AB - Digital breast tomosynthesis (DBT) provides a pseudo-3Dreconstruction which addresses the limitation of superimposition of densefibro-glandular tissue associated with conventional mammography. Reg-istration of temporal DBT volumes searches for the optimum deforma-tion to transform two observed images of the same object into a commonreference frame. This aligns the two images via minimising an objectivefunction that calculates the similarity between the two datasets.In this paper, we present a novel algorithm which combines recon-struction of a pair of temporal DBT acquisitions with their simultaneousregistration. We approach this nonlinear inverse problem using a genericunconstrained optimisation scheme. To evaluate the performance of ourmethod we use 2D and 3D software phantoms and demonstrate that thissimultaneous approach has comparable results to performing these taskssequentially or iteratively w.r.t both the reconstruction fidelity and theregistration accuracy.
