  • High frequency large volume resonator
    Patent number: 6590393
    Abstract: The present invention provides magnetic resonance imaging coils for pursuing large volume images at high magnetic field strengths of 3 Tesla or higher. Also provided are methods of obtaining images by utilizing such magnetic resonance imaging coils. Specifically, the present invention provides a high field large volume resonator comprising a conductive cavity with segments of coaxial cable with exposed center conductors passing through, thereby creating a voltage node corresponding to the center of the conductive cavity. The cavity dimensions of the high frequency large volume resonator are sufficiently large to accommodate a human subject or other appropriate subject of similar size.
