摘要： In a magnetic resonance method and apparatus for time-resolved acquisition of magnetic resonance data in an examination region of a magnetic resonance imaging scanner, an object being examined is placed on a table and is continuously moved through the examination region, magnetic resonance signals are acquired from the examination region while the object being examined is continuously moved with the table through the examination region and prior to the acquisition of magnetic resonance signals, a phase coding that corresponds to a position in k-space, for the purpose of sampling k-space, is carried out. An interruption of the movement of the table takes place at a predetermined table position, and the acquisition of magnetic resonance signals from an examination region is continued over the course of a predetermined time period, while the table (13) is at rest in the predetermined position. At least while the table is at rest, the phase coding takes place such that acquisitions are made in alteration of a predetermined number of magnetic resonance signals for filling a first region of k-space with magnetic resonance data and a predetermined number of magnetic resonance signals for filling a second region of k-space with magnetic resonance data.

摘要： A transfer management system receives a request to transfer an amount of funds from a transferring account maintained by a transferring bank to a receiving account maintained by a receiving bank. The transfer management system determines whether the transferring bank maintains an intermediate transferring account, and whether the receiving bank maintains an intermediate receiving account. If the transferring bank maintains an intermediate transferring account and the receiving maintains an intermediate receiving account, the transfer management system transmits to a transferring bank system of the transferring bank an intra-bank transfer request. The intra-bank transfer request is to transfer the amount of funds from the transferring account to the intermediate transferring account. Additionally, the transfer management system transmits an intra-bank transfer request to a receiving bank system of the receiving bank to transfer the amount of funds from the intermediate receiving account maintained by the receiving bank to the receiving account.

摘要： In a method and magnetic resonance (MR) system to generate an MR phase contrast angiography image of an examination subject, velocity-dependent phase information is impressed on moving spins in the examination subject by switching additional bipolar coding gradients that are in addition to the basic phase coding and readout gradients. For the creation of the MR phase contrast angiography images, the MR signals of the examination subject are read out in raw data space with a non-Cartesian acquisition pattern during a readout gradient. The additional bipolar coding gradients switched such that they proceed along a coordinate system that corresponds to the non-Cartesian acquisition pattern, and such that a coordinate axis of this coordinate system proceed along the readout gradient.

摘要： A system orders acquisition of frequency domain components representing MR image data for storage in a storage array (e.g., k-space). A storage array of individual data elements stores corresponding individual frequency components comprising an MR dataset. The array of individual data elements has a designated center and individual data elements individually have a radius to the designated center. A magnetic field generator generates a magnetic field for use in acquiring multiple individual frequency components corresponding to individual data elements in the storage array. The individual frequency components are successively acquired in an order in which radius of respective corresponding individual data elements increases and decreases as the multiple individual frequency components are sequentially acquired during acquisition of an MR dataset representing an MR image. A storage processor stores individual frequency components acquired using the magnetic field in corresponding individual data elements in the array.

摘要： In a method for a rapid determination of spatially resolved magnetic resonance relaxation parameters in an area of examination, a preparation pulse is radiated into the area of examination. During the relaxation of the longitudinal magnetization, spatially encoded magnetic resonance signals are acquired at a minimum of two different points in time using a fast magnetic resonance sequence. At each inversion time, an image data record is reconstructed from the magnetic resonance signals, which are elastically registered to each other. From the recorded image data records, values of magnetic resonance relaxation parameters are spatially accurately determined.

摘要： A method to create magnetic resonance images of a predetermined imaging volume within an examination subject with a magnetic resonance system includes the following steps: Localize an inflow that supplies the imaging volume. Form a specific volume that at least partially includes the predetermined imaging volume and that is adapted to the inflow such that the specific volume has a recess into the specific volume at the inflow, via which recess at least a partial segment of the inflow is removed from the specific volume. Saturate or invert the magnetization of the specific volume by means of the magnetic resonance system. Detect measurement signals from the imaging volume. Create the MR images of the imaging volume by means of the measurement signals.

摘要： In a method to generate magnetic resonance (MR) images of an examination subject, MR signals are detected simultaneously with multiple coils, each coil having its own coil characteristic. In the detection of the MR signals, raw data space is incompletely filled with MR signals; with raw data space being undersampled in a central raw data region with a coherent acquisition pattern that is composed of a spatially repeating set of raw data points; and raw data space outside of the central raw data region is sampled with an incoherent acquisition pattern. The MR image is reconstructed from the detected MR signals, step-by-step in an iterative reconstruction procedure using a reconstruction matrix A, starting from an initial estimate; wherein the reconstruction matrix has continuing information about the coil characteristics with which the MR signals were detected.
