For optimal performance an array should conform closely to the anatomy being imaged. Knee coils typically have rigid formers which must be large enough to accommodate most subjects, but which necessarily are not optimal for small ones. We present here a cylindrical surface coil array which can adapt in size while maintaining good tuning, match and decoupling. It is built on a trellis-like structure which controls the configuration and morphs the surface coils.
