SOMATOM Definition Edge The Reference in Single Source CT SOMATOM Definition Edge The Reference in Single Source CT For decades, Siemens has been the undisputed innovation leader in highend CT imaging. However, the clinical need to continuously improve image quality persists. Therefore, Siemens designed the SOMATOM Definition Edge with the revolutionary Stellar Detector – the first fully integrated detector that significantly reduces electronic noise. This takes CT imaging where it has never gone before. The uniqueness of the Stellar Detector allows the SOMATOM Definition Edge to generate ultra-thin slices, thus further improving spatial resolution in CT. It can visualize even finest image details and thus significantly enhances, for example, calcified plaque and stent analysis. It lets you see what was previously unseen. The combination of the reduced noise level of the Stellar Detector and SAFIRE*, Siemens’ raw-data-based interactive reconstruction, is the perfect match for ultra-low dose imaging. Together, they eliminate the contradiction between outstanding image quality and low dose. Physicians get more diagnostic quality at less patient radiation. Finally, Dual Energy becomes truly suitable for single source CT imaging. With the novel capabilities of the Stellar Detector and the only doseoptimized single source DE scan mode, the SOMATOM Definition Edge makes it possible to add tissue characteristics to morphology. With this, formerly unspecific morphology can now be specified for a higher level of diagnostic information. With these unrivaled features, the SOMATOM Definition Edge enters new frontiers in medical imaging and becomes The Reference in Single Source CT. 4 *In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.

Unprecedented spatial resolution The SOMATOM Definition Edge is equipped with the Stellar Detector and the STRATON® tube with z-Sharp™ Technology. This combination is the key to increasing spatial resolution. Using a flying focal spot with two distinct X-ray beams, z-Sharp acquires two individual, overlapping slices. The Stellar Detector delivers slices with a thickness of 0.5 mm, resulting in a routine spatial resolution of up to 0.30 mm, which is equivalent to approximately 18.2 lp/cm. 8 Uncompromised temporal resolution The new SOMATOM Definition Edge gantry has a rotation speed of 0.28 s. Combining this speed with the Stellar Detector and the STRATON tube, the scanner is able to achieve an outstanding temporal resolution of 142 ms. This makes it for ideal imaging with significantly reduced artifacts. At the same time, it can utilize the spatial resolution of up to 0.30 mm within the entire FoV of up to 500 mm. This is performance dedicated to outstanding clinical imaging. The STRATON tube and the newly designed gantry enable high spatial resolution even at an acquisition speed of up to 230 mm/s. This takes motion out of the equation. The Stellar Detector puts the SOMATOM Definition Edge in a class of its own with a routine spatial resolution of up to 0.30 mm, allowing visualizations of very fine structures or lesions. Unparalleled acquisition speed High acquisition speed with high spatial resolution is essential in acute care scenarios because providing diagnosis within the ‘golden hour’ mandates the precise localization and identification of critical injuries. The challenge for CT is to reduce motion artifacts when unconscious or uncooperative patients have to be scanned quickly. SOMATOM Definition Edge rises to the challenge with an acquisition speed of up to 230 mm/s at a spatial resolution of 0.30 mm. High-pitch high-resolution CT Increasing spatial resolution beyond the actual width of a detector row requires overlapping slices. For conventional CT systems, this means reducing pitch to facilitate the slice overlap. For scans requiring high pitch, the missing overlap then reduces spatial resolution. With z-Sharp, however, the overlap is achieved by acquiring two distinct projections. Consequently, the two slices overlap independently of the used pitch and can always provide highest resolution. 9 Get More from Less The SOMATOM Definition Edge is the reference in low signal imaging with optimized dose efficiency – essential for bariatric examinations or iterative reconstruction. Optimized low-signal imaging There are various reasons for scanning with low signals. For example, bariatric patients can cause strong attenuation. Reducing dose can also cause low signals. Many recent innovations, especially iterative reconstruction solutions, reflect this. It is therefore a logical step to introduce a detector that is specially optimized for low-signal imaging: the Stellar Detector with TrueSignal Technology. 