APPARATUS FOR MAGNETIC RESONANCE IMAGING HAVING ELLIPTICAL BIRDCAGE SHAPE FOR IMPROVEMENT OF MAGNETIC FIELD UNIFORMITY AND EFFICIENCY IN WHOLE-BODY RF COIL

摘要

Magnetic resonance image acquisition apparatus according to an embodiment of the present invention is an elliptical column-shaped magnetic resonance that is perpendicular to the ellipses corresponding to the upper and lower surfaces of the virtual elliptical column, and is provided to be parallel to each other along the side of the virtual elliptical column. An image acquisition apparatus comprising: a plurality of high-frequency coils for transmitting and receiving a high-frequency magnetic field through a high-frequency coil including a leg coil having any one of a linear shape and a shape separated from a central region; a tuning capacitor for adjusting the surface current distribution of the high-frequency coil; and an operation port for applying a voltage to the high-frequency coil.
