摘要: This study presents a homogeneous region localization technique combined with automated evaluation of radiation dose-dependent contrast-to-noise ratio in dual energy abdominal CT. Patient body size was calculated using growing segmentation and used to estimate size-specific dose estimate, are automatically evaluated by proposed technique. Contrast-to-noise turned out be similar between low high tube potential for both pre- post-contrast phases, while is remarkably lower at 80 kVp. Low can recommended reduce maintaining contrast-to-noise.
