Zhuangli Liang 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).

  • Medical image processing
    Patent number: 8031927
    Abstract: In one aspect, the invention is a method of medical image processing. The method includes receiving data representing a medical image. The method also includes generating the medical image based on a model. The model characterizes the medical image as a composition of at least two components having processing constraints.
    Type: Grant
    Filed: December 28, 2005
    Date of Patent: October 4, 2011
    Assignee: The General Hospital Corporation
    Inventors: William C. Karl, Zhuangli Liang, Homer Pien, Thomas J. Brady
  • Medical image processing
    Patent number: 7689017
    Abstract: In one aspect, the invention is a method to reduce a blooming effect of a bright object in a medical image generated from a low-dose imaging system. The method includes characterizing an ideal image as a composition of a first component and a second component. The first component is characterized by a first function and the second component is characterized by a second function. The method also includes minimizing the first function and the second function using a smoothing process and generating the medical image based on the minimizing.
