Abstract
A method, apparatus, and computer readable medium for removing an unwanted object from an image volume are provided. Volumetric data of an object of study is generated in a radiographic scan. Volumetric data of the unwanted object is obtained. The two sets of volumetric data are registered in a common coordinate system. The unwanted object is removed from the volumetric data of the object of study to create modified volumetric data of the object of study. Data from voxels surrounding the removed unwanted object may be used to populate voxels corresponding to the unwanted object with interpolated data. A plurality of forward projections are performed on the modified volumetric data of the object of study, and a tomogram with the unwanted object removed is constructed.
