Abstract
The invention concerns a birdcage resonator used as a transmitter and/or receiver coil in an NMR apparatus. The resonator comprises two ring-shaped conductors each of which is interrupted along its outer periphery by capacitors, the ring-shaped conductors being connected together by axial conducting strips. A plurality of axial conducting strips have their ends located between each pair of peripherally neighbouring capacitors. It is preferred when RF energy is coupled in or out between two conducting strips and when the ring-shaped conductors are shielded by shielding rings in the direction towards the sample. The birdcage resonator in accordance with the invention exhibits an improved RF field homogeneity at higher Q compared to conventional birdcage resonators.
