Siemens Introduces Dual Energy Applications for General Imaging

First Multi-Contrast System Introduced for Computed Tomography

Following the introduction of the first-ever dual-source CT system, Somatom Definition, with two X-ray tubes that simultaneously generate different energies, Siemens Healthcare has developed ten dual-energy applications.

At the 10th Annual International Symposium on Multidetector-Row CT in Las Vegas to be held from May 13 to 16, 2008, Siemens will present its Optimum Contrast software, which brings new levels of contrast to sectional images created with dual-energy applications. Thanks to these innovations, dual-energy applications, which were previously reserved for special clinical investigations, can be now be used in a broad range of routine examinations that involve contrast medium. Until now, radiologists performing examinations with contrast medium had to decide whether they wanted to see more contrast or less image noise in the final images. While images taken at lower voltages of approx. 80 kV (kilovolt) resulted in a higher resolution of the displayed vessels due to the significantly increased iodine contrast, these images always featured a higher level of image noise. In comparison, images taken at a voltage of 140 kV are more suitable to differentiate soft tissue and image noise tends to be minor.

Thanks to the Optimum Contrast software of Siemens, CT systems can now, for the first time ever, combine the advantages of low and high voltage values of 80 and 140 kV in every image. Optimum Contrast is made possible by the use of two X-ray tubes that are capable of generating different voltages simultaneously. In addition, the software contains newly developed image optimization algorithms, which analyze the 3D data and determine the optimal mix of high and low voltage benefits for every image voxel to combine the best of both worlds in multi-contrast images. This makes soft tissue and vascular structures containing contrast medium more recognizable than ever.

"We at Siemens see a vast potential for Dual Energy imaging combined with tools such as Optimum Contrast to provide a dimension of contrast in CT, improving diagnostic outcomes and simplifying complex workflows," says André Hartung, Vice President Marketing and Sales, Business Unit Computed Tomography, Siemens Healthcare. "Optimum Contrast adds the benefits of dual-energy imaging to routine CT scans and optimizes the image quality of all contrast medium examinations."

In addition to its new Optimum Contrast software, Siemens will also present four recently introduced dual-energy applications at this year's 10th Annual International Symposium on Multidetector-Row CT: Dual-Energy Applications for Somatom Definition from Siemens One of the new Dual Energy applications for the Somatom Definition from Siemens is syngo DE Heart PBV (Perfusion Blood Volume), which provides color-marking of nonperfused parts of the myocardium during cardiological examinations. Moreover, a specific application allows for the isolated display of the heart, for example without thoracic structures. Heart perfusion is examined primarily after an infarction to determine damaged areas of the organ. DE CT for the first time allows for detecting the presence and level of stenosis as well as the location and extent of the resulting reduced perfusion in the myocardium in a single scan. Deposits of uric acid crystals in the joints of gout patients may damage the cartilaginous and osseous substance, particularly if the disease has been chronic for several years. With syngo DE Gout, computed tomography can for the first time be used to detect gout.

The new DE application assists physicians in clearly identifying uric acid crystals in the extremities and monitoring changes in the crystals in the course of treatment. syngo DE Lung Vessels provides a whole series of new applications to assist physicians in CT examinations of patients with suspected pulmonary embolism – a sudden occlusion of blood vessels in the lungs. The new applications allow for detecting non-perfused pulmonary blood vessels and tissue through color-marking. The application "Lung Isolation" isolates the entire organ to assess the perfusion situation without obstructing adjacent organs.

syngo DE Brain Hemorrhage assists in the distinction between new and old hemorrhages in the event of cerebral bleeding. The two energy levels of the X-ray tubes are used to fade out the contrast medium. In the past, this had required two scans. The CM subtraction offers two advantages: A non-CM enhanced examination is no longer necessary, and the patient is spared the radiation dose of a second scan. Siemens Healthcare is one of the world’s largest healthcare solution providers.

The company defines itself as a medical solution provider with core competences and innovative strengths in diagnostic and therapeutic technologies as well as knowledge processing, including information technology and system integration. With its acquisitions in the area of laboratory diagnostics, Siemens Healthcare has become the first fully integrated diagnosis company to combine imaging and laboratory diagnosis, therapy solutions and medical information technology and complement these with consulting and customer services.

Siemens Healthcare provides solutions for the entire supply chain under one umbrella – from prevention, early detection and diagnosis to therapy and aftercare. Siemens Healthcare currently has around 49,000 employees worldwide and is represented in more than 130 countries. During fiscal 2007 (ending on September 30), Siemens Healthcare achieved a total sales volume of 9.85 billion euros and incoming orders totaling 10.27 billion euros. The Group earnings amounted to 1.32 billion euros.

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
