Synopsis

Keywords: Non-Array RF Coils, Antennas & Waveguides, Non-Array RF Coils, Antennas & Waveguides

Motivation: The demand for improving RF coil designs to maximize the potential of high-field MRI continues to grow. Exploring innovative RF coil elements holds the potential to improve RF coil performance and diagnostic image quality.

Goal(s): Our goal is to investigate the performance of a cycloid dipole antenna as a possible RF coil element for high-field MRI.

Approach: FDTD simulations were performed to compare the performance of a standard half-wavelength dipole at 7 T with two variations of the cycloid dipole.

Results: Cycloid dipole exhibits a shorter resonance structure, higher B1+ and B1+/√SAR10g_max efficiencies when compared to the standard dipole antenna.

Impact: The study introduces cycloid dipoles as potential MRI coil elements. This opens opportunities for future investigations to optimize cycloid antennas within specific MRI coil designs, improving clinical imaging quality.
