Patent number: 11176188Abstract: A visualization framework based on document representation learning is described herein. The framework may first convert a free text document into word vectors using learning word embeddings. Document representations may then be determined in a fixed-dimensional semantic representation space by passing the word vectors through a trained machine learning model, wherein more related documents lie closer than less related documents in the representation space. A clustering algorithm may be applied to the document representations for a given patient to generate clusters. The framework then generates a visualization based on these clusters.Type: GrantFiled: January 9, 2018Date of Patent: November 16, 2021Assignee: Siemens Healthcare GmbHInventors: Halid Ziya Yerebakan, Yoshihisa Shinagawa, Parmeet Singh Bhatia, Yiqiang Zhan

Patent number: 10698981Abstract: The disclosure relates to method and device for determining at least a portion of an anatomy from a set of medical images. Thereafter, the image acquisition protocol associated with the medical images is determined automatically based on the determined anatomy. The image acquisition protocol is automatically determined by extracting one or more features associated with the medical images characterizing the acquisition protocol. Thereafter, the medical images are classified based in the features. Further, the medical images are assigned with an acquisition protocol label based on the classification of the medical images. The medical images are displayed with the respective protocol labels. Further, medical images acquired with an identified image acquisition protocol at different time instances are displayed for comparative analysis.Type: GrantFiled: December 22, 2016Date of Patent: June 30, 2020Assignee: Siemens Healthcare GmbHInventors: Parmeet Singh Bhatia, Amit Kale

Patent number: 10685438Abstract: A framework for automated measurement. In accordance with one aspect, the framework detects a centerline point of a structure of interest in an image. A centerline of the structure of interest may be traced based on the detected centerline point. A trained segmentation learning structure may be used to generate one or more contours of the structure of interest along the centerline. One or more measurements may then be extracted from the one or more contours.Type: GrantFiled: June 25, 2018Date of Patent: June 16, 2020Assignee: Siemens Healthcare GmbHInventors: Fitsum Aklilu Reda, Yiqiang Zhan, Parmeet Singh Bhatia, Yoshihisa Shinagawa, Luca Bogoni, Xiang Sean Zhou

Patent number: 10580159Abstract: A framework for coarse orientation detection in image data. In accordance with one aspect, the framework trains a learning structure to recognize a coarse orientation of the anatomical structure of interest based on training images. The framework may then pass one or more current images through the trained learning structure to generate a coarse orientation of the anatomical structure of interest. The framework then outputs the generated coarse orientation of the anatomical structure of interest.Type: GrantFiled: January 23, 2018Date of Patent: March 3, 2020Assignee: Siemens Healthcare GmbHInventors: Fitsum Aklilu Reda, Parmeet Singh Bhatia, Yiqiang Zhan, Xiang Sean Zhou

Patent number: 9462987Abstract: The embodiments relate to a method and device for determining plaque deposits in coronary arteries. According to the method, a coronary angiography radiography image of a subject is obtained using an imaging modality. The obtained radiography image is calibrated for further analysis of the radiography image. Image processing techniques such as thresholding and histogram equalization are applied on the radiography image to extract vessel tree structure for analysis. Further, an inner lumen width and an outer vessel width are computed based on the processed radiography image. Further, a level of plaque deposition is determined based on the inner lumen and outer vessel dimensions. Further, the result based on the analysis is displayed to the user. The result includes the level of plaque deposits within the lumen on the vascular structure and possible risks posed by the plaque deposits to a subject.Type: GrantFiled: December 4, 2014Date of Patent: October 11, 2016Assignee: Siemens AktiengesellschaftInventors: Yogesh Bathina, Parmeet Singh Bhatia, Rajendra Prasad Jadiyappa, Amit Kale
