Our Dual Energy CT (DECT) scanners offer a seamless solution with optimized scanning technologies and automated results. This lets you visualize, characterize, and quantify various materials in a personalized and consistent way for virtually all patients and a wide range of clinical questions.

Dual Energy spectral imaging supports you in making confident diagnostic and treatment decisions based on answers only available with Dual Energy. This helps you to impact clinical outcomes and deliver optimal care for your patients.

In contrast to standard computed tomography scanners, Dual Energy CT scanners produce image sets with two different X-ray spectra to characterize materials with precision while highlighting abnormalities in the body.

syngo.CT DE Monoenergetic Plus simulates images that are equivalent to images scanned with a single photon energy beam, depending on the energy (keV). By changing the energy (keV), you can enhance the contrast between different materials. syngo.CT DE Monoergetic Plus provides a range of keV values from 40-190 keV.

syngo.CT DE Virtual Unenhanced allows you to visualize the contrast agent concentration in softbody tissue. The application generates virtual non-contrast (VNC) images bysubtracting iodine from the Dual Energy data sets. The VNC images can be usedfor baseline density measurements.

syngo.CT DE Lung Analysis combines Lung Vessels and Lung PBV. Lung Vessels is designed to visualize the iodine enhancement in pulmonary vessels. Different colors are assigned to differentiate between perfused and non-perfused pulmonary arteries. Lung PBV (Perfused Blood Volume) is designed to visualize and quantify the iodine uptake in the lung parenchyma.

syngo.CT DE Direct Angioautomatically removes bone or dense plastic from CT angiography (CTA) datasets. The prerequisite for a bone removal is the decomposition of the materialinto its component parts: blood, contrast agent, and bone.

syngo.CT DE Bone marrow allows you to visualize the bone marrow composition which is based on non-enhanced CT data. The application generates virtual non-calcium (VNCa) images by subtracting calcium from the Dual Energy data sets.

syngo.CT DE CalculiCharacterization visualizes the chemical differences between kidney stones bydecomposing the kidney stones into its component parts: tissue, uric acid, andoxalate (calcium stone).

At the same time, you benefit from the automatic selection and the right combination of the scan settings. Multiple kV levels let you adapt to the patient's size,with a large spectral separation means even the most demanding exams, like visualizing bone marrow edemas, are possible. The dose level of a Dual Source CT scanner is comparable to a single-source acquisition, but the built-in tin filter enables even lower doses than a conventional 120 kV CT scan.

During a Dual Source Dual Energy scan, two CT datasets are acquired simultaneously with different kV and mA levels, allowing you to visualize differences in the energy dependence of the attenuation coefficients of different materials. These images are combined and analyzed to visualize information about anatomical and pathological structures.

TwinBeam Dual Energy (TBDE) CT allows simultaneous acquisition of high and low kV datasets in a single spectral CT scan by splitting the X-ray beam with two filters, one made of gold and the second made of tin, before it reaches the patient, enabling high-contrast dynamic applications.

The TwinSpiral Dual Energy CT scan mode acquires two consecutive spiral data sets at different kV and mA levels in one easy-to-understand UI timeline. The additional tin filter brings improved material separation to the Dual Energy applications.

CARE kV, a fully automated feature that tailors the tube voltage to the individual patient and clinical task, complements existing dose reduction technologies for dose-neutral Dual Energy acquisitions without compromising image quality.

Image quality is crucial for reliable DECT imaging since dual energy data processing is sensitive to small changes of the Hounsfield units. Relevant criteria comprise the spectral separation and temporal coherence of the low and high energy data, as well as the temporal and spatial resolution of the CT images, but of course also the dose efficiency or the workflow aspects play an important role in enabling efficient DECT imaging in daily routine.

The single energy gray-scale image (indicated on the left) does not allow for the differentiation of the two materials. Spectral imaging with inferior spectral separation (middle image) allows material differentiation but with limited differentiation (resulting in noise in the green/orange material space). As indicated by the right image, using Dual Source Dual Energy CT or TwinSpiral Dual Energy results in excellent spectral separation with clear differentiation.

Dual Energy spectral imaging can provide additional diagnostic information, but this should not come at the expense of an increased patient dose compared to a conventional single energy examination. Siemens Healthineers Dual Energy CT solutions incorporate all state-of-the-art dose reduction features like tube current modulation or iterative reconstruction to allow dose-neutral spectral imaging acquisitions.

Rapid Results enables direct communication between syngo.via and SOMATOM CT scanners, triggering zero-click postprocessing within the selected scan protocol. In that way, syngo.via automatically creates and sends ready-to read results to the PACS. Rapid Results will automatically generate standard visualizations of different anatomies in any required orientation and thickness for all Dual Energy applications.

By fusing low- and high-kV data into the DICOM conformant spectral imaging data format, Spectral Post-Processing (SPP), data and transfer times to PACS are reduced. In your PACS, the SPP dataset shows a single DICOM dataset either as Mixed or Monoenergetic Plus images while keeping the low and high Dual Energy information intact. SPP also enables Interactive Spectral Imaging and gives the user retrospective access to the encapsulated spectral data at any time.

myExam Companion smoothly navigates users through spectral imaging CT examinations by sharing built-in expertise, characterizing real-time patient input, and adjusting key parameters to each patient. It also guides you to Dual Energy reconstructions, such as Iodine Maps or Virtual Non-Contrast, which are PACS-ready. This is valuable for radiologists, giving them additional information to work with.

Recon&GO standardizes results by automatically generating the most appropriate DE inline results in any required orientation and thickness. Just define your workflow once and let Recon&GO produce the decision basis.

Recon&GO offers full freedom of recon parameters (e.g. kernels; recon options, such as different orientations, including oblique), further multiplanar reconstructions, and quantification of DE-related parameters.

syngo.CT Dual Energy allows for retrospective interaction of Dual Energy data and empowers users to customize the Dual Energy analysis to the clinical question by, for example, changing keV levels or the display of Fat Maps.

Built in conjunction with shipbuilder Fjellstrand, Siemens Energy installed the complete electric propulsion system and put up charging stations with lithium-ion batteries which are charged from hydro power.

Imagine a patient being rushed to the ER after an accident or a cardiac arrest and not being able to get a critical test with diagnostic equipment in these split-second, life-and-death scenarios. Maximizing availability, or uptime, of equipment, therefore, assumes top priority.

Healthcare 4.0 is all about gathering relevant and valuable data and using it in applications that translate into improved healthcare management, efficiency and cost-control. In particular, using data analytics to bolster predictive maintenance of equipment can help ease the workload of healthcare service providers so that they can spend more time focused on their patients.

Siemens Healthineers is a global medical equipment manufacturing company with a presence in more than 70 countries. There is an installed base of about 600,000 active systems around the world, allowing for roughly 240,000 patient touch points every hour.

Many of the systems are remotely connected to Siemens Healthineers, e.g. for the purpose of predictive and reactive maintenance. The logistics of managing the significant amount of machine data generated is staggering.

Modern medical equipment is typically highly complex with a lot of specialized parts. Healthcare providers invest in such equipment in order to provide excellent care to their patients. When the equipment fails, it not only inconveniences patients who need to reschedule their tests, it also proves to be challenging for healthcare providers who want to provide the best possible care.
