Latest Patents

Zhen Yao's latest patents revolve around the optimized design of RF shields used in MRI systems. These RF shields are crucial as they can experience gradient field induced eddy currents and RF field induced eddy currents. Such eddy currents can lead to undesirable heating of the RF shield. The design goals for these shields include achieving a balance between gradient field transparency and RF field opacity. Yao's innovative methods involve identifying specific gradient and RF fields that induce eddy currents. If a region on the RF shield is found where the desired heating attribute is not met, he proposes making a pattern of axial and azimuthal cuts in the shield. This approach effectively reduces gradient eddy current heating while maintaining the necessary RF shielding.
