Methods and apparatus for two-pass CT imaging |
摘要 |
One aspect of the present invention is a method for imaging a volume of a patient with a computed tomographic (CT) imaging system. The method includes steps of: scanning a volume of a patient with a first, full field of view (FOV) scan to acquire first projection data; scanning a smaller volume of the patient with a second, restricted FOV scan to acquire second projection data; estimating an amount of shift between the first projection data and the second projection data resulting from patient movement; and blending first projection data with second projection data in accordance with the estimated amount of shift to estimate projections of the second scan.
