| 英文摘要 | For the empirical beam hardening correction in computerized tomography (CT), it is necessary to measure an attenuation curve for the material. The attenuation curve depends on the X ray machine operation parameters and object material, etc. If any measuring condition changes, a new attenuation curve has to be measured. This approach is time consuming and difficult to implement. A new method of beam hardening correction is presented in this paper, which is based on Monte Carlo simulation of the attenuation characteristic. An aluminium object is scanned and the projection data is corrected by the empirical beam hardening correction and by the simulation based correction. The results of the reconstructed images confirm the correctness of the simulation based method. The simulation based correction has been applied successfully to CT projection data of several test samples, with the material of aluminum, steel and copper. |
