Abstract

The effect of polychromatic x-rays on image reconstruction in helical cone-beam computed tomography is investigated. A pre-reconstruction dual-energy technique is developed to reduce beam-hardening artifacts and enhance contrast in soft tissue. The effect of realistic signal noise on the dual-energy method is studied.
