摘要： In a method for analyzing acquired magnetic resonance images, an image series is provided that includes acquired magnetic resonance images of a slice of an object, picture elements of the acquired magnetic resonance images of the image series are fitted to generate a parameter map and an error map, the acquired magnetic resonance images are automatically segmented to generate image segments, histograms of the parameter map and the error map are generated based on the image segments, and the histograms are analyzed to generate an output of analysis results and/or generate a visualization including the parameter map, the error map, and the image segments. The acquired magnetic resonance images can have a variation of a contrast-determining acquisition parameter.

摘要： A method for reconstructing dynamic image data is described. In the method, raw data is acquired in a time-dependent manner from an examination region, wherein at least some of the raw data is assigned various values of movement parameters. First time-dependent image data based on acquired raw data is reconstructed. Furthermore, deformation fields based on the first image data are determined as a function of at least two time-dependent movement parameters. Based on the deformation fields, the raw data and the first image data, corrected image data is then generated. Furthermore, a reconstruction apparatus is described. Moreover, a magnetic resonance imaging system is described.

摘要： In a method and magnetic resonance apparatus for recording diagnostic measurement data of a heart of an examination object, the magnetic resonance apparatus is operated by a control sequence wherein an RF pulse excites nuclear spins with a flip angle of at least 60°, the diagnostic measurement data are recorded in a coordinate system independent of the heart, and the basic magnetic field produced by the magnetic resonance apparatus is smaller than 1.0 tesla.

摘要： Techniques are disclosed relating to the generation of a magnetic resonance (MR) image of a predetermined portion of a volume of an examination object. MR data of the portion may be acquired using echo trains in a first step and in a second step, with each of the echo trains acquiring MR data of a plurality of k-space lines. The plurality of k-space lines extend parallel to one another and perpendicular to a common plane such that per k-space line, one intersection point within a plane results. The MR image is then reconstructed using the acquired MR data.

摘要： Techniques are disclosed for a scan recommendation method is disclosed, wherein evaluation data comprising classification data are received, the classification data classifying anomalies detected in input data concerning the medical condition of a patient. Based on the evaluation data, an automatic determination of a next recommended MR protocol to be executed in accordance with an MR scan of the patient is performed. Further, a personal scan preparation method is disclosed and a medical imaging method is described, as well as a scan workflow performing method. For execution of the above-mentioned methods, a scan recommendation system, a personal scan preparation system, a medical imaging system, and a scan workflow performing system are also described.

摘要： In a method for automatic motion detection in medical image-series, a dataset of a series of images is provided. The images can be of a similar region of interest that are recorded at consecutive points of time. The method can further include localizing a target in the images of the dataset and calculating a position of the target in the images to calculate localization data of the target, and calculating movement data of a movement of the target of temporal adjacent images of the images based on the localization data.
