Abstract
Reconstructed 3D volumes from computed laminography data suffer from blurring artefacts due to the laminographic geometry. Such losses in quality can be compensated for by integrating a priori information about the test object into the iterative reconstruction process. However, this requires the position of the a priori model to be fitted exactly to the measured data. A (semi-)automatic 2D-3D registration algorithm which only requires a minimal additional user input and is based on a mathematical optimization problem is presented. Using measurement data obtained by simulating X-ray projections of the laminographic scanner CLARA the algorithm is validated.
