Problems solved by technology

[0004] However, the technologies disclosed in JP-A-5-196742 and JP-A-5-242841 are not easy to form a moisture-proof structure.
Although the techniques disclosed in International Publication No. WO98 / 36290 and No. 36291 solve this type of problem, they do not seem to have sufficient strength

Abstract

A radiation image sensor comprises an image sensor (1) including a one- or two-dimensional array of photodetector elements (12); needlelike scintillators (2) formed on the photodetector surface of the image sensor (1) and adapted to convert radiation into light of wavelength detectable by the image sensor (1); a protective film (3) formed in close contact over the needlelike scintillators (2); a frame (6) arranged around and away from the scintillators and adapted to fix the protective film onto the image sensor (1); and a radiation-transparent reflector (4) fixed by the frame (6) and opposed to the image sensor across the protective film (3).

Description

technical field [0001] The present invention relates to an image sensor for detecting radiographic images used in medical treatment and the like, and a scintillator panel for converting a radiological image into an optical image detectable by the image sensor. technical background [0002] Medical and industrial X-ray photography has traditionally used X-ray photosensitive film, but in consideration of convenience and preservation of photographic effects, radiation imaging systems using radiation detection elements are becoming popular. In such a radiation imaging system, a radiation detection element having a plurality of pixels is used to obtain two-dimensional image data generated by radiation as an electrical signal, and the signal is processed by a processing device and displayed on a monitor. In a typical radiation detection element, a scintillator is arranged on a one-dimensional or two-dimensional array of photosensors, and the incident radiation is converted into vi...
