  • Split-SecondScanningHow often has your daily practice been interrupted or delayed by fragile,sick, or traumatic patients who either cannot hold their breath or becomeimpatient during regular scan procedures? Finding a solution to thesehindrances is what has motivated us to design the world’s fastest CT, byutilizing Dual Source for Flash-like scan speeds of up to 458 mm/s.With Flash Spiral scanning, holding breath and motion lose theirsignificance, making the SOMATOM Definition Flash the optimal patient-friendly CT. We introduce you to the new, cutting-edge of FAST CAREtechnology that raises the standard of your patient-centric productivity,e.g. through FAST Cardio Wizard, that breaks down the restrictions ofprevious CT scanning in cardiology. Today, split-second scanning isproving its value in actual practice. Emergency department trauma scansof an entire body in less than five seconds with dose usually under 5 mSvhave also been made possible by the Flash’s speed. Now, with the help ofthe FAST Spine feature, making the preparation of complex vertebraeand disc reconstructions a matter of one click and 30 seconds, we taketrauma imaging and neurological CT examinations to the next efficiencylevel for earlier and more accurately targeted treatment. 11

  • How it works Flash Spiral Even the most advanced single-source CTs The SOMATOM Definition Flash guarantees are limited in their scan speed by the fast and accurate ED imaging by putting maximum table feed that can be used and you in the position to achieve earlier and still allow the acquisition of contiguous more accurately targeted treatment data. The SOMATOM Definition Flash decisions that positively affect the patients breaks through this barrier primarily by 30-day adverse event rate and reduce simultaneously integrating data from a repeated visits.(2) second source during the scan. By combining this Dual Source technology Revolutionizing the with fastest available hardware triple-rule-out components, including a gantry that rotates at 0.28 seconds, a patient table In case of acute chest pain, scanning that can handle immense table feeds, and with the SOMATOM Definition Flash ultra-fast data transmission technology, significantly saves time because it is now makes possible the fastest scan mode in possible to assess pulmonary arteries, CT history. The result is an unprecedented coronary arteries, and the aorta in a single scan speed of up to 458 mm/s, fast split-second scan. Scientific validation in enough to scan an entire adult patient large cohorts demonstrate impressive in less than four 4 seconds. results. Due to the SOMATOM Definition Flash’s split-second scanning capabilities Increased patient friendliness physicians obtain “motion-artifact-free and accurate visualization” in these Patients who cannot hold their breath or challenging examinations “at a very low suffer from shortness of breath, patients radiation exposure.”(2) Mean scan times are Single-source CT requires slower table feeds to prevent who are restless or impatient, who are 0.7 seconds while a radiation dose of only gaps in the acquired volume (bottom). uncooperative, obese patients or young 4.1 mSv or less is applied.

  • How it works FAST Planning Fastest emergency CT through FAST Planning uses defined automated planning anatomical landmarks to set the correct recon ranges within a large In time-critical emergency situations, scan field of view – as in trauma long scan ranges involving different body imaging – for faster results when regions and organs are common. The every second counts. planning of the scan and reconstruction field of view is prone to error and eat up precious time to diagnosis. FAST Planning focuses explicitly on this critical part of the scan process. Based on the topogram, FAST Planning assists the scan and reconstruction planning to provide an easier, faster, and standardized workflow in CT scanning. The selection of the anatomical region of interest (ROI) from a list automatically defines prospectively the scan and reconstruction ranges. The scan ROIs are automatically detected based on the characteristics of the organ that is to be scanned. In addition, the corresponding scan ranges are proposed in the topogram as well. In the case of head scans, the iso-center is automatically adapted according to the position of the patient’s head to prevent cutting off important information during the emergency examination. 17

  • 22 Defining low dose CT
  • Defining Low Dose CT Applying the lowest radiation dose possible is of the utmost importance for both you and, of course, your patients. Therefore you always want to be assured that you have taken every means available to protect your patient from unnecessary radiation. This desire lies at the heart of our CARE (Combined Applications to Reduce Exposure) research and development philosophy. Consequently, with Siemens’ continuing effort to achieve highest dose protection, the new SOMATOM Definition Flash now combines all features to reduce radiation as low as possible: next to its already outstanding dose protection portfolio from the initial product generation, it now adds a wide range of new and improved dose reduction features. CARE kV, for instance, is the industry’s first tool for automatically solving the complex equation for optimal image quality at lowest possible dose for each individual CT exam while considering tube voltage, tube current, and contrast changes at different voltages and attenuation. This allows you to benefit from the industry’s widest tube voltage range – not only 140 kV for bariatric imaging but now, if necessary, also down to 70 kV where the Definition Flash sets new standards in pediatric safety. Add the first, raw-data-based iterative reconstruction SAFIRE* and define low dose for all body regions to take best care of your patients well-being.*The information about this product is being provided for planning purposes.

  • How it works X-CARE X-ray low Additional dose reduction of up to 40% Siemens has recognized the importance of dose-sensitive scanning, especially for female patients, but also when directly radiating the eye lens or the thyroid gland. A simple but effective approach to lower dose for the most dose-sensitive body regions is partial CT scanning, that has been integrated into dedicated protocols X-ray on of the SOMATOM Definition Flash. It protects these areas from direct X-ray Conventional scanning X-CARE nearly switches the exposure by nearly switching the X-ray applies radiation permanently tube current off within a tube off for a certain range of projections, during the full rotation, thus certain range of projections, while automatically adjusting tube resulting in direct exposure of minimizing direct exposure currents for the remaining projections radiation-sensitive organs, for highly dose-sensitive to prevent deteriorating image quality. for example for the breasts. body regions. The result with X-CARE is reduced sensitive-area exposure up to 40% without loss of image quality.28 Defining low dose CT

  • 34 Dual Source DE for all patients
  • Dual Source DEfor all PatientsIt has always been a CT goal to collect as much information as possible inorder to differentiate tissues. With Dual Energy scanning, the SOMATOMDefinition and SOMATOM Definition Flash open the door to a new worldof characterization, visualizing the chemical composition of material. Theidea of Dual Energy is not new to the CT community. Earlier approaches,including two subsequent scans at different tube voltages or twosubsequent scans at the same position, failed to seamlessly align theimaged anatomy and to capture the same phase of contrastenhancement.Dual Energy was first successfully introduced into clinical practice withDual Source CT, i.e. two X-ray tubes and two UFC (Ultra-Fast Ceramic)detectors mounted at 90 degrees from each other and perfectlysynchronized during scans. And, to date, Dual Source remains the onlymodality that enables the usage of Dual Energy in daily practice at a dosecomparable to a conventional 120 kV scan and with optimum spectraseparation for highest value DE information.With 12 FDA-cleared applications and more than 700 Dual Source CTsinstalled, the number of Dual Energy scans has skyrocketed worldwideand is expected to continue increasing at an even higher rate. DualEnergy with Dual Source CT adds the decisive diagnostic confidence forsustainable and sound treatment decisions – it is the advantage thatproves itself over and over in daily practice. 35

Changing the kV setting 120 kV results in an alteration of photon energy Using the two Z-Sharp STRATON tubes, and a changed attenuation of the Dual Source data acquisition allows for materials scanned. For instance, scanning at least 1,152 projections per rotation Single-source CT only provides one energy level for an object with 80 kV results in a different and spectrum.
