Hyperpolarized gas MRI of lungs requires homogeneous RF excitation and high SNR for proper spin-density mapping with low flip angles. A dual loop T/R ¹²⁹Xe coil was designed and constructed to provide flexibility for a wide range of patient sizes while maintaining high transmit/receive homogeneity for hyperpolarized ¹²⁹Xe imaging and therefore provide high-quality images for identifying and quantifying functional pulmonary deficiencies. Electromagnetic field simulations were used to analyze excitation profiles.
