  • US Patent:
    7236816, Jun 26, 2007
  • Filed:
    Apr 24, 2002
  • Appl. No.:
    10/131601
  • Inventors:
    Ananda Kumar - Baltimore MD,
    Ergin Atalar - Columbia MD,
    Ogan Ocali - Sunnyvale CA,
  • Assignee:
    Johns Hopkins University - Baltimore MD
  • International Classification:
    A61B 5/055
  • US Classification:
    600411, 600423, 600562, 600567
  • Abstract:
    Herein is disclosed a magnetic resonance imaging antenna, including an inner conductor, an outer shield slideably displaceable with respect to the inner conductor, and an insulator electrically insulating the inner conductor from the outer shield. Herein is disclosed a biopsy needle antenna, including a magnetic resonance imaging antenna, having an outer shield, and an inner conductor electrically insulated from the outer shield by a dielectric; and a biopsy needle electrically connected to the inner conductor and electrically insulated from the outer shield by the dielectric. Herein is disclosed a method of obtaining a sample with magnetic resonance imaging guidance, including providing a sampling needle magnetic resonance imaging antenna, advancing the antenna to a structure from which the sample is to be taken, detecting magnetic resonance data by the antenna, and coupling the sample to the antenna.

  • Method Of Magnetic Resonance Analysis Employing Cylindrical Coordinates And An Associated Apparatus

    view source
  • US Patent:
    6031375, Feb 29, 2000
  • Filed:
    Nov 26, 1996
  • Appl. No.:
    8/979121
  • Inventors:
    Ergin Atalar - Columbia MD
    Ogan Ocali - Santa Clara CA
  • Assignee:
    The Johns Hopkins University - Baltimore MD
  • International Classification:
    G01V 300
  • US Classification:
    324307
  • Abstract:
    A method of magnetic resonance imaging employs cylindrical coordinates and in one embodiment has an elongated catheter which is operatively associated with an RF pulse transmitting antenna and an RF pulse transmitting body coil. A main magnetic field is imposed on the region of interest. Circumferential phase encoding is accomplished by applying an initial RF pulse from either the catheter antenna or the body coil and subsequently applying an initial series of RF pulses with the source alternating between the antenna and the body coil. Radial phase encoding is effected by applying a first RF pulse which in a second embodiment is followed by a second RF pulse. A longitudinal gradient magnetic pulse is applied in the region of interest to spatially encode magnetic resonance signals. The cylindrical coordinate imaging is obtained by combining the circumferential phase encoding information the longitudinal magnetic encoding information with or without the radial phase encoding information. Other embodiments not employing catheter antennas employ two antennas with non-uniform phase profiles with the pulse sequences employed with the antennas.
  • Enhanced Safety Coaxial Cables

  • US Patent:
    6284971, Sep 4, 2001
  • Filed:
    Nov 24, 1999
  • Appl. No.:
    9/449027
  • Inventors:
    Ergin Atalar - Columbia MD
    Ogan Ocali - Santa Clara CA
  • Assignee:
    Johns Hopkins University School of Medicine - Baltimore MD
  • International Classification:
    H01B 718
  • US Classification:
    174 36
  • Abstract:
    A coaxial cable which may be a magnetic resonance imaging coaxial cable is designed for enhanced safety so as to reduce the risk of excessive heating or burns to a user. The cable has an elongated axially oriented inner conductor and an axially oriented outer shield conductor in spaced relationship with respect thereto with a first dielectric material disposed therebetween. The outer shield conductor has an annular inner shield portion and segmented outer shield portions which are electrically connected to the inner shield portion. In certain preferred embodiments, a second dielectric material having a higher dielectric constant than the first dielectric material is disposed between the inner shield portion and the segmented outer shield portions. In one embodiment, an electrically conductive element extends between the segmented outer shield portions and the inner shield portion and terminates in spaced relationship therewith. In another embodiment, a capacitor may be introduced between the inner shield portion and the segmented outer shield portions.
