31P magnetic resonance spectroscopy signal sensitivity is low due concentrations of the nucleus and magnetic field inhomogeneity from currently available commercial surface coils. Dual-tuned (1H/31P) birdcage coils are advantageous in that they create a very homogeneous B1 field inside the coil. The practicality of building a dual-tuned coil, however, can be troublesome due to many factors such as coil structure (e.g., # of legs/rings, dimensions) and biological objects to be imaged. In this abstract, the homogeneity comparisons for the 8-leg, 16-leg, and the 24-leg, 4-ring low-pass birdcage coils are presented with the presence of simulated human head and thigh modules.
