David M. Shepard 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).

  • ARC-sequencing technique for intensity modulated ARC therapy
    Patent number: 7839974
    Abstract: The invention is directed to a radiation therapy method, and in particular, to a method of conducting an intensity modulated arc therapy (IMAT). The invention provides a planning technique that translates traditional static fixed-field IMRT plans into deliverable IMAT plans and allows IMAT to be realized as a routine clinical delivery technique.
    Type: Grant
    Filed: March 27, 2009
    Date of Patent: November 23, 2010
    Assignee: University of Maryland, Baltimore
    Inventors: David M. Shepard, Matthew A. Earl, Daliang Cao

  • Method for preparing a radiation therapy plan
    Patent number: 6560311
    Abstract: A method for determining a radiation treatment plan for a radiotherapy system providing multiple individual rays of intensity modulated radiation iteratively optimized the fluence of an initial set of such rays by a function that requires knowledge of only the prescribed dose and the dose resulting from the particular ray fluences. In this way, the need to store individual dose distributions of each ray are eliminated.
