Abstract
For a radiation image converting panel according to the present invention, a converting portion that converts a radiation image to an optical image is formed on a support for which a dielectric multilayer film is formed on a metal reflector, and the dielectric multilayer film includes at least a first dielectric layer that is in contact with the metal reflector and a second dielectric layer that is formed on the first dielectric layer and has a higher refractive index than that of the first dielectric film layer to light emitted by the converting portion.
Claims12
A radiation image converting panel including a converting portion that converts a radiation image to an optical image on a support,
- the support comprising:
- a metal reflector;
- and
- a dielectric film mirror including at least a first dielectric layer which is in contact with the metal reflector and formed thereon and a second dielectric layer which is formed on the first dielectric layer and has a higher refractive index than that of the first dielectric layer to light of an optical image outputted from the converting portion, wherein the converting portion is formed on the dielectric film mirror side.
A scintillator panel for which a scintillator composed of a plurality of needle crystals is formed on a support, the support comprising:
- a metal reflector;
- and
- a dielectric film mirror including at least a first dielectric layer which is in contact with the metal reflector and formed thereon and a second dielectric layer which is formed on the first dielectric layer and has a higher refractive index than that of the first dielectric layer to light emitted from the scintillator, wherein the scintillator is formed on the dielectric film mirror side.
A radiation image sensor comprising:
- a radiation image converting panel for which a converting portion that converts a radiation image to an optical image is formed, of a support including a metal reflector and a dielectric film mirror including at least a first dielectric layer which is in contact with the metal reflector and formed thereon and a second dielectric layer which is formed on the first dielectric layer and has a higher refractive index than that of the first dielectric layer to light of the optical image formed on the first dielectric film layer, on the dielectric film mirror side;
- and
- an image pickup device that converts an optical image outputted from the converting portion to an electrical signal.
