Two clinical images of the same breast side by side reveal the difference in image quality with two types of 3D mammography technology

50° Wide-Angle TomosynthesisSuperior by design.

With our 50° Wide-Angle Tomosynthesis, you benefit from a superior, highly accurate method of cancer detection that allows you to diagnose with confidence. This will result in excellent outcomes for breast care professionals, for radiologists, and – most important – for the many women and their families personally affected by breast cancer.

We at Siemens Healthineers know that with 50° you realize the full potential of tomosynthesis.

Put accuracy first

50° Wide-Angle Tomosynthesis is more accurate

While 2D mammography may leave as many as 30% of malignant tumors undetected,3 one of the largest studies worldwide with more than 15,000 screened patients has shown that 50° Wide-Angle Tomosynthesis provides an increased detection rate for invasive cancer of 43%, with just a 1-view tomosynthesis scan and a 15% dose reduction.1,4

With 50° Wide-Angle Tomosynthesis you can achieve the highest depth resolution

With 25 projections (the highest number available), our 50° Wide-Angle Tomosynthesis helps you gain deeper insights. Overcome diagnostic challenges like overlapping tissue with the highest mass detectability6 and a depth resolution that is 3.5 times higher than with a narrow angle,4 enabling you to see more and detect more.

How our 50° Wide-Angle Tomosynthesis works

With 50° Wide-Angle Tomosynthesis, you can achieve the highest depth resolution.8a

Depth resolution can vary based on the angular range

Depth resolution is important in 3D imaging, as a lesion can be masked by normal glandular breast tissue.

Wider angle can provide better lesion detectability

Discover how the higher depth resolution avoids an overlapping tissue effect that can mimic a lesion.

What do our clinical experts have to say?

Scientifically proven

Clinically validated, 50° Wide-Angle Tomosynthesis increases diagnostic certainty with highly defined tissue and lesion morphology in unprecedented detail. Get more clinical evidence:

Precision is key when taking a tissue sample. Biopsies guided by 50° Wide-Angle Tomosynthesis have a target accuracy of ± 1 mm. Less need for retargeting means less stress on the patient and makes life easier for your staff.

mammography tomosynthesis - biopsy

Faster and more accurate biopsies of virtually all kinds of lesions, thanks to: 

  • One-click targeting 
  • Intuitive guided workflows
  • Wide range of compatible biopsy devices 
  • Both vertical and lateral needle access 
  • Compatibility with a variety of needle sizes 
  • Motorized needle movement in X, Y, Z axes  
  • Spacer plate to ease targeting 
  • Integrated scanner InSpect immediately checks the specimen in 20 sec. right in the exam room

Sustain her loyalty

Designed for her – with personalized dose and compression

The success of screening programs largely depends on patient acceptance. We designed our tomosynthesis with a positive patient experience in mind. With our 50⁰ Wide-Angle Tomosynthesis, we enable superior cancer detection1 with the right dose and compression for every woman.

More and more studies are showing that a 1-view tomosynthesis exam is at least as accurate as the 2-view FFDM examination traditionally used in screenings.

The comparison of dose levels by different vendors shows the basically low dose exposure of our systems and the fact that a higher number of projections in tomosynthesis does not necessarily result in higher dose. Furthermore, this comparison shows that dose can be saved with 1-view tomo compared to 2-view FFDM.9,10

Drive efficient screening

You may be reluctant to go from 2D to 3D because tomosynthesis images give you a completely different kind and amount of information. With Insight 2D, the synthetic twin of FFDM, you get the image impression you are used to from years of FFDM reading, helping you with the transition from 2D to tomosynthesis.
