Dual energy powered by dual source CT. You have many options today when it comes to spectral imaging applications, including fast or slow cavey, switching, dual layer detectors, and dual source dual energy CT, single source cavey switching lets you achieve reasonable quality results in most situations, but not without speed compromises, patient size limitations and spectral blurring. Additionally, the quantity of Ms remains constant during cavey switching. Leading to a higher than necessary dose. Dual layer detectors enable faster scan speeds than cavey switching, however they are not precise enough to properly distinguish between high and low energy photons and therefore suffer from poor spectral separation. The dose is also high because dual layer detectors require fixed power settings and Ms quantities throughout the acquisition. Dual source CT scanners offer a dual energy mode that lets you dial in different cavey and Ms settings for each tube so you can cover large volumes at high speeds. When it comes to dose, the raw output of a dual source CT scanner is compara bulto, a standard single source acquisition. But you actually get an even lower dose thanks to the built-in tin filter. That in filter doesn't only lower dose. It also enhances spectral separation and this naturally improves image quality. With dual source ET you can achieve dual energy acquisitions with optimal dose speed and quality. Dual energy powered by dual source CT. Part of our unmatched scan modes. Dual source ET ready beyond tomorrow.
