| Abstract: | The envelope curve artifacts in SRM’s tomographical image was studied, and FBP reconstruction algorithm was introduced. The reasons that caused the envelope curve artifacts in SRM’s tomographical image were analyzed, and the corresponding solutions were provided. Then the computer simulation proved the method to be corrected and the test was done and an ideal result was obtained. |
