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.
