Digital Tomosynthesis (DTS) a new advanced breast cancer imaging technique

Digital tomosynthesis, is a method for performing high-resolution limitedangle tomography at radiographic dose levels. Digital tomosynthesis (pronounced toh-moh-SIN-thah-sis) creates a 3-dimensional picture of the breast using X-rays. It takes multiple X-ray pictures of each breast from many angles. The breast is positioned the same way it is in a conventional mammogram, but only a little pressure is applied — just enough to keep the breast in a stable position during the procedure. The X-ray tube movesin an arc around the breast while 11 images are taken during a 7-second examination. Then the information is sent to a computer, where it is assembled to produce clear, highly focused 3-dimensional images throughout the breast. Early results with digital tomosynthesis are promising. Researchers believe that this new breast imaging technique will make breast cancers easier to see in dense breast tissue and will make breast screening more comfortable. In this approach we review detail of this technique in breast cancer imaging.
