Abstract:
A birdcage resonator (109) for MR imaging, surrounds an examination volume and includes a plurality of rungs (1-16) arranged in parallel to a longitudinal axis of the examination volume. Each rung (1-16) includes a rung capacitance (Crung). Two end rings are arranged at the opposite ends of the rungs (1-16), each end ring includes a plurality of ring capacitances (Cring). Each ring capacitance (Cring) interconnects a pair of adjacent rungs (1-16). Each pair of adjacent rungs and the interconnecting ring capacitances (Cring) form a mesh of the birdcage resonator. The ring capacitances (Cring) and the rung capacitances (Cring) are proportioned so that: —the birdcage resonator (109) has a plurality of resonant modes that are tuned to the same resonance frequency, and the meshes of the birdcage resonator (109) are electromagnetically coupled. An MR device (101) includes the birdcage resonator.
