Abstract :
Dual-energy x-ray computed tomography (DECT) has proved its potential in eliminating beam-hardening artifacts from reconstructed images. The method typically involves two successive scans with different x-ray tube voltage settings. This work proposes a new approach to dual-energy through x-ray beam filtration that requires only one scan and a single tube voltage setting.
