News syngo CT 2010B Now Available: New Software Version for the SOMATOM Defi nition AS Launched By Jan Freund, Business Unit CT, Siemens Healthcare, Forchheim, Germany The new syngo software version, CT 2010B, for SOMATOM Definition AS scanners, was released in April 2010. It makes IRIS (Iterative Reconstruction in Image Space) available to SOMATOM Definition AS customers. With IRIS, a dose reduction of up to 60% is possible without compromising image quality. In addition, native head-image quality can be significantly improved with Neuro BestContrast without an increase in dose. By separating low and high fre- Worldwide Dose Counter By Peter Seitz, Business Unit CT, Siemens Healthcare, Forchheim, Germany With the SOMATOM Definition Flash, coronary CTAs become routinely available at dose levels below 1 mSv. Now everybody can check dose values for themselves, in daily routine, worldwide, and in almost real-time. Being able to image the coronary arteries with a radiation dose of below 1 mSv is impressive in itself, but it becomes even more impressive when this happens everyday, all around the globe and not just in a few specialized cases. That’s why Siemens decided to make average doses of Flash Spiral Cardio scans – our all-new high-pitch mode for scan speeds up to 458 mm/s – publicly available. With this ultrafast scanning, the SOMATOM Definition Flash acquires the entire heart in only around 270 ms, reducing radiation exposure to the minimum, all the while maintaining the excellent image quality that previously was only possible at much higher dose levels. At www.siemens.com/low-dose anyone can observe the current average dose on the installed base. This value is updated every 30 minutes by statistical data 20 SOMATOM Sessions · May 2010 · www.siemens.com/healthcare-magazine quency data, it specificly optimizes the tissue contrast without amplifying the image noise, resulting in an improvement of signal to noise ratio of up to 30 %. In dynamic studies, such as CT Perfusion images, noise can be significantly reduced. As a result, radiation dose can be lowered without compromising image quality. The Adaptive Signal Boost optimizes lower signals, e.g. when low dose or obese protocols are used. Neuro BestContrast, 4D Noise Reduction and the Adaptive Signal Boost will be available free of charge. CARE Contrast II synchronizes CT scan and contrast media injection. With its open interface technology, it is ready for future applications. The syngo CT 2010B will be delivered with all new systems beginning in May 2010 and as a field roll-out to the complete installed base of the SOMATOM Definition AS.

syngo.via Workstation Face-off Sessions By Karin Barthel, Business Unit CT, Siemens Healthcare, Forchheim, Germany At RSNA 2009, Siemens Healthcare introduced their new imaging software, syngo.via,* a client-server based software solution which allows to display most used applications across various imaging modalities – dedicated not only to general radiology but tailored to specific clinical fields such as oncology, neurology, vascular imaging and cardiology as well. Since then, syngo.via has participated at 2 major face-offs. At a face-off, several industry vendors enter the arena to demonstrate cases live on their respective workplaces, permitting the audience to make an immediate, direct comparison of the software versions and results. First, syngo.via met the challenge at the 6th International MDCT Symposium 2010 in Garmisch-Partenkirchen, Germany, where about 1.600 CT experts were registered. Thomas Mang, MD, from the University Hospital in Vienna demonstrated the cases for Siemens. The first was a vascular case where an aneurysm needed to be evaluated. With syngo.via, Mang could fulfill all tasks ahead of time in outstanding clinical quality. Only 2 minutes were required since many steps, like table removal, bone removal, naming of vessels, curved MPRs and orthogonal views, were automatically calculated by syngo.CT Vascular Analysis.** The second case was an oncology case in which multiple liver lesions had to be measured. The automatic synchronization of datasets, the propagation of previous results and the unique Findings Navigator helped to speed up the workflow tremendously. The contouring algorithm worked perfectly and measured reliably, even for the very complex liver lesions that, in comparison to the surrounding tissue, showed very similar density. The second competition was the workstation face-off at the ECR in March 2010 in Vienna, Austria. There, 3 cases where demonstrated by Marco Das, MD, from the University Hospital in Maastricht, The Netherlands. The first case was a vascular case whereby a high-grade stenosis in the common carotid artery needed to be quantified and an occlusion in the MCA segment had to be displayed. The case was completed with syngo.via with only a few steps. Due to all the automated tools, Das only had to click into the areas of interest and could show the results. The second case was a brain perfusion in which the MTT, CBF and CBV parameters had to be measured. Here it was only necessary to open the syngo Volume Perfusion CT Neuro application to accept the results and to place a ROI into the infarction. Everything else was automatically calculated by the system. All in all, this took only 45 seconds. The third case was a PET/CT case in which the assessment of response to treatment between 3 time-points had to be done with an volumetric assessment according to RECIST, WHO and volume, including percentual change between examinations as well as an metabolic SUV assessment based on PET data. With the Findings Navigator it was very simple to jump from finding to finding. And the comparison of findings was easy to use since all images such as CT, PET, Fused and MIP images were displayed next to each other. Due to the dedicated lung, liver and lymph algorithms, all kinds of lesions, no matter if large or small were contoured and measured precisely. These results showed that syngo.via currently will be an industry standard for state-ofthe-art imaging solution. News With syngo.via, a vascular case, demonstrated during the face-off in Vienna, was completed with only a few steps due to automated tools. Thomas Mang, MD, AKH, Vienna, Austria “Due to the automated features within syngo.via, manual preparation of cases is no longer necessary. Now, a radiologist can start working where he wants to start, with reading the case.” Marco Das, MD, Maastricht University Medical Center, The Netherlands “I saw the syngo.via face-off in Garmisch and was very impressed. So, when I was asked to demonstrate it in Vienna, I agreed immediately. Although the software was new for me, it was easy to learn and I was proud to demonstrate it at the ECR.” * syngo.via can be used as a standalone device or together with a variety of syngo.via based software options, which are medical devices in their own rights. ** The information about this product is being provided for planning purposes. The product is pending 510 (k) review, and is not yet commercially available in the U.S.
