摘要

生产胶片的化学制品企业富士胶片(当时)在世界上首次成功地将x射线照片数字化,并于1983年将计算机放射照相技术(CR)商业化。除了消除x射线工作中的暗室工作,提高x射线工作和诊断的效率外,该CR还为医院图像信息联网和计算机附加诊断支持铺平了道路。如今,数字x射线的机理已经确立,并为很多人所熟知,但在70年代后半期CR的发展刚刚起步时,还没有先例。在本文中,我们将首先回顾这种CR的发展过程,然后我们将概述数字x射线探测器和图像处理技术的发展,并介绍我们所挑战的技术来估计人体中的散射x射线。

[A Challenge of Digitalizing the X-ray Film Image, and the Recent Technical Trends].

Fuji Photo Film (then), a chemical manufacturer that manufactures film, succeeded in digitizing X-ray photographs for the first time in the world, and commercialized Computed Radiography (CR) in 1983. In addition to eliminating darkroom work from X-ray work and improving the efficiency of X-ray work and diagnosis, this CR also played a role in paving the way for networking of image information in hospitals and for computer-added diagnostic support. Nowadays, the mechanism of digital X-rays has been established and is known to many people, but there was no precedent in the latter half of the 1970s when the development of CR was started. In this paper, we will look back on the development process of such CR first, then we will outline the evolution of digital X-ray detectors and image processing technology, and introduce the technology we have challenged to estimate scattered X-rays in the human body.
