  • Method of CT perfusion imaging and apparatus for implementing same
    Patent number: 7933377
    Abstract: A CT system includes a scintillator array having a first length in an axial direction of the CT system, the scintillator array includes a plurality of scintillator cells along the first length. The CT system includes a controller configured to repeatedly position a subject fore and aft along the axial direction and over a second length of the CT system, the second length greater than the first length, energize an x-ray source to emit x-rays toward the subject while the subject is being repeatedly positioned, and obtain non-uniform projection data of the subject from the scintillator array, the non-uniform projection data comprising the x-rays received from the x-ray source while the subject is repeatedly positioned.
    Type: Grant
    Filed: June 3, 2009
    Date of Patent: April 26, 2011
    Assignee: General Electric Company
    Inventors: Jiang Hsieh, Paul E. Licato, Akira Hagiwara, Mark Vincent Profio, Karen Ann Procknow, Saad Ahmed Sirohey, Srinivas Aluri, Olga Imas

  • Systems and methods for improving usability of images for medical applications
    Patent number: 7620444
    Abstract: A method for retrospective internal gating is provided. The method includes scanning a patient to obtain projection data, generating images from the projection data, generating a signal representing information regarding a physiological cycle of an object within the patient, specifying at least one target phase based on which the images can be sorted, and sorting the images based on the target phase within a cycle of motion of the object to generate at least one series of images.
