  • X-ray examination apparatus including an image sensor matrix with a correction unit
    Patent number: 6222901
    Abstract: An X-ray examination apparatus utilizes an image sensor matrix for picking up an X-ray image, i.e. for converting incident X-rays into electric charges. The X-ray examination apparatus includes a control circuit for controlling the image sensor matrix so as to form a dark signal. The X-ray examination apparatus also includes a correction unit which is arranged to derive the electronic image signal from the primary image and the dark signal. The electronic image signal represents image information in the X-ray image and has not been disturbed by electric charges which have been read with a delay.
