Abstract
A radiation reader including a conversion device, and a method of driving the radiation reader. The conversion device includes (a) a pixel including a conversion device for converting an incident radiation into an electric charge, and (b) a reading circuit including at least one field effect transistor for reading the electric charge from the pixel in an amplifying manner as a signal containing a noise. The reading circuit includes first storage means for storing the signal containing the noise, second storage means for storing the noise, and processing means for deriving an output signal not containing the noise based on a first output from the first storage means and a second output from the second storage means.
