Patents by Inventor Steven Niederer

Steven Niederer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20200297284
    Abstract: Techniques are disclosed related to using anatomical mask data acquired via magnetic resonance imaging (MRI) scans to train a convolutional neural network (CNN). The training may include the verification of cardiac scar tissue locations data obtained from the anatomical mask data with a reliable system for doing so, such as ground truth data from enhanced cardiac MRI late gadolinium enhanced (LGE) scans. Once the CNN is adequately trained using the anatomical mask data, the CNN may be used to identify cardiac scar tissue from image data obtained from medical imaging modalities other than MRI.

  • Publication number: 20190298213
    Abstract: Embodiments of the invention provide a method and apparatus that allow for a personalised heart tissue model to be generated, that models heart tissue electrophysiology behaviour at a personalised level, based upon activation measurements of an individual subject's heart in response to a number of predefined pacing protocols. The activation measurements are collected using a catheter placed onto the subject's heart, which is then paced via the catheter in accordance with the pacing protocols, and activation times of the heart tissue recorded. The activation measurements are used to generate a personalised tissue model, for example, by parameter matching the activation measurements with a large number of predefined sets of activation measurements, to determine the best-fit set; the best-fit set is then used as a personalised heart tissue model in a two or three-dimensional simulation of heart tissue activation in response to simulated stimulation.
