摘　　要：现行医疗仪器仪表的控制系统多数采用单片机实现,普遍存在操作烦琐、显示不直观、数据共享性差等缺点。针对上述情况,采用FPGA数字信号处理板和ARM计算机板实现了一款安全、有效且便于图像采集及共享的医疗仪器图像诊断数据采集器。实验结果表明,该采集器能够采集VGA、DVI等格式的视频、图像信号,并将其转换、压缩,有效地实现了医疗信息传输及共享。The current medical equipments mostly adopt SCM to fulfill on control system,which commonly reveals some problems like tedious operation, unintuitive of displaying,poor data sharing and so on. Upon these problems,the passage tells us that FPGA digital signal processing board and ARM computer board have worked out a medical image diagnostic data acquisition equipment which is really safe and effective, and also convenient of image collecting and sharing. The ex- periment shows that this collector could be able to capture video and image signals of any other forms,besides VGA and DVI,and then compress and transfer them effectively to make medical information transmission and share come true.
