Abstract

Our prototype next-generation tomosynthesis (NGT) system is a tool for investigating novel acquisition geometries in digital breast tomosynthesis (DBT). One such geometry is a non-isocentric acquisition in which the detector descends in the superior-to-inferior direction during the scan. The advantage of this geometry is examined through analysis of super-resolution (SR) with a high-frequency test pattern. In clinical DBT reconstructions, SR is only achieved if the test frequency is oriented parallel with the direction of source motion. In the non-isocentric geometry, SR can be achieved isotropically; that is, for all orientations of the test pattern.
