The patient is moved through the CT-scanner more than twice as fast as with any conventional system, and at the same time, requiring a much lower radiation dose than conventional scans. In comparison, the X-ray radiation that the average person is exposed to each year from natural sources amounts to 2 mSv to 5 mSv. The dose values of the new Siemens CT scanner lie far below those of an intracardiac catheter examination, thus opening up possibilities for using CT scanners for routine cardiological examinations.A scan of the entire heart can be performed in only 250 milliseconds, which is less than half a heartbeat. In addition, it is possible for physicians to reliably display a heart with a fast pulse or an irregular heart beat without using beta blockers, thus simplifying the workflow and yielding clinical and financial advantages. The SOMATOM Definition Flash is the only CT scanner on the market that enables the use of noninvasive cardiological diagnostic techniques as routine applications at the lowest possible radiation exposure levels.The second generation of Dual Energy imaging will introduce a new imaging quality. The contrast in CT scans will be increased without having to apply the higher radiation dose previously required. This is achieved via a new, selective photon shield which blocks unnecessary parts of the energy spectrum. It thereby provides improved separation of the two simultaneous scans with low and high photon energy, without causing a higher radiation exposure than would result from an individual, conventional CT examination with only one energy source. Thus, the SOMATOM Definition Flash can always provide a double contrast which, for the first time ever, can also be used to classify the chemical composition of tissues via a CT scan in routine daily work.Another technical development for keeping the patient’s radiation exposure as low as possible is the X-CARE application. For the first time ever, this application selectively reduces the radiation exposure of dose-sensitive anatomical regions, such as the female breast. This is done by switching the X-ray tube assemblies off during the rotation phase in which the anatomical regions concerned are most directly exposed to radiation. In this way, it is possible to reduce the radiation exposure of individual anatomical regions by up to 40 percent.Furthermore, an adaptive dose shield blocks irrelevant prespiral and postspiral radiation with dynamic diaphragms, thus ensuring that only a minimum and clinically essential radiation exposure occurs. This enables an additional 25 percent reduction of the dose required for routine examinations. The CARE Dose4D software, which analyzes the individual cross-sectional anatomy in real time and adapts the emitted X-ray dose accordingly, also helps to reduce radiation exposure.In addition, Siemens CT Acute Care Engine provides a complete clinical portfolio for imaging emergency patients from head to toe. Using fast, direct 3D reconstruction, images can be reviewed before the patient is off the table. The SOMATOM Definition Flash, in combination with CT Acute Care Engine, streamline clinical workflow for cardiac, vascular, musculoskeletal, and stroke evaluation, turning data into diagnostic outcomes within minutes. By combining CT scanner features and programs, solutions can be designed to meet and exceed a site’s acute care needs.For more information: www.siemens.com/healthcare FacebookTwitterLinkedInPrint分享 Videos | AAPM | July 29, 2019 VIDEO: Trends in Medical Physics at the AAPM 2019 meeting … read morelast_img
