            Our Sun is a star. In fact, it is the closest star we'll ever see. The Sun is about 5 billion years old and will live for about 5 billion more. But not all stars live this long.

              Abstract: Digital tomosynthesis refers to a three-dimensional low-dose X-ray imaging technique that allows reconstruction of an arbitrary set of planes in the object from limited-angle series of projection images. In breast imaging fields, compared with standard mammography, digital breast tomosynthesis (DBT) improves conspicuity of structures by removing the visual clutter associated with overlying anatomy. In chest imaging fields, the technique has been commercially available. This talk focuses on image reconstruction algorithms and optimization for the digital breast tomosynthesis imaging technique to improve early breast cancer detection. Applications with pulmonary nodule detection and other potential clinical and industrial applications will also be discussed.

                    DEM L50 is what astronomers call a superbubble. These objects are found in regions where massive stars have formed, raced through their evolution, and exploded as supernovas.
