Patent ID: 6856670

Claim:
In an X-ray diagnostic installation having an X-ray tube operating by a voltage generator so as to emit X-rays, a solid state X-ray detector on which said X-rays are incident, which generates electrical signals dependent on said incident X-rays, an image system which generates image signals from said electrical signals, and a playback device connected to said image system for displaying a visible image from said image signals, the improvement of said solid state X-ray detector being flexible and comprising: a flexible X-ray converter for converting said incident X-rays into electrical charge; a flexible substrate with a matrix of thin film transistors thereon connected to said flexible X-ray converter for reading out said electrical charge to produce said electrical signals; a flexible housing containing said flexible substrate and said flexible X-ray converter; a measurement device in contact with said substrate which generates a measurement signal indicating a degree of bending of said substrate; and a correction system supplied with said measurement signal for correcting image distortions in said electrical signals caused by bending of said substrate.
