Patent number: 11547368Abstract: In a method and system, a medical imaging modality and the parameters to be deployed for the determined imaging modality are determined to produce an image of an examination object using the determined imaging modality and the determined parameters. Information from the preliminary examination(s) of the examination object can be automatically classified to generate classification results corresponding to interfering influence(s) resulting from the production of the image. The classification results can be analyzed to evaluate the classification results. The medical imaging modality and the parameter(s) is determined, based on the evaluated results, to minimize an influence of the interfering influences of the classification results in image(s) of the examination object generated using the determined medical imaging modality and the determined one or more parameters. The image(s) may then be generated using the determined medical imaging modality and the determined parameter(s).Type: GrantFiled: May 16, 2019Date of Patent: January 10, 2023Assignee: Siemens Healthcare GmbHInventor: Mario Zeller

Patent number: 11474171Abstract: The present invention is directed to a system and method for performing tissue, preferably bone tissue manipulation. The system and method may include implanting markers on opposite sides of a bone, fractured bone or tissue to facilitate bone or tissue manipulation, preferably in-situ closed fracture reduction. The markers are preferably configured to be detected by one or more devices, such as, for example, a detection device so that the detection device can determine the relative relationship of the markers. The markers may also be capable of transmitting and receiving signals. An image may be captured of the bone or tissue and the attached markers. From the captured image, the orientation of each marker relative to the bone fragment may be determined. Next, the captured image may be manipulated in a virtual or simulated environment until a desired restored orientation has been achieved. The orientation of the markers in the desired restored orientation may then be determined.Type: GrantFiled: March 24, 2020Date of Patent: October 18, 2022Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Robert Frigg, Stuart Weikel, Stefan Schwer, Geoffrey Flexner, Ross Jonathan Hamel

Patent number: 11375914Abstract: A method for producing an image representative of the vasculature of a subject using a MRI system includes the acquisition of a signal indicative of a subject' cardiac phase. During each heartbeat of the subject, image slices of a volume covering a region of interest (ROI) within the subject are acquired by applying a volume-selective venous suppression pulse to suppress (a) venous signal for an upper slice in the ROI; (b) venous signal for slices that are upstream for venous flow in the ROI; and (c) background signal from the upstream slices. Next, a slice-selective background suppression pulse is applied to suppress background signal of the upper slice. Following a quiescent time interval, a spectrally selective fat suppression pulse is applied to the entire volume to attenuate signal from background fat signal. Then, a simultaneous multi-slice acquisition of the upper slice and the upstream slices is performed.Type: GrantFiled: November 19, 2019Date of Patent: July 5, 2022Assignees: Siemens Healthcare GmbH, NorthShore University HealthsystemInventors: Shivraman Giri, Robert R.

Patent number: 11328185Abstract: A system and method for performing speckle correlation flow cytometry (SCFC). By subtracting out the stationary background when shining light through a sample (e.g., a vessel within a biological tissue), light only scattered by the desired targets (e.g., cells) can be captured and different types of targets (e.g., cells) can be distinguished by the autocorrelation of the speckle pattern. In this way, the targets (e.g., cells) can be classified and counted based on the features of their speckle correlations. The technique can be applied not only for noninvasive, label-free, in vivo CTC counting but also for counting other types of blood cells such as white blood cells or red blood cells.Type: GrantFiled: July 2, 2018Date of Patent: May 10, 2022Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGYInventors: Edward H.

Patent number: 11317896Abstract: An ultrasound diagnosis apparatus includes a calculating unit, an obtaining unit, a determining unit, and a controlling unit. By using a plurality of pieces of three-dimensional ultrasound image data in a time series corresponding to a three-dimensional region including a myocardium of a subject, the calculating unit calculates first movement information indicating a movement of the myocardium by tracking a movement of a region of interest that corresponds to the myocardium and that is set in each of the plurality of pieces of three-dimensional image data. The obtaining unit obtains direction information indicating a direction of a myocardial fiber in the myocardium. The determining unit determines second movement information indicating a movement of the myocardium with respect to the direction of the myocardial fiber, on the basis of the first movement information and the direction information. The controlling unit causes a display unit to display the second movement information.Type: GrantFiled: November 3, 2017Date of Patent: May 3, 2022Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Yasuhiko Abe, Tetsuya Kawagishi
