  • Patent number: 8681940
    Abstract: An X-ray detecting apparatus constructed as the present invention receives an X-ray passing through a subject during a window time in which the subject is exposed to the X-ray, and converts the X-ray into an electrical signal to output the electrical signal as a video signal. The X-ray detecting apparatus subtracts the offset video signal determined according to the window time in the video signal to generate a real video signal representing the X-ray result for photographing the subject.
