Patent number: 11723603Abstract: A system for scanning an object is provided. The system may include: a supporting table configured to support the object; a first signal conversion unit configured to receive one or more first signals associated with the object and convert the first signals into one or more second signals; and a signal receiver board configured to receive the one or more second signals. The first signal conversion unit may include a plurality of first signal receiving channels. Each first signal receiving channel may be configured to receive a first signal associated with a portion of the object. The supporting table and the signal receiver board may be configured to move relative to each other to cause the signal receiver board to receive at least one second signal corresponding to at least one first signal received by at least one target channel of the first signal receiving channels.Type: GrantFiled: June 28, 2021Date of Patent: August 15, 2023Assignee: SHANGHAI UNITED IMAGING HEALTHCARE CO., LTD.Inventors: Xiaolei Guan, Luosheng Zhou, Long Ma, Jianfan Zhou, Bo Li

Publication number: 20210196222Abstract: The present disclosure relates to systems and methods for reducing noise in an imaging system. The methods may include determining an imaging sequence for imaging a subject. When imaging the subject based at least on the imaging sequence, the imaging system may generate a first noise. The methods may further include obtaining, based on the imaging sequence, noise reduction data from a database. And the method may also include causing a generation device to produce a second noise based on the noise reduction data. The second noise may be configured to interfere with the first noise to reduce the first noise.Type: ApplicationFiled: December 30, 2020Publication date: July 1, 2021Applicant: SHANGHAI UNITED IMAGING HEALTHCARE CO., LTD.Inventors: Zhenbao LIU, Xiaolei GUAN, Haiyun HOU, Xiaopeng LUO, Mingchao WANG
