Patent number: 11361849Abstract: Individual computer diagnostic support (CDS) systems are coupled to a ‘global’ CDS system, each of the CDS systems using the same learning system or the same learning system technique. Training and testing cases from each of the individual CDS systems are provided to the global CDS system, and the global CDS system uses these training cases to produce learning system parameters based on the training cases. Having more training cases than any of the individual CDS systems, the parameters provided by the global CDS system offer a higher quality diagnostic output than any of the individual CDS systems. The learning system parameters at the global CDS system may be provided to each of the individual CDS systems, to update the parameters of the individual CDS systems' learning system. The global CDS may also refine and/or adjust the structure of the embodied learning systems.Type: GrantFiled: November 10, 2014Date of Patent: June 14, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Yinhui Deng, Xiaomin Li, Xiaolin Gu, Vijay Thakur Shamdasani, Ying Wu

Patent number: 11116479Abstract: An ultrasonic diagnostic imaging system and method acquire a sequence of image data as a bolus of contrast agent washes into and out of the liver. The image data of contrast intensity is used to compute time-intensity curves of contrast flow for points in an ultrasound image. Time-dependent data is calculated from the data of the time-intensity curves which, in a described implementation, comprise first and second derivatives of the time-intensity curves. A color map is formed of the time-dependent data or the polarities of the data and displayed in a parametric image as a color overlay of a contrast image of the liver.Type: GrantFiled: January 2, 2018Date of Patent: September 14, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Xiaolin Gu, Yinhui Deng, Xiaomin Li, Vijay Thakur Shamdasani

Patent number: 11000262Abstract: An ultrasonic diagnostic imaging system produces contrast enhanced images which are processed differently during different stages of contrast agent wash-in. During an initial stage of contrast wash-in, imaging is done using pixels processed by maximum intensity detection, to better reflect the rapid change in contrast intensity. During a later stage of contrast wash-in, time averaged processing is used to diminish the effects of noise and motion on the pixel values. During an intermediate period of peak enhancement, a combination of both pixel values processed by both techniques is used. In another aspect, a wash-in period can be characterized by an appearance stage, a growth stage and a peak stage, in which contrast pixel data is adaptively processed in different ways during these periods.Type: GrantFiled: August 19, 2016Date of Patent: May 11, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Xiaolin Gu, Yinhui Deng, Xiaomin Li, Vijay Thakur Shamdasani, Ying Wu

Patent number: 10762631Abstract: The present invention proposes an apparatus and method for characterizing a tissue in a first region of a subject. The apparatus comprises a receiving unit (210) for receiving ultrasound data of the tissue in the first region and ultrasound data of a predetermined target reference tissue of said subject; a deriving unit (220) for deriving a subject-specific model of the target reference tissue on the basis of the ultrasound data of the target reference tissue; and a characterizing unit (230) for determining a match between tissue in the first region and the target reference tissue on the basis of the subject-specific model and ultrasound data of the tissue in the first region. Unlike conventional tissue characterization based on a large cohort of patient data, the proposed subject-specific model is personalized for the specific subject without any generalization, resulting in higher sensitivity and/or accuracy.Type: GrantFiled: December 16, 2016Date of Patent: September 1, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jingping Xu, Yinhui Deng, Xiaomin Li, Ying Wu

Publication number: 20190365344Abstract: An ultrasonic diagnostic imaging system and method acquire a sequence of image data as a bolus of contrast agent washes into and out of the liver. The image data of contrast intensity is used to compute time-intensity curves of contrast flow in the hepatic artery, the portal vein, and at one or more regions of interest in the liver. The time-intensity curve of contrast flow in the hepatic artery is scaled to the time-intensity curve of contrast flow in a region of interest to produce time-intensity curve data representing the flow of blood at the region of interest due to arterial flow. The time-intensity curve data representing the flow of blood at the region of interest due to arterial flow is subtracted from the time-intensity curve of contrast flow in the region of interest to produce time-intensity curve data representing the flow of blood at the region of interest due to venous flow.Type: ApplicationFiled: November 9, 2017Publication date: December 5, 2019Inventors: Xiaolin Gu, Yinhui Deng, Xiaomin Li, Vijay Thakur Shamdasani
