Patent number: 10803354Abstract: A framework for cross-modality image synthesis. A first and second model may be trained using respective first and second pairs of complementary images and corresponding first and second ground truth images that represent first and second views of a region of interest. The first and second pairs of complementary images may be acquired by a first modality and the first and second ground truth images may be acquired by a second modality. A combinational network may further be trained to combine features from the first and second models. At least one synthetic second modality image may then be generated by passing current images through the trained first or second model and the combinational network, wherein the current images are acquired by the first modality and represent the first or second view of the region of interest.Type: GrantFiled: January 28, 2019Date of Patent: October 13, 2020Assignee: Siemens Healthcare GmbHInventors: Yu Zhao, Yimo Gao, Shu Liao, Liang Zhao, Zhennan Yan, Yiqiang Zhan, Xiang Sean Zhou

Patent number: 10730276Abstract: A vacuum system for film lamination, including a vacuum chamber module, a film-pressing module, a substrate susceptor module and a hot-plate heating module, is disclosed, wherein the film-pressing module includes a film-pressing platen, and the substrate susceptor module includes a substrate susceptor supported by a spring-loaded mechanism. During a film-lamination process, the film-pressing platen is actuated to move downwards to attach a laminating film onto a substrate, and the substrate susceptor is actuated to move downwards and finally rest on the hot-plate heating module. Therefore an adhesive glue disposed between the laminating film and the substrate can be thermally cured. After completing the film-lamination process, the film-pressing platen is actuated upwards so that the substrate susceptor also is actuated to move upwards to its initial position by a restoring force exerted by the spring-loaded mechanism.Type: GrantFiled: January 5, 2018Date of Patent: August 4, 2020Assignee: Maven Optronics Co., Ltd.Inventors: Chieh Chen, Chung-Shu Liao, Ping-Lin Wu, Hsiuwen Wang

Patent number: 10304198Abstract: A framework for automatic retrieval of medical images. In accordance with one aspect, the framework detects patches in a query image volume that contain at least a portion of an anatomical region of interest by using a first trained classifier. The framework determines disease probabilities by applying a second trained classifier to the detected patches, and selects, from the patches, a sub-set of informative patches with disease probabilities above a pre-determined threshold value. For a given patch from the sub-set of informative patches, the framework retrieves, from a database, patches that are most similar to the given image. Image volumes associated with the retrieved patches are then retrieved from the database. A report based on the retrieved image volumes may then be generated and presented.Type: GrantFiled: September 15, 2017Date of Patent: May 28, 2019Assignee: Siemens Healthcare GmbHInventors: Zhennan Yan, Yiqiang Zhan, Shu Liao, Yoshihisa Shinagawa, Xiang Sean Zhou, Matthias Wolf

Patent number: 9286688Abstract: Disclosed herein is a framework for segmenting articulated structures. In accordance with one aspect, the framework receives a target image, a reference image, statistical shape models, local appearance models and a learned landmark detector. The framework may automatically detect first centerline landmarks along centerlines of articulated structures in the target image using the learned landmark detector.

Patent number: 8888185Abstract: A motion platform having decoupled two axes adopts four modularized pneumatic bellows configured in an orthogonal arrangement. The pneumatic bellows can be independently controlled to cause the motion platform to be operated in one rotational degree of freedom with a frontward-and-backward swinging or a leftward-and-rightward swinging; or the pneumatic bellows can be synchronously controlled to cause the motion platform operated in two rotational degrees of freedom without being interfered with each other. Thus, the motion platform of the present disclosure is characterized with advantages of simplified mechanism, fewer components, convenient maintenance and reduced cost.Type: GrantFiled: November 23, 2012Date of Patent: November 18, 2014Assignee: INJOY Motion Corp.Inventor: Chung-Shu Liao
