Abstract
A method and apparatus for reducing artifacts in image data generated by a computed tomography system is provided. The artifacts are due to the presence of a high density object in a subject of interest. CT data is acquired at a number of differing tilt angles. The data is then combined and reconstructed to generate an improved composite image substantially free of artifacts caused by the high density object.
