At high fields (e.g. 7T), RF head coils can have significant sensitivity in the neck and shoulder region, which creates aliasing artefacts when used with a head gradient coil. We present an RF coil design for 7T that achieves good SNR in the brain while minimising signal from the head and neck regions.
