Patent number: 11933870Abstract: For detecting motion in MR imaging, a regression model, such as a convolutional neural network, is machine trained. To generalize to MR imagers, MR contrasts, or other differences in MR image generation, the regression model is trained adversarially. The discriminator for adversarial training discriminates between classes of the variation source (e.g., type of MR imager or type of contrast) based on values of features learned in the regression model for detecting motion. By adversarial training, the regression model learns features that are less susceptible or invariant to variation in image source.Type: GrantFiled: June 19, 2019Date of Patent: March 19, 2024Assignee: Siemens Healthineers AGInventors: Silvia Bettina Arroyo Camejo, Benjamin L.

Patent number: 11934555Abstract: Systems and methods facilitate privacy-preserving data curation in a federated learning system by transmitting a portion of a potential data sample to a remote location. The portion is inspected for quality to rule out data samples that do not satisfy data curation criteria. The remote examination focuses on checking the region of interest but maintains privacy as the examination is unable to parse any other identifiable subject information such as face, body shape etc. because pixels or voxels outside the portion are not included. The examination results are sent back to the collaborators so that inappropriate data samples can be excluded during federated learning rounds.Type: GrantFiled: September 28, 2021Date of Patent: March 19, 2024Assignee: Siemens Healthineers AGInventors: Youngjin Yoo, Gianluca Paladini, Eli Gibson, Pragneshkumar Patel, Poikavila Ullaskrishnan