10 Optimized bariatric imaging In a growing number of countries, a large portion of the population is considered obese. The SOMATOM Definition Edge answers the challenge of bariatric imaging with a 78 cm gantry bore and a table load capacity of more than 307 kg. And, of course, there is the outstanding image quality delivered by the new Stellar Detector with TrueSignal Technology. Radiation exposure [mSv] 9 Dose reduction in cardiac CT 8 7 6 5 4 3 2 1 0 Adaptive ECG Pulsing Optimized imaging at the right dose Iterative reconstruction allows significant improvements in image quality in terms of contrast and noise. It can be used to acquire data at lower dose and then maintain the image quality during the reconstruction. SAFIRE (Sinogram Affirmed Iterative Reconstruction) uses this approach to enable a dose reduction of up to 60%*. The unique low signal capabilities of the Stellar Detector optimize image quality, resulting in even higher sharpness and clarity despite the reduced dose. CARE kV CARE Dose4D MinDose Comprehensive dose protection In the mid-1990s, Siemens introduced its CARE philosophy following the ALARA (As Low As Reasonably Achievable) principle. The idea has been to utilize every means available to reduce patient exposure. Siemens is the only vendor to offer a dose protection portfolio that optimizes the scan according to all relevant parameters. From patient size to examination type, from mA to kV, and from scan preparation to data evaluation – everything is taken into consideration. Adaptive Dose Shield SAFIRE Stellar Detector Exemplary dose reduction in cardiac CT. Each application is designed to contribute to dose reduction during every step of the examination process resulting in an absolute minimum exposure. Optimized patient-centric imaging With CARE Dose4D™, Siemens offers a unique solution that actively modulates the tube current to the patient’s anatomy in real time. Additionally, CARE kV automatically suggests the appropriate kV (the selected voltage) to optimize the contrast-to-noise ratio of the image while limiting the applied dose. CARE kV takes both the patient’s body type and the examination type (non-contrast, bone, soft tissue, vascular) into consideration. *In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. The following test method was used to determine a 4 to 60% dose reduction when using the SAFIRE reconstruction software. Noise, CT numbers, homogeneity, low-contrast resolution and high contrast resolution were assessed in a Gammex 438 phantom. Low dose data reconstructed with SAFIRE showed the same image quality compared to full dose data based on this test. Data on file. 11 Specify the Unspecific Enhanced low kV image quality makes the SOMATOM Definition Edge the reference in functional imaging for Single Source Dual Energy examinations. Routine-ready Single Source Dual Energy Siemens’ pioneering application development has allowed CT to expand into new clinical fields. The introduction of Dual Energy (DE) imaging has added tissue characterization to morphology. Thanks to a combination of routine-ready scan modes and enhanced low-kV image quality at low dose, the SOMATOM Definition Edge brings these new applications to everyday clinical practice. 12 Calculi characterization* in clinical routine Many people in developed countries suffer from urinary stone disease. The imaging modality of choice for urinary stone disease is a low-dose, non-contrast CT scan. It is very easy to perform, does not require intravenous contrast and covers the entire abdomen and pelvis. The essential benefit in the diagnosis with Dual Energy CT is that the stone type can be identified. Functional imaging, e.g. with dual energy (image 1–3) or perfusion (image 4) , makes it possible to add tissue information to morphology Tissue characterization – Gout Gout is amongst the most common inflammatory joint diseases and many people in the western world are afflicted by this painful, destructive disease. With syngo.CT DE Gout*, a non-invasive assessment of gout is feasible. The algorithm color codes different attenuation values, so that the uric acid produced by the disease is directly verified, confirming the definite diagnosis of gout. Routine-ready metal artifact reduction Metal artifacts pose severe difficulties in CT imaging due to the resulting artifacts. Single Source Dual Energy now offers a solution. The unique Stellar Detector in the SOMATOM Definition Edge is specifically optimized to handle low kV signals with HiDynamics. And syngo.CT DE Monoener­ getic Imaging* enables the minimization of metal artifacts by specifically selecting keV levels at which the metal objects have least impact on image quality. Routine-ready dynamic imaging Stroke is one of the three most frequent causes of death worldwide. In the diagnosis and treatment of stroke cases, time is of the essence. With the Adaptive 4D Spiral, Siemens has introduced a scan mode that performs perfusion evaluations beyond the limitations of a static detector. In addition, the SOMATOM Definition Edge, with the Stellar Detector and HiDynamics, is the perfect choice for the acquisition of dynamic datasets, typically done at low kV levels. Perfusion information is crucial in many clinical fields such as stroke or tumor assessments. The Adaptive 4D Spiral is key to making these exams ready for clinical practice. *The product is pending 510(k) clearance and is not yet commercially available in the United States. 