Patent number: 12026877Abstract: The present disclosure provides a method, a device, and a non-transitory computer-readable storage medium for detecting a medical condition of an organ. The method includes obtaining 2D image sequences of the organ in a plurality of different directions and applying a plurality of classification branches to the 2D image sequences. Each classification branch receives a 2D image sequence of one direction and provides a classification result with respect to that direction. Each classification branch includes a convolutional neural network configured to extract first image features from the corresponding 2D image sequence and a recurrent neural network configured to extract second image features from the first image features. The method further includes fusing the classification results provided by the plurality of classification branches for detecting the medical condition.Type: GrantFiled: September 23, 2021Date of Patent: July 2, 2024Assignee: SHENZHEN KEYA MEDICAL TECHNOLOGY CORPORATIONInventors: Jinchen Li, Guang Li, Chengwei Sun, Kunlin Cao, Qi Song

Patent number: 8342044Abstract: Various embodiments disclose a flow cytometric apparatus comprising a flow chamber to be passed through by a sample in a row in sequence, a sample storage means for metering and storing the sample, a sample syringe for driving the sample into the flow chamber, a syringe-type injection-suction device comprising a sheath liquid syringe and a liquid-path switching means connected with it, and a control unit for controlling the operations of the sample syringe and the syringe-type the injection-suction means. In a sample charging stage, the injection-suction means feeds the sample into the sample storage means so that the sample is temporarily stored in it in a ready-to-use state, and in a sheath-liquid injection stage, the injection-suction means feeds the sheath liquid into the flow chamber to form a sheath flow. A flow cytometric method performed by the flow cytometric apparatus is also disclosed.Type: GrantFiled: February 8, 2010Date of Patent: January 1, 2013Assignee: Shenzhen Mindray Bio-Medical Electronics Co., Ltd.Inventors: Bingqiang Zhao, Quan Gan, Chengwei Sun
