      abstract = {An apparatus and method are provided for computed  tomography (CT) imaging to reduce artifacts due to objects  outside the field of view (FOV) of a reconstructed image.  The artifacts are suppressed by using an iterative  reconstruction method to minimize a cost function that  includes a de-emphasis operator. The de-emphasis operator  operates in the data domain, and minimizes the  contributions of data inconsistencies arising from  attenuation due to objects outside the FOV. This can be  achieved by penalizing images that manifest indicia of  artifacts due to outside objects especially those outside  objects have high-attenuation densities and minimizing  components of the data inconsistency likely attributable to  the outside object.},