13 Added Benefits of syngo.via Regardless of volume or disease, syngo.via helps prepare cases, eases interdisciplinary collaboration, and helps generate a faster and more reliable diagnosis. syngo®.via for sustainable care As the number of chronic disease patients rises, the demand for high-quality, efficient care is increasing. syngo.via* is Siemens’ state-of-the-art imaging software, creating an exciting experience in efficiency and ease of use. syngo.via can help foster sustainable care by equipping physicians with workflows and applications for evaluating images from multiple modalities. In the case of cardiovascular CT, it enables a rule-out of coronary artery disease in less than a minute. 14 Automated syngo.via helps the physician to analyze the individual case, prepares images, suggests an opti-mized workflow, and offers guidance when needed. For example, when a cardiac case is opened, the Automated Case Preparation has already pre-processed the images and displays them in the appropriate layout together with adequate evaluation tools. Evaluation of the coronary vessels, the functional parameters, and the prepared calcium score can start immediately. Image networking syngo.via speeds up the way users connect and share information with clinical partners and patients – even on the go.** syngo.via’s client-server based nature supports a smooth, teamwork-like sharing of tasks, just as it is required in 3D labs and larger radiology departments. Images can be shared among multiple users at once, providing a sound basis for joint pre-procedural planning. As soon as the case is opened, it is ready for review – allowing, for instance, a quick assessment of an aortic dissection. Fast decisions in acute care CT is the modality of choice when it comes to diagnostic imaging in acute care situations – whether it is for a triple rule-out of acute chest pain, stroke assessment, poly-trauma, or acute abdominal pain. The CT Acute Care Engine provides clinical functionality that delivers decisive results for all of these challenging indications. Thanks to automatic pre-processing, the case is ready for reading as soon as it is opened. When every second counts The software within the CT Acute Care Engine isolates the heart, provides the angiography-like display, and also applies the radiologist’s preferred reading layout. For the assessment of intra- and extracranial vasculature, the CT Acute Care Engine provides fully automatic preprocessing of data, including automatic bone removal. Above all, speed and dependability add confidence for critical decisions made against the clock. Zero-click vessel assessment The CT Acute Care Engine facilitates assessment of the aorta and general vessels by providing a vessel-only view when the case is opened. The combination with the automatic side-by-side layouts, e.g. for displaying both carotid arteries, helps to better assess and evaluate complex lesions. In addition, the CT Cardio-Vascular Engine, CT Neuro Engine, and CT Oncology Engine offer an impressive range of advanced applications tailored to many clinical needs. * syngo.via can be used as a standalone device or together with a variety of syngo.via-based software options which are medical devices on their own rights. These products are pending regulatory clearance in some countries and therefore not yet commercially available in all countries. Usage of syngo.via in operating room or for an emergency case requires customer to provide respective emergency measures in case of non-availability of system or network. ** Prerequisites include: Internet connection to clinical network, DICOM compliance, meeting of minimum hardware requirements, and adherence to local data security regulations. 