Enhancing imaging capabilities with breast tomosynthesis

15.10.2009
Siemens releases first mammography systems equipped with 3D tomosynthesis

Siemens Healthcare has now integrated 3D tomosynthesis into its Mammomat Inspiration digital mammography platform. This technology compiles three-dimensional images of the breast and can therefore detect tumors even if hidden by overlapping tissue.


This enables a more accurate diagnosis than before and reduces the number of false positive findings. The first Mammomat systems with tomosynthesis have now been installed in Germany and in Belgium.

Dr. Renate Tewaag from Radprax - a group of practices specializing in radiology, nuclear medicine and radiation therapy - was the first radiologist in Germany to use this new Siemens technology.

"With tomosynthesis we are witnessing a fascinating further development in digital mammography. This 3D technology offers impressive improvements in the detection of detail, which benefit both patients and radiologists alike: We can be more certain in our diagnosis, while women being examined can feel more reassured", explained Dr. Tewaag. "Tomosynthesis makes mammography less stressful for both the physician and patient. Based on current first impressions, additional examinations and interventions can be avoided with a clear conscience. Lesions hidden within the dense glandular tissue are identified at an earlier stage."

So far, conventional analog mammography and digital full-field mammography was only able to display the three-dimensional anatomical structure of the breast on a two-dimensional level. This made diagnosis more difficult and limited the possibility of the physician identifying certain types of tumor; since, anatomical structures could overlap and obscure lesions. The 3D tomosynthesis technology in the Mammomat Inspiration overcomes these limitations: The technology acquires several projections of the breast from different angles using a fast detector based on amorphous Selenium (aSe) and uses this raw data to generate a 3D volume set. This enables a better analysis of the type and size of lesions as well as microcalcifications compared to conventional methods.

Tomosynthesis increases the sensitivity and specificity of mammography, as well as improving tumor differentiation and classification.

Tomosynthesis differs from conventional mammography in the same way that, for example, a CT scan (computer tomography) differs from a classical X-ray image. During the examination, the Xray tube moves in a 50-degree arc around the breast, taking 25 low-dose images. The images are then used as raw data to construct high-resolution 3D images. High spatial resolution and a wide acquisition angle result in the production of mammography images with unparalleled image quality.

The digital Mammomat Inspiration system with basic screening and diagnostic functions has been on the market since the end of 2007 and is widely used in hospitals and medical practices around the world. Mammomat Inspiration offers screening, diagnostics, stereotactic biopsy, and now tomosynthesis for the first time together on a single integrated digital platform. Any hospital or practice can purchase a screening device and add the biopsy and 3D tomosynthesis applications at a later time if necessary. Soon, all installed systems of this type can be upgraded on-site with the tomosynthesis function.

The Siemens Healthcare Sector is one of the world's largest suppliers to the healthcare industry and a trendsetter in medical imaging, laboratory diagnostics, medical information technology and hearing aids. Siemens is the only company to offer customers products and solutions for the entire range of patient care from a single source – from prevention and early detection to diagnosis, and on to treatment and aftercare. By optimizing clinical workflows for the most common diseases, Siemens also makes healthcare faster, better and more cost-effective. Siemens Healthcare employs some 49,000 employees worldwide and operates in over 130 countries. In fiscal year 2008 (to September 30), the Sector posted revenue of 11.2 billion euros and profit of 1.2 billion euros.

Im Focus: Scientists present new observations to understand the phase transition in quantum chromodynamics

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...

Im Focus: Patented nanostructure for solar cells: Rough optics, smooth surface

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.

"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...

Im Focus: New soft coral species discovered in Panama

A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.

Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
