Title:
METHOD AND DEVICE FOR PROCESSING X-RAY IMAGE
Document Type and Number:
Japanese Patent JPS5910841
Kind Code:
A
Abstract:
A device for and method of X-ray processing in which a constant adjustable signal value is subtracted from a video signal of an X-ray image in order to correct the video signal for the effects of inherent scatter. The adjustable signal value depends on the X-ray tube voltage, the nature of the object to be examined, the field size etc. so that it is preferably dependent on the X-ray exposure parameters. The video signal is preferably converted into a logarithmic value by means of a logarithmic table which is dependent on the adjustable signal value (or actually on the exposure parameters).
