    摘要： A method for identifying a region of interest within a time sequence of images includes acquiring a time sequence of images comprising a plurality of image frames. Image segmentation is performed to segment a region of interest (ROI) from within each of the plurality of image frames of the time sequence of images. Manual edits are received for the ROI within one or more of the plurality of image frames. The manual edits are propagated to other image frames of the plurality of images. An extent to which each of the manual edits are propagated to other image frames is dependent upon a transformation function or deformation field used to propagate the manual edits and a weighing factor that is influenced by a distance in time between the other image frames and the frames that have been manually edited.

    摘要： In a method for image data acquisition of a region of interest in a subject with a magnetic resonance device, wherein, to establish the field of view, a minimal geometric shape encompassing the subject to be acquired and/or the surface of the subject is determined automatically from previously acquired localizer exposures as aliasing information for each exposure, at least one slice plane is determined for the acquisition of the region, and the phase coding direction and/or the extent of the field of view in the phase coding direction is determined for every slice plane using the aliasing information.

    摘要： In a method and magnetic resonance tomography apparatus for triggered implementation of a measurement (composed of partial measurements) in the magnetic resonance tomography apparatus, at least one image data set is determined from the data acquired within the scope of the partial measurements, and for triggering a reference point of the movement phase of the movement is used. The image data set is acquired in segments; the reference point is detected by a control device independent of a partial measurement, and the partial measurement following the detected reference point is conducted depending on the independently detected reference point. The wait time that specifies the interval from the end of the partial measurement to the beginning of the next partial measurement is adapted depending on the point in time of detection.

    摘要： In a method for representation of the heart in a magnetic resonance system at least one MR overview image of the heart is acquired. An image plane with a predetermined position relative to the magnetic resonance system is selected for this overview image. The acquired MR overview image is displayed and a number of marking points are established in the displayed overview image. Further image planes for representation of the heart are calculated using some of the established marking points. Further MR images are acquired in the calculated image planes.
