摘要
X射线机的发展目标是获得更清晰的图像,而X射线管的有效焦点尺寸是决定X射线成像质量的一个重要因素。本文主要通过测量原理、测量条件和测量方法的描述,采用以狭缝法为基本原理的RFM实时焦点检测仪,对X射线机(DR)的有效焦点进行测量。
The development goal of X-ray apparatus is to obtain clearer images, and the effective focus size of X-ray tube is an important factor to determine the quality of X-ray imaging. In this paper, through the description of measurement principle, measurement conditions and measurement methods, the RFM real-time focus-measuring instrument based on slit method is adopted, and the effective focus of X-ray apparatus（DR） is measured.
