Paper Abstract

We have recently developed a method of using a distributed x-ray source array to obtain images with scatter correction for tomographic reconstruction of an object. The method consists of obtaining x-ray images of the object with and without the primary beam sampling apparatus. In this study, we report the results of applying the scatter correction method for breast tomosynthesis imaging using the carbon nanotube x-ray based stationary Digital Breast Tomosynthesis (s-DBT) system developed at UNC. The unique design of s-DBT system makes it possible to estimate the image of the scatter profile of the object with very low dose, and without significant increase in acquisition time. An anthropomorphic breast phantom was used for quantitative analysis of the change in contrast and scatter-to-primary ratio. Our results suggest that the scatter correction method is effective and can be used for enhanced contrast.
