The radiation image conversion panel in accordance with the present invention has an aluminum substrate; an alumite layer formed on a surface of the aluminum substrate; a metal film, provided on the alumite layer, having a radiation transparency and a light reflectivity; a protective film covering the metal film and having a radiation transparency and a light transparency; and a converting part provided on the protective film and adapted to convert a radiation image.

Radiation image conversion panel, scintillator panel, and radiation image sensor

An Ag film as a light-reflecting film is formed on one surface of an a-C substrate of a scintillator panel. The entire surface of the Ag film is covered with an SiN film for protecting the Ag film. A scintillator having a columnar structure, which converts an incident radiation into visible light, is formed on the surface of the SiN film. The scintillator is covered with a polyparaxylylene film together with the substrate.

Scintillator panel and radiation image sensor

A scintillator elementhas a rod-like base material, and a scintillatoris formed by being vapor deposited radially onto a side face of the base material. A plurality of these scintillator elementsare aligned and bundled together to form a scintillator unit. By mounting a solid-state image pickup elementto an open face of a caseof the scintillator unit, an image sensor M, which serves as a radiation detector, is formed. The image sensor M can be adjusted in size by adjusting the number, etc., of the scintillator elements

An auxiliary substrateis overlapped onto a thin substrate, and substrateand auxiliary substrateare covered with an organic film. Thereafter, a scintillatoris formed on a scintillator forming portionA of organic filmthat corresponds to substrate. Here, since thickness is added to substrateby auxiliary substrate, the warping of substrateis prevented and scintillatoris formed uniformly.

Scintillator panel and method of manufacturing radiation image sensor

The radiation image conversion panel in accordance with the present invention has an aluminum substrate; an alumite layer formed on a surface of the aluminum substrate; a chromium layer covering the alumite layer; a metal film, provided on the chromium layer, having a radiation transparency and a light reflectivity; an oxide layer covering the metal film and having a radiation transparency and a light transparency; a protective film covering the oxide layer and having a radiation transparency and a light transparency; and a converting part provided on the protective film and adapted to convert a radiation image.

An image sensor assembly is mounted and fixed on a mount substrate with an adhesive, and a light sensitive portion of the image sensor assembly is located so as to reach the vicinity of at least one peripheral region. A moisture-proof protective film to cover a scintillator layer of the image sensor assembly is laid so as to cover the scintillator layer over a side wall to which the light sensitive portion is in proximity, up to the back side of a substrate of the image sensor assembly, and this portion on the back side is sandwiched between the image sensor assembly and the mount substrate so as to be fixed.

Radiation image sensor and making method of same

A radiation image sensor comprises (1) an image sensorhaving a plurality of light receiving elements arranged one or two dimensionally, (2) scintillatorhaving columnar structure formed on the light-receiving surface of this image sensorto convert radiation into light including wavelengths that can be detected by the image sensor, (3) a protective filmformed so as to cover and adhere to the columnar structure of the scintillator, and (4) a radiation-transmittable reflective platethat has a reflective surfacedisposed to face the image sensor across the protective film
