Technical Implementation of Dual Energy CT (T. Johnson)

posted by Thorsten R. C. Johnson, M.D. | Jan 4, 2010

This third article of our Dual Energy-series focuses on the technical implementation of Dual Energy technology. For Dual Energy scanning, the tube potentials are mostly set to 140 and 80 kVp to obtain the largest spectral difference. Weighted average images are calculated by the image reconstruction system to resemble normal 120 … Read more
