Siemens Introduces Dual Energy Applications Conventional Imaging

Introduced the first set applies to multi-contrast computed tomography system

Following the first to introduce the first set of dual X-ray tube with dual-source CT System SOMATOMDefinition, the Siemens Medical has developed 10 kinds of dual-energy applications. May 13, 2008 to 16 in Las Vegas, multi-row detector CT of the Tenth Annual International Symposium on, Siemens demonstrated the use of dual energy imaging to improve image contrast optimization sectional comparison (OptimumContrast) software. With these innovations in the past limited to certain dual-energy applications of clinical research has been able to use the contrast agent used in a routine examination.

Date, radiologists use of contrast agent during the inspection, to be decided in the final image is to achieve a high contrast or low image noise. About using a lower voltage 80kV generated images, with a clear increase iodine contrast, blood vessels will increase the resolution, but these images usually have a higher image noise. In contrast, the use of 140kV voltage generated images, more suitable to distinguish soft tissue, image noise is often relatively low.

Benefit from optimization of Siemens contrast (OptimumContrast) software, CT system for the first time can be 80 kV and 140kV high-voltage low-voltage advantages of one image into each. OptimumContrast also generated through the use of two different X-ray tube voltage to achieve this goal. In addition, the software also includes a newly developed image optimization algorithms, analysis of 3D data to determine the high-voltage and low voltage image voxel best mixed degrees to the high voltage and low voltage image of the edge and into the sheets of each multi-contrast images . This will be an unprecedented increase of soft tissue containing contrast agents and vascular structure of the display.

"We see the dual-energy imaging software tools and OptimumContrast great potential for integration. This integration can increase the contrast of CT images to improve diagnosis and simplify complex workflows." Siemens Medical CT market and said vice president of sales AndrHartung , "Optimum Contrast software as the conventional dual-energy CT scan imaging has brought the advantage of optimizing contrast agents check all the image quality."

Addition to the new Optimum Contrast software, Siemens will also be multi-row detector CT of the Tenth Annual International Symposium on the display of four recently introduced dual-energy applications:

Siemens SOMATOM Definition dual-energy applications Syngo DE Heart PBV (Perfusion Blood Volume chart) is Siemens SOMATOMDefinition new one dual-energy applications, in the heart of the inspection carried out without a color marker of myocardial perfusion. In addition, a special application of a separate display heart, without displaying other chest structures. Cardiac perfusion imaging is mainly used to determine the scope of the damage after myocardial infarction. Dual-energy CT scan to determine the first by a coronary stenosis and the extent and the resulting reduction of myocardial perfusion and extent of the site.

Joints of patients with gout, the deposition of uric acid crystals will destroy the cartilage and bone tissue, especially in patients with disease for many years. By syngoDEGout dual energy applications, computer tomography can be used for gout first exploration. This new dual-energy applications can help doctors to clearly identify the uric acid crystals in the extremities and monitoring changes during treatment, crystallization conditions.

Syngo DE LungVessels push for a full set of new applications to help doctors pulmonary embolism (sudden blockage of pulmonary artery) in patients suspected of CT. This new application through color marking, detection without perfusion lung blood vessels and tissue. "Lung isolation (LungIsolation)" function can free the lungs to the tissues around the block without the case, assess the perfusion.

Syngo DE Brain Hemorrhage help in cases of cerebral hemorrhage distinction between new and old cerebral hemorrhage. X ray tube produces two energy can help reduce the use of contrast agents. This requires two previous scans. Reduction of contrast agents have two main advantages: no need for plain non-contrast agent examination; patients can avoid the re-scanning the radiation dose.
