Patent number: 11494871Abstract: An apparatus comprises processing circuitry configured to receive a plurality of training image data sets and a plurality of predetermined displacements. The processing circuitry is further configured to use the training image data sets and predetermined displacements to train a transformation regressor in combination with a discriminator in an adversarial fashion by repeatedly alternating a transformation regressor training process in which the transformation regressor is trained to predict displacements, and a discriminator training process in which the discriminator is trained to distinguish between predetermined displacements and displacements predicted by the transformation regressor.Type: GrantFiled: November 18, 2020Date of Patent: November 8, 2022Assignee: Canon Medical Systems CorporationInventors: James Sloan, Owen Anderson, Keith Goatman

Patent number: 11379978Abstract: A medical image processing apparatus includes processing circuitry configured to apply a first trained model to input image data to obtain a first output based on the input data, where the input data includes clinical data. The processing circuitry is further configured to apply a second trained model to the input data to obtain a second output based on the input data, where the first trained model and the second trained model have been trained in dependence on a hierarchical relationship between the first output and the second output. The hierarchical relationship includes at least one of: a spatial hierarchy, a temporal hierarchy, an anatomical hierarchy, and a hierarchy of clinical conditions.Type: GrantFiled: July 14, 2020Date of Patent: July 5, 2022Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Owen Anderson, Aneta Lisowska, Alison O'Neil, Keith Goatman
