摘要： A method for automatically measuring currents induced on conducting structures positioned in the bore of a magnetic resonance imaging (“MRI”) scanner using a single magnetic resonance image is provided. A conductive structure is positioned within the bore of the MRI scanner during imaging. When the MRI system is transmitting an RF field, a current is induced in the conductive structure. The current creates a magnetic field at the Larmor frequency, which couples to the RF magnetic field in the vicinity of the conductive structure. The modified magnetic field results in an artifact being generated in phase images. The artifact in the phase image is then analyzed to determine the current induced in the conductive structure.

摘要： The present invention discloses a method for determining the position and/or orientation of a catheter or other interventional access device or surgical probe using phase patterns in a magnetic resonance (MR) signal. In the method of the invention, global two-dimensional correlations are used to identify the phase pattern and orientation of individual microcoils, which is unique for each microcoil's position and orientation. In a preferred embodiment of the invention, tracking of interventional devices is performed by one integrated phase image projected onto the axial plane and a second image in an oblique plane through the center of the coil and normal to the coil plane. In another preferred embodiment, the position and orientation of a catheter tip can be reliably tracked using low resolution MR scans clinically useful for real-time interventional MRI applications. In a further preferred embodiment, the invention provides real-time computer control to track the position of endovascular access devices and interventional treatment systems, including surgical tools and tissue manipulators, devices for in vivo delivery of drugs, angioplasty devices, biopsy and sampling devices, devices for delivery of RF, thermal, microwave or laser energy or ionizing radiation, and internal illumination and imaging devices, such as catheters, endoscopes, laparoscopes, and related instruments.

摘要： A method and system for determination of oxygen saturation in blood flowing in a vessel using magnetic resonance (MR). An MR image sequence is acquired with different echo time (TE) encoding, and different Fourier velocity encoding (FVE). A Fourier transformation is applied along the velocity dimension to determine a velocity distribution of tissue signals in each voxel of the image sequence. Tissue signals indicative of moving tissues are separated from tissue signals indicative of static tissue, based on the velocity distribution. Oxygen saturation in blood may then be determined using only the tissue signals indicative of flowing blood.

摘要： A beverage container for use with a drinking cup for dividing the cup into at least two individual beverage containing cells, each of which forms a discrete beverage container separate from the other. The beverage container comprises a semi-cylindrical, vertically tapered device, sized and shaped for mating insertion into a conventional tapered drinking cup. The beverage container includes a side wall having a top rim forming an opening, and a bottom. The side wall includes a curved, vertically tapered first side wall portion and a generally planar, vertically tapered second side wall portion. An elongated flexible tab is connected on one end thereof along a curved portion of the beverage container rim and folds over the rim of the cup upon insertion. The tab includes indicia for identifying the particular type, flavor, or brand of beverage contained within the beverage container portion of the drinking cup. The present invention thus allows a consumer to enjoy more than one flavor of beverage from a single cup, or, alternatively, allows a consumer to share a drink with a companion in a sanitary manner while allowing the consumer and companion to each consume his or her beverage of choice.
