Patent number: 11948288Abstract: Motion contaminated magnetic resonance (MR) images for training an artificial neural network to remove motion artifacts from the MR images are difficult to obtain. Described herein are systems, methods, and instrumentalities for injecting motion artifacts into clean MR images and using the artificially contaminated images for machine learning and neural network training. The motion contaminated MR images may be created based on clean source MR images that are associated with multiple physiological cycles of a scanned object, and by deriving MR data segments for the multiple physiological cycles based on the source MR images. The MR data segments thus derived may be combined to obtain a simulated MR data set, from which one or more target MR images may be generated to exhibit a motion artifact. The motion artifact may be created by manipulating the source MR images and/or controlling the manner in which the MR data set or the target MR images are generated.Type: GrantFiled: June 7, 2021Date of Patent: April 2, 2024Assignee: SHANGHAI UNITED IMAGING INTELLIGENCE CO., LTD.Inventors: Xiao Chen, Shuo Han, Zhang Chen, Shanhui Sun, Terrence Chen
