B₁⁺ and E field inside a birdcage coil with and without a high-dielectric tube insert were investigated by finite difference time domain method. The high-dielectric insert can help to increase B₁⁺ field and decrease E field, which means high-dielectric insert has potential to increase signal to noise ratio.
