Abstract

A system (SYS) and related method for motion artifact reduction in X-ray imaging. The system (SYS) comprises an input interface (IN) for receiving a first input image (i1, I1) of an object (PAT) reconstructed from a first set of projection data, and a second input image (i2, I2) of the object reconstructed from a second set of projection data. The second set is smaller than the first set. A motion analyzer (MA) establishes an estimate for motion corruption based on the two input images. A selective combiner (Σ) computes an image value for an enhanced image (I1+I2, i1+i2), based on the motion estimate and on image information in the first input image (i1, I1) and/or the second input image (i2, I2).
