Abstract
This research is aimed at studying the advantages of an x-ray phase-contrast tomosynthesis prototype by using phantoms. A prototype system is assembled with a micro-focus x-ray source, a rotating stage and a computed radiography detector mounted on an optical rail. A custom designed bubble wrap phantom is used in experiments. Angular projection images are acquired from -20° to +20° with 2° interval. The in-plane slices are reconstructed. The feature area on the phantom is observed. The prototype system provides an intrinsic way to investigate the potential and imaging quality of a phase-contrast tomosynthesis imaging method. As the result, phase-contrast tomosynthesis imaging method is demonstrated for its advantages in avoiding structure noise and overlapping issues by comparing the results acquired by computed radiography and phase-contrast radiography.
