Patent number: 10092199Abstract: A magnetic resonance method and system are provided for generating real-time motion-corrected perfusion images based on pulsed arterial spin labeling (PASL) with a readout sequence such as a 3D gradient and spin echo (GRASE) image data acquisition block. The real-time motion correction is achieved by using a volumetric 3D EPI navigator that is provided during an intrinsic delay in the PASL sequence, which corrects for motion prospectively and does not extend the image data acquisition time as compared to a similar non-motion-corrected imaging procedure.Type: GrantFiled: April 1, 2015Date of Patent: October 9, 2018Assignees: Siemens Healthcare GmbH, The General Hospital CorporationInventors: Keith Aaron Heberlein, Himanshu Bhat, Matthew Dylan Tisdell, Andre Jan Willem Van Der Kouwe

Patent number: 9940713Abstract: A method for MRI inter-scan motion correction includes performing (i) an anatomical localizer scan of a region of interest (ROI) to identify anatomical landmarks defining orientation of a surrounding field-of-view (FOV); (ii) an inter-scan motion reference scan of the ROI to acquire a reference inter-scan dataset indicating a reference navigator location in the ROI; and (iii) scans of the ROI to acquire k-space data. Prior to one or more of the scans, a motion correction process is performed that includes (a) performing an inter-scan motion tracking scan to acquire a tracking inter-scan dataset indicating an updated reference navigator location; (b) determining an estimation of inter-scan patient motion based on a comparison between the reference inter-scan and tracking inter-scan datasets; and (c) updating the FOV relative to the landmarks based on that estimation. Images of the ROI may be generated using the k-space data acquired with each of the scans.Type: GrantFiled: November 15, 2016Date of Patent: April 10, 2018Assignees: Siemens Healthcare GmbH, The General Hospital CorporationInventors: Himanshu Bhat, Keith Aaron Heberlein, Thomas Beck, Martin Harder, Andre Jan Willem Van Der Kouwe, Matthew Dylan Tisdall

Publication number: 20170016972Abstract: A magnetic resonance (MR) method and system are provided for generating real-time prospective motion-corrected images using fast navigators. The real-time motion correction is achieved by using a 2D EPI navigator that is obtained using a simultaneous multi-slice blipped-CAIPI technique. The navigator parameters such as field of view, voxel size, and matrix size can be selected to facilitate fast acquisition while providing information sufficient to detect rotational motions on the order of several degrees or more and translational motions on the order of several millimeters or more. The total time interval for obtaining and reconstructing navigator data, registering the navigator image, and providing feedback to correct for detected motion, can be on the order of about 100 ms or less. This prospective motion correction can be used with a wide range of MR imaging techniques where the pulse sequences do not have significant intervals of “dead” time.Type: ApplicationFiled: July 13, 2015Publication date: January 19, 2017Inventors: Himanshu Bhat, Keith Aaron Heberlein, Stephen Farman Cauley, Matthew Dylan Tisdall, Kawin Setsompop, Andre Jan Willem Van Der Kouwe

Patent number: 8446149Abstract: A system for parallel image processing in MR imaging uses multiple MR imaging RF coils to individually receive MR imaging data representing a slice of patient anatomy. An MR imaging system uses the multiple RF coils to acquire corresponding multiple image data sets of the slice. A coil selection processor determines a prioritized ranking of the multiple RF coils by ranking individual coils of the multiple RF coils based on correlation with remaining coils of the multiple RF coils. The correlation being determined by determining degree of correlation of image data sets acquired by respective coils of the multiple RF coils. The coil selection processor selects a subset of the multiple RF coils using the ranking. An image generator generates a composite MR image using image data sets provided by the selected subset of the multiple RF coils excluding image data sets provide by remaining coils of the multiple RF coils.Type: GrantFiled: April 13, 2010Date of Patent: May 21, 2013Assignee: Siemens Medical Solutions USA, Inc.Inventor: Keith Aaron Heberlein
