摘要
本文报道了对锥形束X线下的直接体积重建进行了实验研究。该实验装置包含了铝棒、有机玻璃和空气棒的实体模型、锥形束X线源、旋转系统、荧光屏、图像增强器、CCD摄像机、图像采集器和微型计算机、实验结果表明,利用现有的X线诊断设备,可进行直接体积成像。
Application of DVR is investigated with the X-ray equipment under single circle imaging geometry. A real volume model that consists of aluminum bar. lucite and air bar is designed. A prototype imaging system that includes X-ray cone - beams ource. rotating system , fluorescent screen, image intensifier,TV camera,image acquisitor and rnicrocomputer is constructed. The experimental results show that DVR with the current simple X-ray equipment is of interests and values.
