|1. (WO2018146912) RADIATION IMAGING DEVICE AND IMAGING SYSTEM|
|Applicants:||CANON KABUSHIKI KAISHA
|Title:||RADIATION IMAGING DEVICE AND IMAGING SYSTEM|
The present invention provides a technology that is useful for improving reliability by improving the load resistance of a radiation imaging device configured to be capable of acquiring a radiation image based on energy subtraction processing. This radiation imaging device includes: a first imaging panel including a first sensor substrate having a central region and a peripheral region, and a first scintillator disposed in the central region; a second imaging panel having a second sensor substrate having a central region and a peripheral region, and a second scintillator disposed in the central region, the second imaging panel being disposed above the first imaging panel; a support base that supports the first imaging panel from below; and a support member that is disposed at the lower side of the peripheral region of the second sensor substrate such that a load acting from the upper side on the peripheral region of the second sensor substrate is received by the support base.
