AB - Digital Breast Tomosynthesis (DBT) offers potential insight into the fine details ofnormal fibroglandular tissues and abnormal lesions, e.g., masses and micro-calcificationsassociated with breast cancer, by the production of a pseudo-3D image. In addition, itavoids the superposition, which is usually found in X-ray mammography, with a compa-rable radiation dose. Algorithms to aid the human observer process DBT data sets involvetwo key tasks: reconstruction and registration. In established medical image modalitiesthese tasks are normally performed sequentially; the images are reconstructed and thenregistered. In this paper, we hypothesise that, for DBT in particular, combining the op-timisation processes of reconstruction and registration into a single algorithm will offersatisfactory for both tasks. Based on this hypothesis, we have devised a mathematicalframework to combine these two tasks, and have implemented both affine and non-linearB-spline registration transformation models as plug-ins. By applying our algorithm tovarious simulated data, we demonstrate the success of our method in terms of both re-construction fidelity and in the registration accuracy of the recovered transformations.
