Publication number: 20120288174Abstract: The present invention provides an atlas comprising values representative of magnetic resonance properties of a magnetic resonance (MR) scan and optionally, prior probability data relating to tissue type. Further embodiments of the invention involve a system including an MR scanner and the atlas for use in alignment of an MR scan, such as a localizer scan, to obtain a specific geometry of the data acquired during a subsequent scan. Also, a system includes an MR scanner and the atlas for automatic segmentation of an MR scan. Methods of making and using the atlas and system are also provided.Type: ApplicationFiled: March 2, 2012Publication date: November 15, 2012Applicant: CORTECHS LABS, INC.Inventors: Anders Dale, Sebastian Gicquel

Patent number: 8191359Abstract: Systems, apparatus and methods that use a hidden Markov model to estimate motion of a sample under measurement and to reduce a motion-induced effect in the measurement. MRI systems and other sample measurement systems can be implemented based on motion sensing using the hidden Markov model. Recursive and non-recursive estimation processes are described.Type: GrantFiled: April 13, 2007Date of Patent: June 5, 2012Assignee: The Regents of the University of CaliforniaInventors: Nathan White, Anders Dale

Patent number: 8160319Abstract: Systems and techniques for reducing distortions in magnetic resonance images. In one aspect, machine-implemented method for reducing image distortion in magnetic resonance imaging (MRI) includes receiving a first MRI image and a second MRI image, estimating displacements of voxels between the first MRI image and the second MRI image by minimizing a cost function expressing a cost of the displacements, reducing distortion in an MRI image using the estimated displacements, and making the MRI image having reduced distortion available. The first MRI image and the second MRI image were acquired using different gradient fields.Type: GrantFiled: May 16, 2008Date of Patent: April 17, 2012Assignee: The Regents of the University of CaliforniaInventors: Dominic Holland, Anders Dale

Publication number: 20070090837Abstract: A system, method, software arrangement and computer-accessible medium for correcting for a motion of an object are provided. In this system, method, software arrangement and computer-accessible medium, the navigator data and map data can be obtained for the object. Then, the navigator data is compared with the map to generate comparison data. Thereafter, a translation and/or a rotation of the object is corrected in real-time as a function of the comparison data. The navigator can be preferably a clover leaf navigator. In one exemplary embodiment, a scanning sequence can be used to determine a position of the object. For example, this scanning sequence may include a signal portion which includes at least one radio frequency signal, a navigator portion which includes at least one clover leaf navigator, and a spoiler portion provided for reducing a signal magnitude of the scanning sequence. The navigator is provided for allowing a measurement of the rotation and/or the translation of the object.Type: ApplicationFiled: October 24, 2005Publication date: April 26, 2007Inventors: Andre Van Der Kouwe, Anders Dale

Patent number: 6952097Abstract: In a method and computer program product for operating a tomographic imaging apparatus, a standard measurement protocol is generated by displaying a planning representation of a standard object, defining a spatial position of a standard imaging area in the planning representation, and storing, as the standard measurement protocol for the standard object, a reference to the standard object and parameters of the standard imaging area. Such a standard measurement protocol can then be used in the slice position planning for an actual tomographic measurement, by obtaining data representing features of an examination object, corresponding to the standard object, determining a geometrical relation of the features of the examination object to features of the standard object, and generating an object-specific measurement protocol wherein the imaging area is positioned relative to the examination object by modification of the standard measurement protocol.Type: GrantFiled: October 22, 2003Date of Patent: October 4, 2005Assignee: Siemens AktiengesellschaftInventors: Oliver Schreck, Mike Müller, Martin Harder, Hans-Peter Hollenbach, Franz Schmitt, Ines Nimsky, Anders Dale, Andre Van Der Kouwe
