采用乘代数重建法(MART)和加代数重建法(ART)

编制出三维图像重建程序CT3D

通过对“星光Ⅱ”装置的激光等离子体进行X光针孔成像的五个方位

对三维重建问题进行数值模拟

计算结果表明MART比ART的重建精度高

能满足诊断误差δI/I小于10%的要求。

Abstract

A CT technique applied to ICF has been developed and a three-dimensional (3D) iamge reconstruction program(CT3D) programed in this paper.The program CT3D is numerically studied the 3D reconstructed images of target's plasma by using a multiplicate algebraic reconstruction technique(MART) and algebraic reconstruction technique(ART) from five pinhole camera images obatined along different sight directions on ‘Xingguang Ⅱ'device

so that 3D images of X-ray emitted by laser plasma are obtained.The simulated results showes that athe MART's reconstructive accurance is better than ART's and MART can meet the requirement that diagnostication error

δI/I

is lower than 10%.
