one of the rung elements and ends.
