  • Imaging methods and apparatus particularly useful for two and three-dimensional angiography
    Patent number: 6754522
    Abstract: A method and apparatus for angiographically imaging a portion of a patient's vascular system, by: (a) producing a first sequence of masking images of the portion of the patient's vascular system; (b) determining the masking image in the sequence having a minimum change over its immediately preceding masking image in the sequence; (c) injecting a contrast material into the patient's vascular system; (d) producing a corresponding sequence of contrast images of the portion of the patient's vascular system while containing the contrast material and (e) subtracting from each contrast image of the sequence the corresponding masking image in the sequence starting with the minimum change masking image, to thereby produce a difference image having an enhanced contrast-to-noise ratio (CNR).
