Prospective acquisition correction for head motion with image‐based tracking for real‐time fMRI
TL;DR: A novel technique called Prospective Acquisition CorrEction (PACE) for reducing motion‐induced effects on magnetization history is described and they showed a significant decrease of variance between successively acquired datasets compared to retrospective correction algorithms.

Method for operating a magnetic resonance imaging apparatus ensuring coincidence of images obtained in different examinations with respectively different positions of a subject
TL;DR: In this paper, a first scout dataset of the examination subject is produced and with reference to which at least one first slice of an examination subject to be imaged is determined, and a change in position between the first and the further scout dataset is identified.

System and method for lesion segmentation in whole body magnetic resonance images
Gozde Unal,Gregory G. Slabaugh,Tong Fang,Shawn Lankton,Valer Canda,Stefan Thesen,Shuping Qing +6 more
TL;DR: In this paper, the authors propose a method for lesion segmentation in 3D digital images, which includes selecting a 2D region of interest (ROI) from a 3D image, the ROI containing a suspected lesion, extending borders of the ROIs to 3D forming a volume of interest.
Book ChapterDOI
Automatic Labeling of Anatomical Structures in MR FastView Images Using a Statistical Atlas
TL;DR: A method for fast and automatic labeling of anatomical structures in MR FastView localizer images, which can be useful for automatic MR examination planning and for practical usage in clinical MR routine is presented.
Patent
Method for the implementation of a perfusion measurement with magnetic resonance imaging
TL;DR: In this article, a method for the implementation of a perfusion measurement with magnetic resonance imaging is presented, where image datasets of a region of an examination subject to be imaged and positioned in an imaging volume of a magnetic resonance apparatus are generated in a time sequence, positional changes of the region to be detected that occur relative to the imaging volume during the time sequence are acquired, and a correction of influences of the positional changes on the image datasets ensues according to the acquired positional changes.
