Abstract

The geometric accuracy of a digital breast tomosynthesis (DBT) reconstruction algorithm was assessed using an anthropomorphic software breast phantom with simulated fiducial markers. The locations of the fiducial markers were measured from supersampled images reconstructed to sub-pixel precision. The measured locations were compared with the known ground truth positions of the simulated markers. The fiducial markers simulate small, attenuating objects within the software phantom. Using reconstructed images with resolution of 0.115 mm, and a total of twelve fiducial markers at three different depths, we determined an average difference of 0.105 mm (st. dev. 0.086 mm) between the estimated and true marker locations.
