syngo.via - CT Dual Energy Monoenergetic Plus step by step

syngo.via® CT Dual Energy Monoenergetic Plus The syngo.via CT Monoenergetic Plus application class simulates images that are equivalent to images scanned with a single photon energy beam, depending on the energy (keV). By changing the energy (keV), you can enhance the contrast between different materials. Compared to the Monoenergetic viewing mode, Mo- noenergetic Plus provides an improved algorithm for noise reduced images, parallel display of multiple ROIs and their curves, and the ability to save this ROI information for statistical evaluations. 1. From the Patient Worklist, load an appropriate data set into the CT Dual Energy Workflow: • If the examination has been correctly mapped, double click to load Monoenergetic Plus V Resolution • If manual mapping is required, right-click the examination and 2 select Open With > CT Dual Energy Minimum [HU] 950 Default • When data is loaded into syngo.CT Dual Energy, relevant ap- Maximum [HU] 3071 plication classes are also loaded. Select the Monoenergetic Basic Algorithm Calculate Plus application class Export Statistics 2. In the upper right in-segment tool menu, select the Monoenergetic Plus ROI tool, which enables the drawing of ROIs for evaluating the mean CT value as a function of photon energy. Draw an ROI in the tissue of interest.
