摘要： In a method and a device for phase-sensitive flow measurement of a volume segment of an examination subject using a magnetic resonance (MR) system, the volume segment is coded for imaging of this volume segment and a phase coding of the volume segment to code flow information of the volume segment is implemented. MR data are read out from the volume segment and the MR data are evaluated in order to generate an image of the volume segment with flow information. The phase coding to code the flow information is thereby independent of gradients which are used for spatial coding of the volume segment.

摘要： For the generation of a magnetic resonance (MR) image of a predetermined volume segment of a living subject, a tracking factor is determined for each of different regions of the volume segment, from which the position of the respective region can be determined depending on a position of a moving area of the subject. MR image data of the volume segment are acquired for different positions of the moving area. The position of the moving area is calculated depending on the position and the tracking factor of the respective region, and the MR image data of the respective region are reconstructed using the MR image data of the volume segment corresponding to the calculated position of the moving area. The MR image of the predetermined volume segment is generated as a combination of the constructed MR image data of the regions.

摘要： In a method of a magnetic resonance system and a method and computer-readable storage medium for the operation thereof to acquire magnetic resonance image data of an examination subject, wherein magnetic resonance system has a number of subsystems and a control device, a number of adjustment measurements to adjust at least one subsystem for making a medical diagnostic data acquisition are implemented through the control device. In these adjustment measurements, an adjustment volume associated with the appertaining adjustment measurement is taken into account that encompasses at least one region of a body containing the examination subject. For this purpose, markings established by the control device within image data of the examination subject and characterizing the spatial occupation (position and orientation) and/or a dimension of the examination subject are determined. Based on these markings the spatial occupation and extent of an adjustment volume for an adjustment measurement are determined automatically by the control device.

摘要： For imaging a volume segment by means of a magnetic resonance system, of the volume segment is transferred into a dynamic steady state relative to the magnetization by means of the magnetic resonance system. The following steps are repeatedly executed until the volume segment has been completely measured. The slice is excited by means of the magnetic resonance system. MR signals of the slice are read out. The slice is offset in an overlapping manner such that an overlap range is created by the slice before the offset and the slice after the offset, the overlap range being a predetermined percentile of both the slice before the offset and the slice after the offset.

摘要： The embodiments disclosed herein relate to a method for generating time-resolved images of an examination object, which executes a cyclical movement, and to a magnetic resonance device, and a computer program product herefor. According to a first aspect, at least one spatial magnetization pattern with spatial magnetization differences is generated during a magnetization of the examination object. Furthermore, magnetic resonance signals of the examination object are acquired after generating the spatial magnetization pattern throughout at least one cycle of the cyclical movement. At least one k-space is undersampled here during the acquisition of the magnetic resonance signals. Time-resolved images are generated based on the acquired magnetic resonance signals.
