Chest X-Ray Analysis by Computer Final Report.
NIOSH 1972 Sep:6 pages
A study program is described which is concerned with the investigation of chest x-rays containing various classifications of pneumoconiosis. Samples of x-rays are digitized using a programmable light source, and the digitized data are then processed in various ways and subsequently applied to the CRT scanner system to generate photographic images. The purpose of the transformations is to determine the basic characteristics of typical chest x-rays with regard to resolution and gray scale content; to present the data in a manner which accentuates or facilitates the classification of pneumoconiosis, and to determine the necessary hardware and specify its operating characteristics for ultimate use as a computer input system. Results of the investigations are included in the report with the images recorded during this study. (Contract No 099-72-0028)
