Phased array RF coils for high-resolution MRI of the inner ear and brain stem.

Abstract

OBJECTIVE The spatial resolution in MRI is predominantly limited by the available signal-to-noise ratio (S/N). To increase the S/N, a four coil phased array consisting of bilateral pairs of semioval coils was constructed for high resolution imaging of the temporal bone and brainstem. MATERIALS AND METHODS Coil sizes of 10 x 6 and 6 x 4.5 cm were tested… (More)
