Abstract
Disclosed are techniques for performing CT beam hardening correction. The CT beam hardening correction includes scanning a phantom to obtain measured projection data of the phantom and calculating corrected projection data of a measured object according to a calculated beam hardening correction factor, measured projection data of the measured object, a corrected projection data of the measured object, and a relationship among expected projection data of a scanned object.
