2种X线机简易曝光装置的设计及应用

摘要

In this paper, we design a delay unit which can adjust the delay time and a infrared emitting and receiving device. 555 Timer and SC2272 are the cote unit of these devices respectively. These devices were installed in the X-ray system, this allowed the technicians be far away from the machine and protect ihe health of technicians.%本文介绍了一种能调节延迟时间的延迟装置和一种红外发射接收装置,分别以555定时器和SC2272为核心,加装在床边X线机上,实现一键启动曝光功能.可让技师在机器曝光时处于离机器较远的位置,保障了放射技师的身体健康.
