Stationary Digital Tomosynthesis System for Early Detection of Breast Tumors
Abstract
Using a proof-of-concept bench-top set-up we recently demonstrated the feasibility of stationary digital breast tomosynthesis (s-DBT) utilizing a carbon nanotube (CNT) based distributed x-ray source array. The device generates the projection views by electronically activating the multiple x-ray beams. The approach has the potential to provide a fast scanning speed without sacrificing the spatial resolution by eliminating any motion blurring from the tube motion. The purpose of this study is to evaluate the feasibility of improving the spatial resolution and increasing the scanning speed by replacing the conventional scanning mammography tube with a stationary x-ray source array. We have successfully evaluated the features of CNT based distributed x-ray source array for improving the spatial resolution and increasing the scanning speed of the conventional DBT scanner.
