BIRDCAGE TYPE RF RECEIVE COIL WITH SINGLE LEG CAPACITOR, AND THEREOF METHOD

The present invention relates to a birdcage type MRI reception end RF coil having a single leg capacitor and a method for manufacturing the same. The birdcage type MRI reception end RF coil having a single leg capacitor comprises a housing which is made of a hollowed cylindrical transparent plastic material; a coil sheet which is attached to the circumference of the side surface of the housing in a cylindrical shape, includes end coils formed in the upper end and the lower end in the horizontal direction and a plurality of coil legs (250) vertically connected to the end coil, and is patterned in a strip type on a flexible printed circuit board by forming gaps in the center of the coil legs and the end coils located among the coil legs; a capacitor which is mounted on the gaps formed in the coil legs and the end coils; and a detuning circuit which is installed in at least one end coil and changes impedance to be detuned. With the above simple structure and constitutions, the present invention is able to form a uniform internal magnetic field, generate a resonant frequency of a good quality and increase the receiving sensibility to provide the RF coil for an MRI system having high performance of improving an NMR imaging quality. Furthermore, the present invention provides a method for manufacturing the RF coil which is capable of improving the output stability of an electromagnetic element and is easy for a mass production.
