Abstract: Techniques are described for providing at least one assessment indicator of an image quality of at least one magnetic resonance image, which comprises: providing at least one magnetic resonance image for assessing the image quality, wherein the providing is made to a quality unit; determining at least two different quality metrics of the at least one magnetic resonance image, wherein the quality unit comprises two or more quality modules, and each of the two or more quality modules is designed to determine one of the two or more different quality metrics, and providing the two or more quality metrics to an assessment unit; ascertaining the at least one assessment indicator by means of the assessment unit, wherein the at least one assessment indicator is ascertained from the two or more different quality metrics; and providing the at least one assessment indicator.

Abstract: Systems and Methods that identify the effect of motion during a medical imaging procedure. A neural network is trained to translate motion induced deviations of a coil-mixing matrix relative to a reference acquisition into a motion score. This score can be used for the prospective detection of the most corrupted echo trains for removal or triggering a replacement by reacquisition.

Abstract: The disclosure relates to a computer implemented method for magnetic resonance imaging. The method includes: receiving at least a first and a second subset of k-space data as radio frequency signals emitted from excited hydrogen atoms of a subject; sampling the first and second subset of k-space data; choosing the first subset of k-space data as a base subset of k-space data; estimating motion parameters of the second subset of k-space data against the base subset of k-space data; and correcting the second subset of k-space data based on the estimated motion parameters of the second subset of k-space data. The motion parameters of the second subset of k-space data are parameters of a non-linear motion estimating function representing a motion of the subject between receiving the first subset of k-space data and receiving the second subset of k-space data.

Abstract: A method for post processing and displaying a three-dimensional angiography image data set of a blood vessel tree of a patient, wherein two-dimensional display images are rendered from the angiography image data set and displayed, wherein two display images are rendered from the angiography image data set using viewing directions forming an angle suited for stereoscopic perception of the display images and both display images are simultaneously displayed on a display screen in a display presentation that causes each display image to be viewed by one eye of a person viewing the display screen.
