- RF MONO-DIPOLE HYBRID ARRAY ANTENNA RF COIL FOR MAGNETIC RESONANCE IMAGING

摘要

The present invention is a cylindrical body with an open lower surface; a plurality of mono-dipole antennas disposed along a surface of the cylinder body; and a capacitor (capacitor) electrically connecting the plurality of mono-dipole antennas on the upper surface of the cylinder body, wherein the plurality of mono-dipole antennas are spaced apart at a predetermined interval and arranged in a hybrid arrangement Phosphorus, relates to a magnetic resonance imaging device, in order to form a sufficiently uniform magnetic field in the ROI by improving the low magnetic field efficiency and SNR, which are the biggest drawbacks of the pulse wave blood flow velocity measurement method through MRI. is connected using a capacitor to reduce the interference between each channel with an electrical circuit technique such as a single ground, and to effectively form a magnetic field required for the ROI.
