Abstract:
A method for generating an image of an object using data collected in a computed tomography imaging system, said system comprising an x-ray source, an x-ray detector aligned with said x-ray source, and a display for displaying image reconstructed from data collected by said detector, said method comprising the steps of:determining a defined condition of the object;scanning the object with the computed tomography imaging system to obtain projection data of the object;selecting a portion of the projection data obtained while the object is in the defined condition;weighting projection data in accordance with a halfscan weighting function; andgenerating image data for the defined condition from the weighted data, andwherein selecting a portion of the projection data obtained while the object is in the defined condition comprises the steps of:determining an end of data point;determining a minimum data duration; anddetermining a begin data point utilizing the determined end of data point and the determined minimum data duration.
