Two new features offer interventional guidance
Siemens adds two new features to its established Pure platform, which simplifies the adoption and utilization of advanced features on the Artis zee, Artis Q, and Artis Q.zen angiography systems. Designed to aid in endovascular aneurysm repair (Evar), syngo Evar Guidance offers automated detection of vessel walls on computed tomography (CT) datasets as well as automatic placement of landmarks for 3D image guidance. Additionally, it suggests the optimal angulation of C-arms for precise deployment. Enabling better treatment of highly challenging chronic total occlusions (CTOs), syngo CTO Guidance automatically segments coronary computed tomography angiography (CTA) images in addition to providing procedural guidance.

New tomosynthesis technologies are making image assessment more precise

In early detection of breast cancer, the accuracy of the radiological images determines how reliably a suspected tumor can be ruled out. Conventional mammography provides individual 2D images of the breast, so the tissue overlaps. With tomosynthesis, on the other hand, multiple images are taken from different angles and then displayed in slices, allowing the radiologist to "scroll" through them during the assessment. The individual slices reduce overlapping and thus facilitate a better diagnosis. High Definition Breast Tomosynthesis from Siemens Healthcare scans with a 50-degree angle which is the widest angle of all vendors and the largest number of individual images – 25 in all.

Using new technologies, Siemens Healthcare is now further developing the visualization of tomosynthesis scans. The new Empire technology11 (Enhanced Multiple Parameter Iterative Reconstruction) allows the slices to be reconstructed more precisely with the help of new algorithms. This makes the images sharper and enables microcalcification to be identified and defined more clearly as either benign or malignant, depending on the shape, reducing the need for biopsy. Often, a 2D mammography scan is prepared in addition to a tomosynthesis scan in order to obtain a better complete view of the breast. Insight 2D11, a software generated 2D visualization of tomosynthesis, can replace the mammography image and thus reduce X-radiation dose during breast exams. Insight from Siemens Healthcare is the first and only solution to offer 2D and well as 3D images11. The ability to view the tomosynthesis scans of the entire breast in 3D make it easier to identify the shape and distribution of microcalcifications and more complex tumors.
