摘要
本文介绍一种数字减影血管造影(DSA)系统。该系统可实现迭影剂注射后的造影图象与注射前采集的蒙片图象作实时减影运算,同时具有动态采集、回放及图象硬件放大、漫游等功能。其最大图象存贮量可达128Mbit。系统经临床使用认为,基本上可满足目前开展DSA工作的需要。
The paper introduces a system of the digital subtraction angiography (DSA), which can complete the subtraction of live image with mask image in time.The system has the function of image sampling and live display and the function of image magnifying and image shifiting by hardware. The largest frame store capeciting can reach 128Mbit, and can basically meet the needs of DSA work in clinics.
