Zusammenfassung:The present invention relates to a wireless RF surface coil having an adjustable size for magnetic resonance imaging (MRI), which comprises: a body tube (110) having an injection hole (111) communicating with a flow path formed therein to constitute a closed loop; a lattice tube (120) having a lattice structure with at least one intersecting portion while a flow path communicating with the body tube (110) is formed in an inner space (S) formed by the body tube (110); at least one fixing member (130) fixed to the body tube (110) or the lattice tube (120) to block the flow path of the body tube (110) or the lattice tube (120); and conductive liquid contained in a flow path of the closed loop of the body tube (110) and the lattice tube (120) divided by the fixing member (130). Accordingly, the size of the coil can be adjusted in various ways according to a part of the human body. 본 발명은 크기를 자유롭게 조절이 가능한 자기공명 영상용 무선 RF 표면 코일에 관한 것으로, 내측에 형성된 유로와 연통되는 주입구(111)가 형성되어 폐루프를 구성하는 몸체 튜브(110)와; 상기 몸체 튜브(110)에 의해 형성된 내측 공간(S)에 상기 몸체 튜브(110)와 연통되는 유로가 형성되어 적어도 하나 이상의 교차 부위가 형성된 격자 구조를 갖는 격자 튜브(120)와; 상기 몸체 튜브(110) 또는 상기 격자 튜브(120)에 고정되어 상기 몸체 튜브(110) 또는 상기 격자 튜브(120)의 유로를 차단하게 되는 적어도 하나 이상의 고정부재(130)와; 상기 고정부재(130)에 의해 구획된 상기 몸체 튜브(110)와 상기 격자 튜브(120)의 폐루프 유로 구간에 충전되는 도전성 액체를 포함한다.