15 Clinical Images collimation: 128 x 0.6 mm scan time: 5s scan length: 156 mm rotation time: 0.28 s tube settings: 80 kV, 129 eff. mAs heart rate: 59–104 bpm CTDIvol: 8.55 mGy DLP: 149 mGy cm eff. dose: 2.08 mSv Myocardial bridge in the LAD – higher temporal and spatial resolution resulting in excellent image quality at lower dose; even with arrhythmia at 59–104 bpm LMU Grosshadern, Munich, Germany 18 collimation: 128 x 0.6 mm scan time: 2.8 s scan length: 654 mm rotation time: 0.28 s tube settings: 100 kV, 67 eff. mAs CTDIvol: 2.65 mGy DLP: 185 mGy cm eff. dose: 2.68 mSv TAVI planning – fastest single source acquisition speed at 23 cm/s allows for visualizing the whole range with exceptional image quality in TAVI planning LMU Grosshadern, Munich, Germany 19 collimation: 128 x 0.6 mm scan time: 2.6 s scan length: 593 mm rotation time: 0.28 s tube settings: 100 kV, 55 eff. mAs CTDIvol: 2.17 mGy DLP: 138 mGy cm eff. dose: 1.93 mSv Aortic dissection – faster acquisition speed allows for less breath-hold time in an acute care scenario LMU Grosshadern, Munich, Germany 20 collimation: 128 x 0.6 mm scan time: 4s scan length: 361 mm rotation time: 0.28 s tube settings: 100 kV, 72 eff. mAs CTDIvol: 2.85 mGy DLP: 93 mGy cm eff. dose: 1.3 mSv Interstitial lung disease – higher spatial resolution showing very detailed structure of the parenchyma of the lungs New York University Med Center, New York, USA 21 collimation: 128 x 0.6 mm scan time: 6s scan length: 416 mm rotation time: 0.5 s tube settings: 80 kV, 205 eff. mAs CTDIvol: 3.81 mGy DLP: 171 mGy cm eff. dose: 2.57 mSv Aortic ectasia – showing the vascular details and calcified plaques even in the 4th segment level Inselspital Bern, Bern, Switzerland 22 collimation: 128 x 0.6 mm scan time: 5s scan length: 225 mm rotation time: 0.5 s tube settings: 100 kV, 266 / 262 / 185 eff. mAs CTDIvol: 10.5 / 10.35 / 7.33 mGy DLP: 248 / 252 / 335 mGy cm eff. dose: 3.72 / 3.78 / 5.03 mSv Three phases liver – excellent low-contrast resolution for liver tumor visualization with great details of the vascular structures and differentiation of the soft tissues LMU Grosshadern, Munich, Germany 23 collimation: 128 x 0.6 mm scan time: 39 s scan length: 1221 mm rotation time: 1.0 s tube settings: 80 kV, 191 mAs CTDIvol: 3.55 mGy DLP: 446 mGy cm eff. dose: 2.5 mSv Angio run off – faster speed enables long range acquisition in a short time with great vascular details Clinique CIMOP Bizet, Paris, France 24 collimation: 128 x 0.6 mm scan time: 6s scan length: 146 mm rotation time: 1.0 s tube settings: 100 kV, 336 eff. mAs CTDIvol: 29.38 mGy DLP: 473 mGy cm eff. dose: 1.89 mSv Mastoiditis of the left ear – higher spatial resolution reveals greater details of the inner ear Inselspital Bern, Bern, Switzerland 25 collimation: 128 x 0.6 mm scan time: 6s scan length: 148 mm rotation time: 1.0 s tube settings: 120 kV, 290 eff. mAs CTDIvol: 41.84 mGy DLP: 677 mGy cm eff. dose: 1.42 mSv Leukoencephalopathy – great low contrast resolution allows for clear demonstration of multifocal white matter lucencies in the brain.

Thinner slices Thinner slices deliver more image detail, but also less light quants per voxel, i.e. higher image noise. This lowers the signalto-noise ratio. In addition, electronic noise causes cross-talk, which leads to slice blurring. Conventional CT compensates this by increasing dose. Thus, the further reduction of slice thickness was limited. Until now. 32 The Stellar Detector The Stellar Detector introduces the next generation in detector technology, succeeding gas and solid-state technology. Using nano-technology, it is possible to miniaturize the electronic components on the detector elements. For the first time, it is therefore possible to fully integrate the detector directly into the photodiode. This full electronic integration is Siemens' revolutionary TrueSignal Technology. Innovation delivers outstanding results High spatial resolution and high signal-tonoise ratio (SNR) are reliable indicators of excellent image quality. Together they describe the image detail level and sharpness that can be made visible while acquiring diagnostic CT images. In addition, the Stellar Detector provides a homogeneous slice profile with the same spatial resolution and SNR in the entire Field of View (FoV), which is essential for consistently high image quality. focal spot Conventional Technology Cross-talk resulting from slice blurring in a conventional detector. Edge Technology minimizes noise Full electronic integration of the detector elements minimizes electronic noise and cross-talk. Without cross-talk, slice blurring between neighboring detector rows can be significantly reduced, thus making the individual slice profile much more precise. Siemens’ Edge Technology creates an almost perfect model of the focal spot and detector, generating a slice thickness of 0.5 mm. With the minimized electronic noise, 0.5 mm constitutes not only a high-res mode but a standard mode. detector projection Edge Technology Minimized cross-talk from the Stellar Detector creates an almost perfect model of the focal spot. The result is a slice thickness of 0.5 mm. Higher signal-to-noise ratio Normally, the reduced light quants of a 0.5 mm slice would need compensation. The TrueSignal Technology of the Stellar Detector has a new answer to this challenge: instead of increasing dose, it makes more efficient use of the initially available quants per voxel. As the electronic noise of the detector is minimized, the overall noise is reduced, so that the quants contribute to a higher SNR. Scan to learn more about the new