Abstract: The CT technique applied to ICF has been developed and a three dimensional (3D) image reconstruction program(CT3D) was performed.The program CT3D is used to numerically study the 3D reconstructed images of target's plasma by using a multiplicative algebraic reconstruction technique (MART) from five pinhole camera images obatined along different sight directions on ‘Xingguang Ⅱ’ device,so that 3D images of ICF's tagets are obtained.The simulated results show that the CT technique can be applied to ICF experiments.
