May 15, 2008 - Following the introduction of the dual-source Computed Tomography (CT) system, SOMATOM Definition, with two X-ray tubes that simultaneously generate different energies, Siemens has developed 10 dual energy (DE) applications.
At the Annual International Symposium on Multidetector-Row CT this week in Las Vegas, Siemens is presenting its Optimum Contrast software, which reportedly 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 now be used in a broad range of routine examinations that involve contrast medium.
CT systems can now, for the first time ever, combine the advantages of low and high voltage values of 80 kV and 140 kV in every image using Siemens Optimum Contrast software. 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, according to the company.
