Patent number: 11204408Abstract: The disclosure relates to a system and method for correcting inhomogeneity in an MRI image. The method may include the steps of: acquiring a first set of k-space data, acquiring a second set of k-space data, generating the convolution kernel of the first set of k-space data based on the first set of k-space data and the second set of k-space data, performing inverse Fourier transform on the convolution kernel of the first set of k-space data to obtain an inversely transformed convolution kernel of the first set of k-space data, and generating a corrector based on the inversely transformed convolution kernel of the first set of k-space data. The method may be implemented on a machine including at least one processor and storage.Type: GrantFiled: March 13, 2020Date of Patent: December 21, 2021Assignee: SHANGHAI UNITED IMAGING HEALTHCARE CO., LTD.Inventors: Yu Ding, Renjie He

Patent number: 11022667Abstract: The disclosure relates to a system and method for generating or using a synthesizing filter in image reconstruction. The method may include: acquiring a calibration data set including a plurality of data points, determining a first calibration region in the calibration data set, the first calibration region including a matrix having a plurality of data points, the plurality of data points includes a first data point at the center of the first calibration region, constructing a first relationship between the first data point and the data points in the first calibration region, and generating a synthesizing filter based on the first relationship. The first data point is at the center of the first calibration region. The method may be implemented on at least one machine each of which has at least one processor and storage. The generated synthesizing filter may be stored in the storage in electronic form as a data file.Type: GrantFiled: June 29, 2017Date of Patent: June 1, 2021Assignee: SHANGHAI UNITED IMAGING HEALTHCARE CO., LTD.Inventors: Yu Ding, Renjie He
