Radiation imaging apparatus having a buffer member in a corner and radiation imaging system

A radiation imaging apparatus comprising:

• a radiation detection panel;
• a housing configured to accommodate the radiation detection panel;
• and
• a buffer member, wherein
• the housing has an opening in a corner,
• the buffer member includes a first portion present inside the housing and a second portion protruding from the opening of the housing to an outside of the housing,
• an elastic modulus of the second portion of the buffer member is lower than an elastic modulus of a portion of the housing which forms the opening, and
• the first portion of the buffer member is disposed on an inner surface of the housing with a frame shape so as to surround the radiation detection panel.

A radiation imaging system comprising:

• a radiation imaging apparatus;
• and
• a signal processing unit for processing a signal obtained by the radiation imaging apparatus,
• wherein the radiation imaging apparatus comprises:
• a radiation detection panel;
• a housing configured to accommodate the radiation detection panel, said housing providing an incident plane that is irradiated with radiation, a reversed surface opposite to the incident plane and a side surface connecting the incident plane and the reversed surface;
• and
• a buffer member, wherein
• the housing has an opening in a corner, said opening being formed at the side surface, and
• the buffer member includes a first portion fixed inside the housing and a second portion protruding from the opening of the housing to an outside of the housing.
