What is tomosynthesis, and how does it work?

Tomosynthesis is an x-ray-based imaging technique that is used to create high-resolution tomographic (cross-sectional) images of a region of interest in the body. It works by first acquiring multiple x-ray images of a patient from various angles with a digital flat panel detector and then using computer algorithms to reconstruct the data into tomographic images.

What are some clinical applications of tomosynthesis?

Tomosynthesis can be used to potentially improve the detection of breast cancer (particularly in women with dense breast tissue) compared to mammography and to improve the detection of small lung nodules in the chest compared to chest radiography.
