X线摄影放大装置的研制及临床应用

介绍了X线摄影放大装置，利用X线几何投影和光学成像原理，采用单片机软件编程，通过光耦技术和变频调速技术，实现仪器的自动控制。临床试验表明，该X线放大装置用于摄取开放大人体小部位的病灶是可行的。

The development of an amplifying device for X-ray and its clinic application

This paper introduces an amplifying device for x-ray, which is designed by making use of the principles of the x-ray geometry projection and optical imaging. Making use of programming superiority of the single-chip microcomputer, the instrument can be controlled automatically through the optical coupling technique and the frequency conversion speed-adjusting technique. It shows that the instrument was practical to radiograph a small focus and amplify it in clinical practise.
