Abstract

A digital system of video signals of astronomical use was developed to be applied in the field of radiology. The images were obtained from radiologic films by means of a standard video camera. The minimal specifications of the digital images for use in radiology are as follows: a) 2.5 lpm spatial resolution, b) a digital resolution of 8 bits (256 gray levels). Images (194 by 154 mm in size) can be obtained. The software processing was adapted for treatment of the images in radiology.

摘要

一种用于天文学的视频信号数字系统被开发出来，以应用于放射学领域。图像是通过标准摄像机从放射学胶片上获取的。用于放射学的数字图像的最低规格如下：a）2.5线对/毫米的空间分辨率，b）8位（256个灰度级）的数字分辨率。可以获得尺寸为194×154毫米的图像。软件处理经过调整，以用于放射学图像的处理。
