介绍一种基于Visual Basic语言的数字化眼底血管造影图像系统(DFFAS),提供了系统的硬件组成和软件设计思路。该系统以现有的荧光眼底镜为基础,通过采用专业数字相机、视频采集卡,结合应用软件,动、静态采集眼底血管造影图像,最终实现眼底信息的数字化采集、处理和报告管理等一系列功能。实验结果表明,该系统采集图像清晰,操作简便,可广泛应用于临床诊断和教学。 This paper introduces a digital fundus angiography system (DFFAS) based on Visual Basic language, and provides the system hardware and software design ideas. Based on the existing fluorescent fundusoscope, the system collects the fundus angiography images dynamically and dynamically by using a professional digital camera, video capture card and application software, finally realizing a series of digital acquisition, processing and report management of fundus information Features. The experimental results show that the system has clear image acquisition, easy operation and can be widely used in clinical diagnosis and teaching.
