Experimental hybrid spectral CT with Cramer-Rao lower bound-optimized weighting for quantitative iodine imaging
This work validates a hybrid spectral CT system, comprised of clinical-grade components, acquiring four distinct effective spectra and applying efficient noise-reducing weighting schemes to compare iodine noise and bias against conventional kVp-Switching (kVp-S).
