RADIOGRAPHIC APPARATUS AND RADIOGRAPHIC SYSTEM |
摘要 |
A radiographic apparatus includes a first grating unit, a grating pattern unit, a radiological image detector. The first grating unit has a plurality of radiation shield units that shields the radiation emitted from the radiation source and a substrate on which the first radiation shield units are arranged and which enables the radiation emitted from the radiation source to penetrate therethrough. The grating pattern unit has a period that substantially coincides with a pattern period of a radiological image. The radiological image detector detects the radiological image masked by the grating pattern unit and has a plurality of pixels converting and accumulating the radiation into charges and a substrate. A thermal expansion coefficient of the substrate of the first grating unit is the substantially same as a thermal expansion coefficient of the substrate of the radiological image detector.
