Rf Coil Assembly And Method For Practicing Magnetization Transfer On Magnetic Resonance Imaging And Spectroscopy Systems

View page
US Patent:
7508212, Mar 24, 2009
Filed:
Aug 20, 2007
Appl. No.:
11/841201
Inventors:
Sean B. Fain - Madison WI, US
Matthew G. Erickson - Madison WI, US
Krishna N. Kurpad - Madison WI, US
James H. Holmes - Madison WI, US
Thomas M. Grist - Madison WI, US
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
G01V 3/00
US Classification:
324318, 324322
Abstract:
An RF coil assembly for an MRI system includes a resonator formed by a cylindrical shield and pairs of opposing conductive legs disposed symmetrically around a central axis and extending the axial length of the shield. One set of conductive leg pairs is tuned to operate at the Larmor frequency of C and another set is tuned to operate at the Larmor frequency of H. Drive circuitry operates the RF coil assembly to produce H spin magnetization which is transferred to C magnetization by the nuclear overhauser effect and to acquire MR data from the C spins. Multinuclear measurements can be made simultaneously at different Larmor frequencies.

Magnetic Resonance Imaging Rf Coil Decoupling Circuit

View page
US Patent:
7692427, Apr 6, 2010
Filed:
May 9, 2007
Appl. No.:
11/746504
Inventors:
Wonje Lee - Pewaukee WI, US
Krishna N. Kurpad - Middleton WI, US
Eddy B. Boskamp - Menomonee Falls WI, US
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
G01V 3/00
US Classification:
324322, 324318
Abstract:
A RF transmit coil decoupling circuit in a parallel drive configuration comprises a power amplifier and an output matching network to shim the Bfield in response to inhomogeneities therein. The separate coil segments in a transmit array are effectively decoupled from each other despite inherent mutual inductance between coil segments by the decoupling circuit. The output matching network forms a high impedance block seen by the coil elements, while it provides a load line impedance at the output of the power amplifier. The transmission line transformer in the output matching network suppresses higher order harmonics for clearer RF wave forms. It also dampen the Q factor of the output matching network allowing stable operation with a series tuned coil element.

Rf Coil Assembly For Magnetic Resonance Imaging And Spectroscopy Systems

US Patent:
7714581, May 11, 2010
Filed:
Mar 22, 2007
Appl. No.:
11/726643
Inventors:
Matthew G. Erickson - Madison WI, US
Sean B. Fain - Madison WI, US
Krishna N. Kurpad - Madison WI, US
James H. Holmes - Madison WI, US
Thomas M. Grist - Madison WI, US
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
G01V 3/00
US Classification:
324322, 324318
Abstract:
An RF coil assembly for an MRI system includes a resonator formed by a cylindrical shield and pairs of opposing conductive legs disposed symmetrically around a central axis and extending the axial length of the shield. Drive circuitry for each pair of opposing conductive legs includes a current balun that maintains substantially equal and opposite currents in the two conductive legs. Terminal susceptance elements are used to maintain maximum currents and minimum voltage at the midpoints of the conductive legs. Multinuclear measurements can be made simultaneously at different Larmor frequencies.

Voltage Standing Wave Suppression For Mr-Guided Therapeutic Interventions

View page
US Patent:
8412306, Apr 2, 2013
Filed:
Mar 27, 2007
Appl. No.:
11/728874
Inventors:
Krishna N. Kurpad - Madison WI, US
Orhan Unal - Madison WI, US
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
A61B 5/05
US Classification:
600423, 600411, 600424
Abstract:
A system and method of tracking a medical device and generating an image of a target area. The medical device includes a tracking device to create an imaging field-of-view that extends beyond the tip of the medical device while allowing the tip of the medical device to be visualized. The medical device further includes an imaging/visualization device to create an imaging field from the point of view of the medical device. A voltage standing wave suppression device is formed on the exterior surface of the medical device to prevent the formation of voltage standing waves and localized tissue heating. The voltage standing wave suppression device includes two cable traps spaced apart from one another with each cable trap being formed of a closely packed coiled region of a conductor extending the length of the medical device.

Multi-Mode Medical Device System And Methods Of Manufacturing And Using Same

View page
US Patent:
8457712, Jun 4, 2013
Filed:
Dec 30, 2005
Appl. No.:
11/322451
Inventors:
Orhan Unal - Fitchburg WI, US
Krishna N. Kurpad - Middleton WI, US
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
A61B 5/05
US Classification:
600411, 600407, 600410
Abstract:
A multi-mode medical device system and method of performing an interventional procedure. The multi-mode medical device system can be capable of MR internal imaging and of being tracked using an MRI system. The multi-mode medical device system can include a medical device, and an electrical circuit coupled to the medical device and electrically coupled to the MRI system. The electrical circuit can include a tracking device configured to transmit a signal to the MRI system indicative of the position of the tracking device relative to a roadmap image, and an imaging device electrically coupled to the tracking device and configured to internally image anatomical structures from the point of view of the medical device. The imaging device can be further configured to be visualized using MR imaging. Tracking the tracking device and internally imaging with the imaging device can be performed in a single pass of the multi-mode medical device system.
