DEVICE FOR AND METHOD OF X-RAY IMAGE PROCESSING |
摘要 |
<p>16 A device for and a method of X-ray image 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 on the actual exposure parameters).</p> |
