摘要: A volume MR phased array was constructed with two coils placed anteriorly and posteriorly. Data acquired simultaneously from the four on a phantom were combined into single image having signal-to-noise ratio 80% better than that body coil. Additional comparisons of four-coil two-coil Helmholtz pair same overall dimensions show how variations signal amplitude phase in individual affect composite SNR. Images male female pelvis demonstrate improved SNR can be used to reduce number excitations, decrease field view, increase echo time, or slice thickness. © 1991 Academic Press. Inc.
