Notre Dame Patents

Collection Details Full Record

Description

This collection brings together all of the patents assigned to the University of Notre Dame from 1952 to the present, plus other selected patents prior to 1952. Each record includes a full-text searchable and accessible PDF document for the corresponding invention. The record also includes the present-day academic department with which the inventor was or would have been associated.

Why patents? According to the University’s IDEA Center, “Part of the University’s public service mission is to ensure that the results of its research are made available for public use and benefit. This is accomplished in many ways: through educating students, publishing results of research, and ensuring that inventions are developed into useful products and services for the benefit of the public.”

“Today, our research universities play an even more vital role in creating a better future—not only by educating close to 600,000 graduate students in science and engineering every year, but also, and critically, by performing more than 15% of U.S. R&D in 2011—and according to 2012 NSF data, accounted for the majority (53%) of national basic research. This research, some basic, some applied or ‘translational’ creates new technologies, new products and services, medicines, diagnostics — the list is long and impressive — but also, this research gives rise to entire new industries.” (David Winwood, “The Importance of Patents and Academic Technology Transfer,” March 26, 2015)

The collection also includes the most famous patent associated with Notre Dame, U.S. patent 1,811,959 from 1931, “Vinyl derivatives of acetylene and method of preparing the same” — in other words, synthetic rubber. Invented by Rev. Fr. Julius Nieuwland, CSC, and assigned to DuPont, this patent did, in fact, give rise to entire new industries. More about this invention may be found at the National Inventors Hall of Fame.

These patents are one more example of the University fulfilling Rev. Fr. Sorin’s vision of becoming a “powerful force for good.”

    Patent Number:
    US 9020230 B2
    Description:

    A method for reconstructing an image of an object that includes a plurality of image elements. The method includes accessing image data associated with a plurality of image elements, and reconstructing an image of the object by optimizing an objective function, where the objective function is optimized by iteratively solving a nested sequence of approximate optimization problems. The algorithm is composed of nested iterative loops, in which an inner loop iteratively optimizes an objective fun…

    Patent Number:
    US 9261467 B2
    Description:

    A system and method include acquisition of projection data from a scanned object, the set of projection data comprising a plurality of projection measurements. The system and method also include calculation of a set of modified statistical weights from the projection data, wherein a respective modified statistical weight of the set of modified statistical weights comprises a deviation from an inverse variance of a corresponding projection measurement of the projection data. The system and met…

    Patent Number:
    US 8787521 B2
    Description:

    A system and method include acquisition of a set of image data corresponding to a time period of data acquisition, the set of image data corresponding to a plurality of voxels, wherein each of the plurality of voxels corresponds to a distinct acquisition time within the time period of data acquisition. The system and method further include the modeling of the plurality of voxels as a function of time based on a plurality of kinetic parameters associated therewith and reconstruction of an imag…

    Patent Number:
    US 9460485 B2
    Description:

    A method includes obtaining spectral computed tomography (CT) information via an acquisition unit having an X-ray source and a CT detector. The method also includes, generating, with one or more processing units, using at least one image transform, a first basis image and a second basis image using the spectral CT information. Further, the method includes performing, with the one or more processing units, guided processing on the second basis image using the first basis image as a guide to pr…

  • Inventor(s):
    Guangzhi Cao, Jiang Hsieh, Jean-Baptiste Thibault, Jiahua Fan, Ken D. Sauer
    Patent Number:
    US 9538974 B2
    Description:

    Various methods and systems are provided for estimating and compensating for table deflection in reconstructed images. In one embodiment, a method for computed tomography (CT) imaging comprises reconstructing images from data acquired during a helical CT scan where table deflection parameters are estimated and the reconstruction is adjusted based on the table deflection parameters. In this way, images may be reconstructed without artifacts caused by table deflection.
