It has been possible to digitize analogue images for a number of years--either by the use of a still frame from a video camera, or by scanning a continuous-tone photograph--and to produce output in either print or transparency form, or with the captured image as part of, say, a computer-generated teaching slide. The quality has until now been less than adequate in terms of overall resolution and colour fidelity. It is only recently that true digital imaging has allowed the medical photographer to examine the mechanics of the production of high-quality clinical images and to see if this technology can provide a viable alternative to conventional silver imaging in terms of resolution, colour accuracy, speed, economy and overall usability. This article describes the short-term use of the Kodak Digital Camera System (the DCS) in the clinical studio and assesses the factors stated above.
多年来，将模拟图像数字化一直是可行的——可以通过使用摄像机的静态画面，或者扫描连续色调的照片来实现——并以打印、透明胶片形式输出，或者将捕获的图像作为计算机生成的教学幻灯片等的一部分。到目前为止，就整体分辨率和色彩逼真度而言，其质量还不尽人意。直到最近，真正的数字成像才使医学摄影师能够研究高质量临床图像的制作原理，并探讨这项技术在分辨率、色彩准确性、速度、经济性和整体可用性方面是否能成为传统银盐成像的可行替代方案。本文介绍了柯达数码相机系统（DCS）在临床工作室的短期使用情况，并对上述因素进行了评估。
