Because you can detect more in 3D.
Tomosynthesis provides a high level of sensitivity and specificity, based on the development of flat-panel detectors and advanced digital-image processing techniques.

 

Digital Breast Tomosynthesis has already been adopted in clinical routine for the diagnosis of abnormal screening mammograms or clinical symptoms. Studies have proven its diagnostic efficiency, and it shows high potential to become a routine screening setting in the near future.

With True Breast Tomosynthesis, Siemens delivers a highly reliable diagnostic tool. The innovative technology leverages the largest angle with the highest number of projections for enhanced visualization. A total of 25 projections, acquired in an overall angle of 50°, allow for significantly improved diagnostic capabilities.

 

For clear results and a confident diagnosis.

Going 3D
Although the technology is currently the state-of-the-art, mammography suffers from decreasing sensitivity as tissue density increases. This can result in unclear images, which in turn can lead to cancers being missed, especially in patients with dense breasts.
Mammograms also present certain challenges in image reading and interpretation. A 3D object like the breast displayed as a 2D X-ray image forcibly leads to a loss of image depth information. Due to image superimposition, lesions may be masked by the tissue above or underneath, or normal structures may mimic a lesion. True Breast Tomosynthesis helps reduce these challenges.
 

How tomosynthesis works
With tomosynthesis, a full-field digital mammography system acquires multiple projection images of the breast. The X-ray tube moves through an isocentric arc above the stationary detector. It acquires several images of the breast in various angles. The projection images are then reconstructed into a 3D volume in DICOM format for flexible display on reading and reporting workstations. Reviewing physicians can scroll through the slices for a comprehensive overview. The 3D image quality and depth resolution directly depend on the number of projections, angle size as well as the reconstruction algorithm.
 

True Breast Tomosynthesis
Imaging has always been a core competence at Siemens. Challenging our innovation leadership and interdisciplinary know-how, we have evolved the current diagnostic approach for breast cancer to a new level. Our solution, derived from Siemens CT technology, allows both physicians and patients to feel confident. It can reduce unnecessary recalls and improves the early stage detection rate.
 

With True Breast Tomosynthesis, Siemens has opened up a new chapter in mammography diagnostics. High spatial resolution and the largest acquisition angle allow for excellent resolution depth and superior reconstruction results. This leads to fewer artefacts and greater image detail, thereby improving diagnostic capabilities immensely.

 

The number of projection images and the angular range of the tomosynthesis system directly affect the quality of the resulting 3D image. Optimizing both criteria, Siemens offers physicians an excellent diagnostic basis. The innovative system acquires an image every two degrees while moving through an angular range of 50°. This results in 25 projections for 3D reconstruction that allow for outstanding image quality.

 

Be confident. Be precise. Be sure.
