The application status of computer tomography(CT)in nondestructive testing high explosive charges is reviewed.The U.S.Department of Energy (DOE)subordinated LLNL,LANL and Pantex Plant carried on a series of work in this field in cluding setting up CT scanners, formulating experimental methods and image reeonstruction, etc,The compressed cylindric and hemispheric charges of PBX-9502, PBX-9501 and LX-10-2 were tested to evaluate the feasibitity and superiority of CT as a nondestructive testing method for qualification of high explosive charges.
