Synchronization Of Wireless Transmitted Mri Signals In Mri System

View page
US Patent:
7123009, Oct 17, 2006
Filed:
Sep 22, 2005
Appl. No.:
11/233669
Inventors:
Greig C. Scott - Palo Alto CA, US
Assignee:
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
International Classification:
G01V 3/00
US Classification:
324311, 324314
Abstract:
In a MRI system having a FID detector unit and a computer unit for processing FID signals, phase errors introduced into the FID signal at the detector unit are corrected at the computer unit by transmitting a pilot signal from the computer unit to the detector unit, processing the pilot unit along with a detected FID signal at the detector unit, transmitting the processed signals to the computer unit, obtaining the pilot signal and FID signal at the computer unit, and combining the pilot signal and the FID signal whereby phase errors cancel.

Assignee:
m2m Imaging Corp. - Highland Heights OH
International Classification:
G01V 3/00
US Classification:
324322, 324318
Abstract:
A magnetic resonance imaging system includes a primary magnet and a secondary magnet operable to produce magnetic fields within a sample being imaged. The MRI system further includes at least one RF coil that is operable to receive electromagnetic frequencies from the sample. The RF coil is formed from tubing that serves as a cooling conduit through which flows a cooling fluid provided by a cooling source. The cooling fluid cools the RF coils to improve imaging of the sample.

US Patent:
8125270, Feb 28, 2012
Filed:
May 11, 2009
Appl. No.:
12/464010
Inventors:
Marta G. Zanchi - Palo Alto CA, US
Greig C. Scott - Palo Alto CA, US
Assignee:
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
International Classification:
H03F 1/22
US Classification:
330 69, 330149, 330150, 375295
Abstract:
An amplifier system providing improved Cartesian feedback is provided. A complex band pass error amplifier is provided. A quadrature up converter is connected to the complex band pass error amplifier so as to receive as input, output from the complex band pass error amplifier. An amplifier is connected to the quadrature up converter so as to receive as input, output from the quadrature up converter. A quadrature down converter is connected at or beyond the amplifier output so as to receive as input a signal proportional to that delivered by the amplifier as output to a load, wherein the complex band pass error amplifier is connected to the quadrature down converter so as to receive as a first input, output from the quadrature down converter and as a second input, a quadrature reference signal.

International Classification:
A61N 5/10
G01N 23/04
US Classification:
378 65, 378 63
Abstract:
The present invention provides a radiotherapy treatment apparatus that includes a treatment beam, a magnetic field disposed parallel collinear to the treatment beam, and a target that is disposed along the treatment beam. The treatment beam can be a charged particle beam, a proton beam, an electron beam, or a linear accelerator (Linac) beam. The magnetic field is from a magnetic resonance imager (MRI), a megavolt x-ray imager, or a kilovolt x-ray imager and is disposed to operate in coordination with operation of the treatment beam and to narrow the beam. The tumor is disposed to rotate with respect to the treatment beam and the magnetic field, or the treatment beam and the magnetic field are disposed to rotate up to 360 with respect to the target when mounted to a ring gantry. The apparatus can include a rotation angle dependent shim disposed to account for Earth's magnetic field.

US Patent:
20020013525, Jan 31, 2002
Filed:
May 22, 2001
Appl. No.:
09/863797
Inventors:
Greig Scott - Palo Alto CA, US
International Classification:
A61B005/05
US Classification:
600/410000
Abstract:
Transmission Line Techniques for MRI Catheter Coil Miniaturization and Tuning. The present invention provides a device and method for miniature and tunable MRI receiver coil for catheters that can be used in minimally invasive procedures and intravascular imaging. An MRI receiver coil for catheter procedures is provided having an impedance matching element that includes at least one miniature transmission line cable which are interconnected to construct the impedance matching element. In a particular embodiment, the miniature transmission line cables are constructed to make an inductance matching element defining an inductance L. In another particular embodiment, the miniature transmission line cable is a capacitance matching element defining a capacitance C. The present invention provides a system and method that allows fine-tuning locally with a higher signal-to-noise ratio. Transmission line cables also overcome the minimum size limits of fixed components. The shielded and balance techniques further reduce noise and improve safety.
