PRIMOR method combines image reconstruction and motion estimation in a single algorithm

We propose PRIMOR method that combines image reconstruction and motion estimation in a single algorithm. It extends previous prior-based reconstruction methods by including a model of the motion between consecutive frames into the cost functional. The resulting optimization problem is efficiently solved with the split Bregman formulation. Motion is estimated using a nonrigid registration method based on hierarchical B-splines.
In this paper we compare PRIMOR with a prior-based reconstruction algorithm for respiratory gated CT, resulting in a significant reduction of artefacts and improved image quality.
