As more advanced 7T MRI technology continues to emerge, the development of a wider anatomical range of RF coils has become a greater priority. In an effort to take advantage of the greater spatial resolution and higher SNR at 7T, a 12-rung birdcage transmitter and 28-channel receive-only array coil has been developed. To overcome the challenges associated with the shorter wavelength within the human body at 7T, several novel design strategies have been utilized.
