Publication number: 20230384406Abstract: A magnetic resonance imaging (MRI) system includes an internet protocol (IP) communication system for communicating IP-based communication data, an audio/video output, and an audio/video source. The MRI system also includes an audio/video/IP gateway device with multiple non-IP interfaces operable to receive and output audio/video data. The non-IP interfaces use non-IP protocols, while an IP interface connected to the communication system uses a predefined audio/video IP protocol. A controller is operable to convert received audio/video data between the non-IP and IP protocols, output converted audio/video data via the IP interface in IP protocol, and output converted audio/video data via the non-IP interfaces using the corresponding non-IP protocol.Type: ApplicationFiled: May 31, 2023Publication date: November 30, 2023Applicant: Siemens Healthcare GmbHInventors: Philipp Höcht, Gilbert Yammine, Felix Wolf, Dieter Faust, Jens Gühring, Stefan Schönwälder

Patent number: 8879852Abstract: A reconstructed image is rendered of a patient by a processor from a set of undersampled MRI data by first subtracting two repetitions of the acquired data in k-space to create a third dataset. The processor reconstructs the image by minimizing an objective function under a constraint related to the third dataset, wherein the objective function includes applying a Karhunen-Loeve Transform (KLT) to a temporal dimension of data. The objective function under the constraint is expressed as arg minf{??(f)?1 subject to ?Af?y?2??}. The reconstructed image is an angiogram which may be a 4D angiogram. The angiogram is used to diagnose a vascular disease.Type: GrantFiled: October 28, 2011Date of Patent: November 4, 2014Assignee: Siemens AktiengesellschaftInventors: Ti-chiun Chang, Mariappan S.

Patent number: 8805045Abstract: 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.Type: GrantFiled: September 29, 2011Date of Patent: August 12, 2014Assignee: Siemens AktiengesellschaftInventors: Christoph Guetter, Jens Gühring, Marie-Pierre Jolly, Arne Littmann, Manuela Rick, Michaela Schmidt, Hui Xue

Patent number: 8682054Abstract: A method and system for propagation of myocardial infarction from delayed enhanced magnetic resonance imaging (DE-MRI) to cine MRI is disclosed. A reference frame is selected in a cine MRI sequence. Deformation fields are calculated within the cine MRI sequence to register the frames of the cine MRI sequence to the reference frame. A DE-MRI image having an infarction region is registered to the reference frame of the cine MRI sequence. The DE-MRI image may be registered to the infarction region using a hybrid registration algorithm that unifies both intensity and feature points into a single cost function. Infarction information in the DE-MRI image is then propagated cardiac phases of the frames in the cine MRI sequence based on the registration of the DE-MRI image to the reference frame and the plurality of deformation fields calculated within the cine MRI sequence.Type: GrantFiled: November 15, 2011Date of Patent: March 25, 2014Assignee: Siemens AktiengesellschaftInventors: Hui Xue, Yixun Liu, Christoph Guetter, Marie-Pierre Jolly, Jens Gühring

Patent number: 8675942Abstract: A reconstructed image is rendered from a set of MRI data by first estimating an image with an area which does not contain artifacts or has an artifact with a relative small magnitude. Corresponding data elements in the estimated image and a trial image are processed, for instance by multiplication, to generate an intermediate data set. The intermediate data set is transformed and minimized iteratively to generate a reconstructed image that is free or substantially free of artifacts. In one embodiment a Karhunen-Loeve Transform (KLT) is used. A sparsifying transformation may be applied to generate the reconstructed image. The sparsifying transformation may be also not be applied.Type: GrantFiled: October 25, 2011Date of Patent: March 18, 2014Assignees: Siemens Aktiengesellschaft, National Institutes of HealthInventors: Ti-chiun Chang, Mariappan S.