Stellar Detector. www.siemens.com/edge-stellar 33 TrueSignal Technology TrueSignal Technology optimizes dose efficiency and delivers outstanding image quality at reduced signal level. TrueSignal Technology raises SNR Based on the full electronic integration of the Stellar Detector, TrueSignal Technology significantly reduces electronic noise. The resulting SNR is improved for better utilization of low signals. Low-signal datasets benefit from increased sharpness and clarity, as the detector can now differentiate much better between the signal of individual voxels and the surrounding image data. 34 Comparable noise level at lower signal At high signal levels, the noise produced by the Stellar Detector with TrueSignal Technology is more or less the same as the one produced by conventional CT technology. However, when the signal is lowered – either by high attenuations from obese or broad shouldered patients, or by reducing the applied mA – the impact of TrueSignal Technology increases. Effective use of low signals Conventional detectors have a comparatively high intrinsic noise level that impairs image quality. The electronic integration of the Stellar Detector and TrueSignal Technology lowers the noise level significantly, so that the available signal can be processed more efficiently. This means that when there is high attenuation from very large patients, the detector can make better use of the measured low signal. SOMATOM Definition Edge 40 cm 40 cm fit noise [HU] 400 Conventional CT 40 cm 40 cm fit 300 -25% at 200 mA -20% 200 at 300 mA -12% at 400 mA 100 0 0 Iterative reconstruction When using iterative reconstruction methods, the CT images are retransferred to raw data after the initial reconstruction. Comparing this new synthetic raw data with the acquired data makes it possible to identify differences. An updated image is then reconstructed with reduced image noise but without noticeable loss of sharpness. This is repeated several times, reducing image noise incrementally and correcting geometrical imperfections. 50 100 150 200 250 300 350 400 450 500 current [mA] Reduction in mAs at the same noise level with the Stellar detector SAFIRE in clinical routine Iterative reconstruction allows to reduce mA, thus lowering the signal at the detector. Consequently, SAFIRE examinations benefit from the low-signal advantages of the Stellar Detector and TrueSignal Technol­ ogy. Combined with the high computational power of Siemens’ FAST image reconstruction system (IRS), they enable the use of SAFIRE in crucial clinical routine scenarios such as acute care. The result is more benefits for a larger number of patients. 35 HiDynamics The HiDynamics scan mode delivers an extended dynamic range for enhanced image quality in low kV scans and functional CT examinations. 36 1st scan 80 kV 2nd scan 140 kV Full dynamic range for more sensitivity Thanks to full electronic integration, the Stellar Detector now benefits from an extended dynamic range instead of having to switch bandwidth like conventional detectors. This unique feature is called HiDynamics. It increases the sensitivity of the detector for visualizing finer structures, especially for low kV datasets. Comparison of the 80 kV Dual Energy data set (left) with the 140 kV Dual Energy data set (right) shows: almost identical image detail level in 80 kV due to the improvement resulting from HiDynamics. Adding functional information HiDynamics and TrueSignal Technology thus have clear benefits in functional imaging applications such as Dual Energy. After acquiring two consecutive scans at different kV levels, the two datasets can be referenced and can then add functional information, such as tissue characteristics, to the morphology. Especially for low KV datasets HiDynamics significantly increases the detail level and sharpness of images. Dose-optimized Single Source DE When multiple scans of the same region have to be performed, dose protection becomes ever more important. Siemens has introduced a Single Source Dual Energy scan mode that utilizes all dose reduction functionalities without limitations: e.g., CARE Dose4D for real-time mA modulation, or SAFIRE for the reduction of mA through iterative reconstruction. Scanning at half the dose The Single Source DE scan mode consists of two successive spiral scans at different energy levels. In order to avoid doubling the dose, both scans are performed at approximately half dose. As the scan uses regular spirals, all dose reduction features can be utilized without limitations. The excellent capabilities of the Stellar Detector regarding low dose / low signal imaging make possible the industry’s only Single Source Dual Energy scan mode optimized for low dose. 37 Customer Services A range of innovative service solutions that provide the answers to best support you in raising quality and productivity in healthcare.
