基于视频采集的超声图像采集系统设计实现

目的采用视频采集卡实现超声图像采集与数字化存储传输。方法采用加拿大Matrox公司的RGB彩色视频采集卡及附带的MIL6．1函数库，用VC 6．0编制图像采集程序，从超声机的视频输出端获取视频信号。传入微机经采集卡进行模数转换。实现图像数字化。结果应用MIL6．1和VC 6．0编制程序实现了超声图像的采集存储，并可经局域网传输，加入数据库功能后，可与PACS服务器连接，实现图像的远程存储调阅。结论该系统结构简单。造价不高，采集程序工作于Windows 2000环境下，界面友好。使用方便。

The design and realization of the ultrasound image capture system based on video capture

Objective: To develop a method of using video capture card to realize the capture and digitalized store and transmission of ultrasound images. Methods: By using the Matrox RGB colour video capture card and the attatched MIL6.1 function base from the Canadian Matrox Corporation,with VC++6.0 used to develop image capture program, video signals were acquired from the video output port and then were fed to computers and by means of A/D translation the digitalzation of ultrasound images was realized. Results: By programming with MIL6.1 and VC++6.0, we realized the ultrasound image capture and store system and the images could be transmitted by LAN. The system could connect with PACS server with the database functional model and we could acquire the images remotely. Conclusion: This system is simple and doesn't cost much, the capture program works under Windows 2000 professional environment and the friendly user interface makes it very convenient to use.
