Abstract: A radio frequency (RF) trap for a superconducting magnet apparatus includes an electromagnetic wave shield which includes a conductive shield member and is configured to surround an electric cable; and a circuit member which is provided in a portion of the electromagnetic wave shield, and includes a conductor circuit electrically connected to the conductive shield member in at least two positions. Two positions at which the conductive shield member is electrically connected to the conductor circuit are selectively adjusted so that a current path of the conductor circuit is adjustable according to the two positions at which electrical connections are made.

Abstract: A radio frequency (RF) surface coil and a magnetic resonance imaging (MRI) apparatus having the RF surface coil are provided. The RF surface coil includes a first cup unit and a second cup unit corresponding to a chest of an object, the first cup unit and the second cup unit being transformable to a shape of the chest. The RF surface coil further includes an RF coil element disposed on the first cup unit and the second cup unit.

Abstract: A head coil and a magnetic resonance imaging (MRI) apparatus employing the same. The head coil may increase a field of view by allowing a housing over the eyes of a patient to be closely fitted around the head of the patient. The head coil includes a plurality of radio frequency (RF) coil elements, a first housing, and a second housing configured to receive the head of a patient along with the first housing, wherein the first and second housings are changed or modified to have any of receiving spaces of different sizes to correspond to any of different head sizes of patients.
