Patents by Inventor Jason Stephen Wiener

Jason Stephen Wiener 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).

  • Data-driven optimization of event acceptance/rejection logic
    Patent number: 9332952
    Abstract: In Positron Emission Tomography, a time window (260) and an energy window (225) are dynamically adjusted, based on an attenuation map, count rate, clinical application, discrimination tailoring, and/or offline discrimination tailoring. Detected radiation events are filtered using the dynamically adjusted energy and time windows into scattered events, random events, and true events. The true events are input to image reconstruction, correction, and error analysis.
    Type: Grant
    Filed: October 3, 2012
    Date of Patent: May 10, 2016

  • Adaptive calibration for tomographic imaging systems
    Patent number: 9299171
    Abstract: A method comprises: acquiring imaging data using a tomographic radiological imaging apparatus (10); updating a calibration (42, 52) based on current information about the imaging apparatus; calibrating the imaging data using the up-to-date calibration; and reconstructing the calibrated imaging data to generate an image. The updating may be based on a current state of an idle or parked imaging modality that is not used in acquiring the imaging data, or on a measurement acquired together with the imaging data, or on the imaging data itself. For cone-beam computed tomography (CBCT) imaging data, the updating may comprise determining an intensity scale based upon intensity of at least one air pixel measured during the acquiring of the CBCT imaging data and updating an air scan template (60) by the intensity scale.
