Local affine transformation method for tomosynthesis

Abstract

In this report, a new method for image reconstruction for tomosynthesis is proposed. This technique consists in using local affine transformations and preliminary geometric calibration. The suggested approach makes it possible not to consider the geometry of the instrument and possible inaccuracies in determining the parameters of the investigation. As a result, this method allows achieving a higher tomography resolution. A comparison was made with the methods that are currently used in tomosynthesis. Experiments based on the results of real mammography researches were conducted.
