An iodine-calcium separation analysis and virtually non-contrasted image generation obtained with single source dual energy MDCT

摘要

Dual energy CT enables the differentiation between various materials by analyzing their unique attenuation spectral response. These responses are represented as vectors on an image-based energy map. Practically, this spectral information can be very noisy requiring further analysis. Furthermore, the material response vectors may be affected by beam-hardening and varied between images.
