  • Patent number: 9532750
    Abstract: Contrast from dual energy CT images is removed without affecting other aspects of the image, including objects surrounded by contrast. Dual energy images are acquired during a study of a subject. First, a binary mask image (“Contrast localizer”) is produced to localize the contrast-enhanced areas and build sets of images with contrast-enhanced areas only (“Contrast images”) and complement images with contrast-enhanced areas removed (“Contrast complement images”) for both low and high x-ray beam energy image sets. Only the contrast images are used for dual energy contrast subtraction. Second binary mask image (“Subject localizer”) is produced to localize the objects under study. This mask image is used to reconstruct both low and high energy image sets with contrast selectively removed and subject present.

  • Publication number: 20100128945
    Abstract: A method for temporally imaging a cyclic body structure during a predetermined phase of its cycle using a CT scanner of the type having a rotating radiation source. In one embodiment the image or other display is generated using data produced when the radiation source is at a predetermined position when the body structure is in the predetermined phase. The method can be performed by using only data collected when the radiation source is at the predetermined position and the body structure is in the predetermined phase, by stimulating the body structure so the phase of the body structure and location of the radiation source are synchronized, or by controlling the motion of the radiation source so the location of the radiation source and the phase of the body structure are synchronized.
