摘要
A method and system for computed tomography. Data is collected along a circular trajectory of an x-ray source. Data missing from the circular data is approximated. This may be accomplished by generating data that would have been collected along a line trajectory of the x-ray source. The image is reconstructed using the circle data and the approximated data. The circle views may be reconstructed from the circle data using a conventional Feldkamp reconstruction while the line data that would have been collected may be reconstructed as a correction to the Feldkamp reconstruction. The correction may be made by image addition, by adding the pixel values of the images reconstructed from the circle data and the approximated line data.
