ABSTRACT:
The invention relates to a device and a method for the iterative reconstruction of the attenuation coefficients μjin a tomographic image of an object (1) from projection measurements mi. In the update equation for μjnduring the n-th iteration the backprojected error (mi−mi−(μjn)) is weighted by a voxel dependent factor Formula (I). Such a voxel dependent update may particularly be included in the algorithms of ART or ML.
