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 cubs #17 blue jersey 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 cubs #17 blue jersey structure of the display.
