Synopsis

Keywords: High-Field MRI, BrainThe clinical experience, especially for subjects with claustrophobia, is not friendly when using the conventional shielded birdcage head coils on the ultra-high field. The closed structure also does not better support motion detection and motion correction, and other MRI functional applications. In this work, an optimized Open-Face birdcage head coil were designed based on EM simulations. The transmit efficiency, B1 uniformity, and SAR efficiency of the facial open-window birdcage coil with different configurations and a conventional shielded birdcage coil are compared. Finally, an optimized Open-Face birdcage head coil was built and evaluated on a whole body 5T MRI scanner.
