  • Method to reduce radiation dose in multidetector CT while maintaining image quality
    Patent number: 10058302
    Abstract: A method of reducing radiation dose for a selected organ on a patient in a computed tomography (CT) scan that uses an X-ray source to scan the patient. The method comprises a computer determining a tube start angle for the X-ray source of the CT scan based on a location of the selected organ, a starting location of the X-ray source, a beam width of the CT scan, and a pitch of the CT scan. The starting angle of the X-ray source of the CT scan can then be set based on the determined tube start angle. In some embodiments, the organ location, X-ray starting location, beam width, and pitch are used to determine the number of tube rotations from the X-ray starting location to the organ location. This tube rotation number can be used to determine the tube start angle.
