The Minimum Perceptible Contrast of Moving Object in Diagnostic X-ray Television

Abstract

The minimum perceptible picture of a moving object in diagnostic X-ray television was calculated using a partly modified Morgan's formula, which has been for a stationary object.
Calculations on the contrast parameters were made for combinations of a 9-inch X-ray image intensifier tube with some kinds of vidicon type camera tube, in image speed range of 0-6.7 o/s. An experimental observation was made about one combination.
The observed data showed considerably good agreement with calculated ones.
