发明名称 Radiological image detection apparatus
摘要 A radiological image detection apparatus includes a radiological image conversion panel and a sensor panel. A sealant that is disposed between a substrate of the radiological image conversion panel and a substrate of the sensor panel and surrounds a scintillator in the radiological image conversion panel and a pixel array in the sensor panel to form an isolated space on the inside of the sealant. The scintillator includes a columnar portion including a group of columnar crystals formed by growing crystals of the phosphor in columnar shapes and a surface configured by a set of tips of the columnar crystals is disposed in close contact with the pixel array without being bonded to the pixel array. Both of the substrate of the radiological image conversion panel and the substrate of the sensor panel are flexible, and the isolated space is depressurized.

主权项 1. A radiological image detection apparatus comprising: a radiological image conversion panel that includes a scintillator including a phosphor that generates fluorescence upon exposure to radiation, and a substrate supporting the scintillator; a sensor panel that includes a pixel array disposed in close contact with the scintillator and detecting the fluorescence generated from the scintillator, and a substrate supporting the pixel array; and a sealant that is disposed between the substrate of the radiological image conversion panel and the substrate of the sensor panel and surrounds the scintillator and the pixel array to form an isolated space on the inside of the sealant, wherein the scintillator includes a columnar portion including a group of columnar crystals formed by growing crystals of the phosphor in columnar shapes, a surface configured by a set of tips of the columnar crystals is disposed in close contact with the pixel array without being bonded to the pixel array, both of the substrate of the radiological image conversion panel and the substrate of the sensor panel are flexible, the isolated space is depressurized, the substrate of the radiological image conversion panel is a first substrate disposed on an opposite side to a radiation incident side, the first substrate includes a plurality of base materials stacked, the base materials including a first base material having a surface on which the scintillator is disposed, and the first base material and another base material except for the first base material among the plurality of base materials are bonded to each other with a dismantlable adhesive of which the bonding strength is reduced by energy irradiation.
