摘要： A method for performing phase encoded inside-out magnetic resonance imaging. The phase of the nuclear spin is advanced by applying a magnetic field gradient between application of each of several refocusing pulse sequences so that echoes are detected during refocusing pulse sequences for different phase advances. The echoes detected for each refocusing sequence are added together and averaged. An image is then generated from the averaged echoes, such as by Fourier transform techniques. In addition, a method is provided for eliminating ringing while measuring a nuclear magnetic resonance property of a volume of earth formation surrounding a borehole. The phase of the refocusing pulses is changed so that pairs of echoes in the echo train have opposite ringing phase. Echoes in the echo train having opposite ringing phase are added to cancel ringing in the echo train. The echo train can then be analyzed for amplitude and/or decay characteristics.

摘要： A nonaqueous, heat-cured, two-component coating has a combination of good scratch resistance and resistance to etching by acid rain and comprises a solvent-containing polyol component and a cross-linking component. The cross-linking component comprises at least one aliphatic and/or cycloaliphatic polyisocyanate having 2 to 6 NCO functional groups per molecule in which 0.1 to 95 mol % of the isocyanate groups of the polyisocyanate are reacted with an N-alkyl-3-aminopropyltrialkoxysilane and/or an N-aryl-3-aminopropyltrialkoxysilane. The weight ratio of the polyol to the cross-linking component in the coating is 6:1 to 1:2.

摘要： A method and a measuring-sequence-determining device for determining a measuring sequence for a magnetic resonance system based on at least one intra-repetition-interval time parameter are provided. During the determination of the measuring sequence in a gradient-optimization method, gradient-pulse parameters of the measuring sequence are automatically optimized to reduce at least one gradient-pulse-parameter maximum value. As a boundary condition in the gradient-optimization method, the intra-repetition-interval time parameter is kept constant at least within a specified tolerance value.

摘要： In a method and apparatus to reduce movement artifacts in magnetic resonance images an essentially unmoving area of a region to be imaged is located in a region of high sensitivity of a first group of individual local antennas, and a moving area is located in the region of high sensitivity of a second group of local antennas. Spatially coded magnetic resonance signals are received by a first group of the local antennas and are individually processed further. Spatially coded nuclear magnetic resonance signals are received by the second group of local antennas and are combined with a weighting, using weighting factors. The weighting factors are determined so as to reduce gradient of the weighted, combined, spatially dependent sensitivity of the local antennas of the second group.

摘要： A system receives cardiac cine MR images consists of multiple slices of the heart over time. A series of short axis images slices are received. Long axis images are also received by the system, wherein a base plane defined by landmark points is detected. An intersection of the base plane with a contour of a heart chamber is determined for a plurality of slices in the short axis image. A volume for each of the contour slices covering the heart chamber, including for contours that are limited by base plane intersections, is evaluated. All slice volumes are summed to determine a total volume of the chamber. In one embodiment the chamber is a left ventricle and the landmark is a mitral valve. An ejection factor is determined.

摘要： A set of image-space data is reconstructed from a set of k-space data. The set of image-space data is generated by minimizing a cost functional by an iterative non-linear conjugate gradient process. The iterative process may be accelerated by introducing k-space weighting to the cost functional. With proper choice of k-space weighting, a block-Toeplitz matrix is generated which permits use of Fast Fourier Transform techniques. An image is rendered from the set of image-space data.

摘要： In a method for imaging a periodically-moving subject region of a subject, an overview image data set is initially obtained that maps a movement of the subject region, at least two positions that the subject region assumes at corresponding points in time are marked in the overview image, further positions of the subject region at further points in time are interpolated from the marked positions and further points in time, and a subsequent diagnostic imaging of the moving subject region is implemented using the marked and interpolated positions.
