Abstract

An image recording medium includes: a support which is transparent to radiation for use in recording, and resistant to shock; a wavelength conversion layer which contains an organic binder and a fluorescent material which converts the radiation into visible light; a first electrode layer which is transparent to the visible light; a recording-side photoconductive layer which exhibits photoconductivity when the recording-side photoconductive layer is exposed to the visible light; a charge storage region which stores electric charges which are generated in the recording-side photoconductive layer in response to exposure to the visible light; a reading-side photoconductive layer which exhibits photoconductivity when the reading-side photoconductive layer is exposed to reading light; and a second electrode layer which is transparent to the reading light.

Claims (11)

1. A radiographic-image recording medium comprising:

a support which is transparent to radiation for use in recording, and resistant to shock;

a wavelength conversion layer which is formed under said support, and contains an organic binder and a fluorescent material which converts said radiation into an electromagnetic wave for use in recording, where the electromagnetic wave belongs to a first wavelength band different from a second wavelength band to which the radiation belongs; and

a photoelectric conversion layer which is formed under said wavelength conversion layer, and contains a substrate and at least one photoelectric element which photoelectrically converts said electromagnetic wave into at least one electric signal, where the substrate includes a plate of a shock-resistant material and a thin glass film formed on the plate, and the at least one photoelectric element is arranged on the thin glass film.

2. A radiographic-image recording medium according to claim 1 , wherein said plate and said support are made of materials having approximately identical thermal expansion coefficients.

3. A radiographic-image recording medium according to claim 1 , wherein said wavelength conversion layer and said photoelectric conversion layer are bonded together through a viscoelastic material which is transparent to said electromagnetic wave.

4. A radiographic-image recording medium comprising:

a support which is transparent to radiation for use in recording, and resistant to shock;

a wavelength conversion layer which is formed under said support, and contains an organic binder and a fluorescent material which converts said radiation into an electromagnetic wave for use in recording, where the electromagnetic wave belongs to a first wavelength band different from a second wavelength band to which the radiation belongs; and

a photoelectric conversion layer which is formed under said wavelength conversion layer, and contains a substrate and at least one photoelectric element which photoelectrically converts said electromagnetic wave into at least one electric signal, where the substrate is realized by a thin glass film, and the at least one photoelectric element is arranged on the substrate.

5. A radiographic-image recording medium according to claim 4 , wherein said wavelength conversion layer and said photoelectric conversion layer are bonded together through a viscoelastic material which is transparent to said electromagnetic wave.
