  • Radio frequncy (RF) body coil and method for tuning an RF body coil for magnetic resonance imaging
    Patent number: 9297867
    Abstract: A radio frequency (RF) body coil includes a first end ring, a second end ring, a plurality of rungs connected between the first and second end rings, at least one shim holder coupled to the first end ring, and a RF shim configured to be at least partially inserted within the shim holder, the RF shim being repositionable within the shim holder to vary an operational frequency of the RF body coil. A magnetic resonance imaging system and a method of tuning the RF body coil are also described.
    Type: Grant
    Filed: January 5, 2012
    Date of Patent: March 29, 2016
    Assignee: General Electric Company
    Inventors: Bijay Shah, Ricardo Becerra, Masahiro Fujimoto, Zhentian Xie
  • Distributed capacitance radio frequncy (RF) coil and magnetic resonance imaging system including the same
    Patent number: 9157971
    Abstract: A radio frequency (RF) birdcage coil includes a first distributed capacitance end ring, a second distributed capacitance end ring, and a plurality of rungs connected between the first and second end rings, wherein at least one of the first and second distributed capacitance end rings includes a substrate having a first side and a second side, a first plurality of conductors formed on the first side, a second plurality of conductors formed on the second side, and an insulating material deposited on the first side such that the insulating material substantially covers the first plurality of conductors.
