摘　　要：数字减影成像(DSA)是一种在医学诊断以及介入治疗中起重要作用的技术。由于通常的数字减影算法效果并不理想,该文提出了一种新的减影算法———基于分段对数变换的DSA算法。该方法已用VC编制成软件,并且装备数字化X-射线装置,在计算机实验及临床实践中都取得了满意的效果。Digital subtraction angiography is an important technology in both medical diagnoses and interposal therapy.For the usual method of DSA has not good performance,a new algorithm based on subsection logarithm transform is presented in this paper.This method has been realized in VC program,which has been installed in X-Rays medical de-vices with satisfying results in both experiments and practice.
