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： 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.

摘要： A long RF pulse is segmented into a plurality of RF pulses segments with nuclei spin refocusing pulses provided after each RF pulse segment to maintain phase coherence off resonance and decrease nuclei spin sensitivity to magnetic field inhomogeneity. The refocusing pulses are preferably 180.degree. rectangular pulses. Magnetic gradient segments associated with the RF pulse segments have supplemental gradients at the beginning and at the end of the gradient segment to ensure that the position in k-space for the segment corresponds to the k-space position of the gradient waveform before division into segments.

摘要： A module, included in an electrophotographic printer, for making toner images by a method in which transfer current for electrostatic transfer of toner images to receiver members is adjusted to compensate for ambient variations of toner charge-to-mass ratio (q/m). A predetermined functional relationship between transfer current and a control voltage parameter is utilized. Magnitudes of the control voltage parameter are derived from voltage measurements relating to creation of toner control patches on a photoconductive image-recording member included in a modular electrophotographic printer. Control voltage magnitude is linearly dependent on q/m. The functional relationship, which is characterized by three experimentally determined parameters, is co-optimized for providing efficient transfer of toner images and for minimizing back-transfer of toner away from a receiver member in a transfer station included in the module.
