  • Patent number: 11246555
    Abstract: Methods and systems are provided for dual energy imaging. In one embodiment, a method for a dual energy imaging system comprises determining a first tube potential and a second tube potential according to a size of a subject, and controlling the dual energy imaging system with the first tube potential and the second tube potential to generate lower energy x-rays and higher energy x-rays respectively to image the subject. In this way, image quality may be increased while minimizing dose during dual energy imaging of a particular imaging subject.
    Type: Grant
    Filed: May 17, 2019
    Date of Patent: February 15, 2022
    Assignee: GE Precision Healthcare LLC
    Inventors: Jiahua Fan, Zhoubo Li, Mingye Wu, Ryan Lemminger, Priti Madhav, Rajeshwari Karthikeyan

  • Patent number: 6868292
    Abstract: A method and system of controlling devices with digitally stored content. Devices such as home electronic appliances, lighting systems, heating, ventilating and air conditioning (HVAC) equipment, home security systems and home entertainment systems are controlled from a single, centralized device. A set top box (STB) stores scripts that include program content for controlling the operation of a plurality of these devices from the STB. A user of the STB selects the desired scripts, and the STB accesses the selected scripts from storage based on a triggering mechanism such as time, content, event, etc. The STB selectively controls operation of certain devices designated in the script. The method provides ease of control over multiple and diverse devices, applications and media within a user's own home environment, with more functionality and flexibility than currently available.
