Chest X-ray Analysis by Computer

摘要

This report describes a study program which was concerned with the investigation of chest x-rays containing various classifications of pneumoconiosis. Samples of x-rays were digitized using a programmable light source (a computer-controlled CRT scanner). The digitized data were then processes in various ways and subsequently applied to the CRT scanner system to generate photographic images. The purpose of the transformations was to (1) determine the basic characteristics of typical chest x-rays with regard to resolution and gray scale content, (2) present the data in a manner which accentuates or facilitates the classification of pneumoconiosis, (3) determine the necessary hardware and specify its operating characteristics for ultimate use as a computer input system (digitization system). The results of these investigations are included in this report, along with the images recorded during this study.
