Abstract: A radiofrequency transducer assembly includes an antenna structure of the birdcage type. This antenna structure has longitudinally extending segments, which are arranged in a cylindrical configuration around a center axis, and at least one transversally oriented circular electrical coupling between the longitudinally extending segments. An electrically conductive shield surrounds the antenna structure of the birdcage type. The radiofrequency transducer assembly comprises a pair of electrically conductive bridges between a longitudinally extending segment of the antenna structure and the electrically conductive shield, which thereby jointly form an inductive loop.
