文摘
- •
An experimental basis for spectral optimization of iodine-enhanced CT is presented.
- •
Mutually consistent measurements are performed at an anthropomorphic body phantom.
- •
Data analysis does not use prior knowledge on noise characteristics.
- •
Low voltage CT substantially reduces radiation exposure while maintaining contrast.
- •
Characteristic curves are derived that help to optimize iodine-contrast CT.
