Abstract:
A radiation image detecting system, comprising a solid radiation detector comprising a conversion means which converts radiations bearing thereon image information to electric charges, and a two-dimensional image detecting means which detects the electric charges obtained by the conversion,wherein the improvement comprises a high frequency component attenuation means which attenuates high frequency components of the electric charges bearing thereon high frequency components of the image information not lower than a Nyquist frequency, which is defined by the pitches of the two-dimensional image detecting elements, so that aliasing noise due to the high frequency components of the image information not lower than the Nyquist frequency becomes not stronger than 30% of intrinsic noise power at a frequency equal to a half of the Nyquist frequency, further including a transparent conductor disposed over the conversion means, wherein the high frequency component attenuation means is disposed in physical contact over the transparent conductor.
