High resolution stationary digital breast tomosynthesis using distributed carbon nanotube x‐ray source array
Abstract
The purpose of this study is to investigate the feasibility of increasing the system spatial resolution and scanning speed of Hologic Selenia Dimensions digital breast tomosynthesis (DBT) scanner by replacing the rotating mammography x‐ray tube with a specially designed carbon nanotube (CNT) x‐ray source array, which generates all the projection images needed for tomosynthesis reconstruction by electronically activating individual x‐ray sources without any mechanical motion. The stationary digital breast tomosynthesis (s‐DBT) design aims to (i) increase the system spatial resolution by eliminating image blurring due to x‐ray tube motion and (ii) reduce the scanning time. Low spatial resolution and long scanning time are the two main technical limitations of current DBT technology.
