CHALLENGES WITH SINGLE ENERGY CT Tissue characterization Lesion detection (small lesion) Image noise and quality at low kV scanning Complex scanning protocols Multiphase imaging Radiation dose 3 The term “dual-energy CT,” or “DECT,” refers to CT that uses two photon spectra; therefore, DECT is sometimes also referred to as “spectral CT.” In clinical practice today, two different spectra are generated either by switching the voltage of one x-ray tube or by running two tubes at different voltages, and spectral information is gained from two absorption measurements with Material decomposition in dual-energy computed tomography separates high-Z elements from iodine, identifying potential contrast media tailored for dual contrast medium examinations Tobias Fält , Marcus Söderberg , Johan Wasselius & Peter Leander , 2015 , I: Journal of Computer Assisted Tomography. 39 , 6 , s. 975-980 Centre for Innovation, Research and Competence in the Learning Economy, Circle Dual-energy CT techniques are briefly described, and several cases are presented to illustrate how dual-energy CT may be used to help diagnose clinically atypical or asymptomatic gout, differentiat Dual-energy CT (DECT) is one of the most exciting and promising developments in radiology in recent history.

Vi erbjuder bland annat kompressorer, vakuumpumpar, generatorer, pumpar,  Dual energy CT, also known as spectral CT, is a computed tomography technique that uses two separate x-ray photon energy spectra, allowing the interrogation of materials that have different attenuation properties at different energies. In dual-energy CT (DECT), two CT datasets are acquired with different x-ray spectra. These spectra are generated using different tube potentials, partially also with additional filtration at 140 kVp.

However, Kalender et al developed a CT scanner with a prototype apparatus for rapid kVp switching.

During a Dual Source Dual Energy scan, two CT datasets are acquired simultaneously with different kV and mA levels, allowing you to visualize differences in the energy-dependence of the attenuation coefficients of different materials. These images are combined and analyzed to visualize information about anatomical and pathological structures.

The physical principles of dual-energy computed tomography (DECT) are as old as computed tomography (CT) itself. To understand the strengths and the limits of this technology, a brief overview of theoretical basis of DECT will be provided. Specific attention will be focused on the interaction of X-rays with matter, on the principles of attenuation of X-rays in CT toward the intrinsic limits of Se hela listan på news-medical.net The global dual and multi-energy computed tomography (CT) market was valued at US$ 2.6 Bn in 2018, and is expected to expand at a CAGR of 8% during the forecast period of 2019-2029.
