WE‐D‐304A‐09: Characterization of Multi‐Beam Field Emission X‐Ray Source for Stationary Digital Breast Tomosynthesis

Purpose : The current prototype digital breast tomosynthesis (DBT) scanners are based on the regular full‐field digital mammography systems and require partial isocentric motion of a mammography x‐ray tube over certain angular range to record the projection views needed for reconstruction. This prolongs the scanning time and in turn degrades the imaging quality due to motion blur. We are developing a stationary DBT (s‐DBT) scanner to mitigate...
