syngo.via CT Dual Energy Overview

Singlecut dual energy is an image analysis software for standardized and automated dual energy image creation for reproducible results and efficient reading of dual energy computed tomography and quantum CT images. Singlecut dual energy is designed to operate with CT images based on two different X-ray Spectra. The various materials of an anatomical region of interest have different attenuation coefficients, which depend on the energy used. These differences provide information on the chemical composition of the scanned body materials. Single CTC dual energy combines images acquired with low and high energy Spectra to visualize this information. Depending on the region of interest, contrast agents may be used. The post processing application, SINGO CTC dual energy supports data acquired with the following scan modes. Dual source, dual energy. Dual spiral or twin spiral, dual energy twin beam, dual energy quantum spectral imaging with 120KV and 140KV. For example quantum plus scan mode at Newton Alpha systems. Depending on the scan mode used and the licenses purchased, the available tools, functions and the application classes of SINGO CTC, dual energy are different. Depending on the body region and the presence of contrast agent, the system will choose a specific application profile consisting of a subset of application classes that best suits the patient's procedure. You can change the default application profiles in the configuration panel. At the top of these dedicated applications there is a subset of common dual energy tools with basic functionalities. Let's take a look at how you can get the most out of them. When you open a dual energy data set, a mixed image is displayed as a combination of the low and high KV data. At the bottom of any of the MPR segments, a slider allows you to change the mixing ratio according to your needs. For example, move the slider towards the high value to reduce noise or move it towards the low KVP value to enhance the contrast of the image. If you want to compare both series simultaneously, open the layout gallery and select the corresponding side-by-side layout. Two additional options are available to help you enhance the contrast to noise ratio of your data. Optimum contrast and monoenergetic. The Monoenergetic mode simulates images that are equivalent to images scanned with a single photon energy beam, depending on the energy Kev value. This is especially interesting if you want to enhance the conspicuity of lesions. For a more comprehensive evaluation, you can set a region of interest monoenergetic, which you can find in the upper right corner menu in the MSR segments. The purple bar shows the current monoenergetic level. The white curve shows the attenuation of the tissue inside the region of interest at the different energies. The blue curve shows the contrast to noise ratio for the iodine. So you can use this curve as guidance to pick the Kev level with a maximum contrast to noise ratio. Monoenergetic could also be very helpful for reducing metal artifacts. Notice how you can improve it by shifting the reconstruction to the area between the white dashed lines recommended for prosthesis imaging.
