To describe the acquisition techniques of digital tomosynthesis (DT) To demonstrate various DT applications by presenting clinical images To illustrate both the clinical advantages and limitations of DT 

Acquisition techniques DT radiography/fluoroscopy/digital breast tomosynthesis (DBT) FBP/iterative reconstruction (IR) Clinical applications head and neck: sinonasal/dental disease chest: pulmonary nodule orthopedic: fracture detection/postoperative follow-up, particularly with metallic implant (metallic artifact reduction by segmentation or IR)/spine disease/joint space assessment fluoroscopy: IVU/upper GI/Ba enema DBT: breast cancer (artifact and radiation dose reduction by IR) Clinical advantages & pitfalls improved anatomical visualization/diagnostic accuracy (vs. non-DT radiography/fluoroscopy) artifacts: blurring/ripple/ghosting less dose/metallic artifact/dependency on patients’ posture (vs. CT) improved workflow/cost-effectiveness (vs. CT)
