    摘要： In a method and apparatus to detect incorrect MR data in k-space representing MR signals acquired from an examination subject with at least two acquisition coils, MR data are acquired to generate at least one raw data set with each of the at least two acquisition coils and a check is made, for at least one k-space point, as to whether the MR data acquired for this k-space point should be replaced or not. In the event that the check yields that the MR data acquired for the at least one k-space point should be replaced, the MR data are replaced with reconstructed MR data that are based on at least two of the acquired raw data sets.

    摘要： A patient positioning device has an electromagnetically transparent transfer plate for positioning an examination subject, and at least one patient bed. The electromagnetically transparent transfer plate can be disposed on the patient bed for imaging an examination region of the examination subject with a first imaging device. For imaging the examination region of the examination subject with the second imaging device that has an electromagnetic localization device, the electromagnetically transparent transfer plate is disposed above the electromagnetic localization device. An imaging system and a corresponding method for medical imaging make use of such a patient position device.

    摘要： In a computerized method and magnetic resonance (MR) system for the supplementation of acquired MR data, at least one supplemented MR data set is determined from multiple acquired, reduced MR data sets that can be acquired with an accelerated acquisition method (such as partially parallel acquisition method, ppa) in which k-space is undersampled. The acquisition can thereby take place in parallel with multiple acquisition coils. In the method and system, a reconstruction kernel is applied to the multiple acquired, reduced MR data sets in order to determine a reconstructed MR data set for an acquisition coil. The reduced MR data set acquired with the acquisition coil is reused in this reconstructed MR data set. The reuse takes place by a combination with weighting with the respective variances.

    摘要： In a magnetic resonance (MR) system and method to separate an MR system-dependent phase influence from a subject-dependent phase influence in phase values of an MR phase image data set of an examination subject, to which two different tissue types with different resonance frequencies make a signal contribution, the system-dependent phase influence is determined by selecting a contour around a region shown in the MR phase image data set, calculating the system-dependent phase influence in this region with the assumption that the spatial curve of the background phase corresponds to a harmonic or quasi-harmonic function, and subtracting the system-dependent phase influence from the acquired phase image data set to determine the subject-dependent phase influence.
