It is a revolutionary technology that combines the advantages of digital mammography with a 3D image of the breasts. 3D tomosynthesis creates multiple images or "slices" of the breast tissue which allows our radiologists to see greater detail and helps reduce the impact of overlapping Tomosynthesis uses x-rays to image the breast, and rotates around the breast while taking multiple images. Those images are then assembled to produce a highly focused 3D image.

The irregular mass due to invasive ductal carcinoma (in the area of the red ovals), is much better seen on the tomosynthesis(3D) slices than the 2D digital images. Breast tomosynthesis, also called three-dimensional (3-D) mammography and digital breast tomosynthesis (DBT), is an advanced form of breast imaging, or mammography, that uses a low-dose x-ray system and computer reconstructions to create three-dimensional images of the breasts. Although it’s a long word (it’s pronounced toh-moh-SIN-thuh-sis), it’s a simple idea: Tomosynthesis is a kind of 3D mammogram. It uses 3-dimensional imaging used to look for breast cancers.

23 Jun 2016 Digital tomosynthesis is a new kind of test that's trying to overcome these three big issues. It takes multiple X-ray pictures of each breast from

The 3D tomosynthesis acquisition parameters were the following: an overall angle of 50°, with the X-ray tube rotating 25° in both directions from the target by 2-degree increments to obtain 26 projection views. Tomosynthesis images obtained in the plane of a metallic clip, calcified oil cyst, and calcified vessel are sharply in focus (A, D, G). As one scrolls out of the plane of these structures, these objects initially become blurred (B, E, H) and then appear as zipper artifacts (C, F, I) as one moves even farther out-of-plane.

Thus, a display system preferably should be able to display both Mp and Tr (and/or Tp) images concurrently or sequentially.

Digital breast tomosynthesis (DBT) is an imaging technique that allows a volumetric reconstruction of the whole breast from a finite number of low-dose two-dimensional projections obtained by different X-ray tube angles, with a geometric principle very similar to that applied in stratigraphic technique.

There was a mean increase of 1.8 true positives for every 1.3 false positive Tomosynthesis at a glance. The term ”tomosynthesis” merges ‘tomography’ and ‘synthesis’. It is a special type of imaging technology that fuses cone-beam CT reconstruction with digital image processing to produce images of specified cross-sections from a single tomography. Universal tomosynthesis is based on the assumption that projected images will be acquired using an FPD for general radiography.
