Two dimensional image pick-up apparatus
An image pickup apparatus for X-ray photography is structurally adapted to absorb external impacts and possible resultant deformations such as deflections of the cabinet so that the interior is protected against damage and remains intact if the cabinet is deformed by the external load. The two-dimensional image pickup apparatus comprises a substrate, two-dimensional photoelectric converters formed on the substrate and an apparatus cabinet containing the substrate and the photoelectric converters in the inside, at least part of the apparatus cabinet being deformable and capable of restore the original profile or a plurality of containers such as air bags being inserted into the gap between said substrate and said apparatus cabinet to prevent the inner wall surface of said apparatus cabinet and said substrate from contacting each other.
1. A radiation detecting device including a two-dimensional image pickup apparatus comprising:
an apparatus cabinet;
a two-dimensional photoelectric converter unit contained in said apparatus cabinet; and
a shock absorber,
wherein said two-dimensional photoelectric converter unit comprises a substrate member, a light-receiving surface, a fluorescent member, and a circuit board,
wherein said light-receiving surface comprises a plurality of photoelectric converters formed on said substrate member,
wherein said fluorescent member is arranged between said light-receiving surface and said apparatus cabinet,
wherein said circuit board is electrically connected to said plurality of photoelectric converters and is arranged at a surface of said substrate member opposite to said light-receiving surface,
wherein said shock absorber comprises at least a first container and a second container, and
wherein the first container is arranged between said fluorescent member and said apparatus cabinet, and the second container is arranged between said circuit board and said apparatus cabinet.
2. A radiation detecting device according to claim 1 , wherein said first container overlies the entire surface of said fluorescent member.
3. A radiation detecting apparatus comprising:
an apparatus cabinet;
a photoelectric converter unit contained in said apparatus cabinet; and
a shock absorber,
wherein said photoelectric converter unit comprises a substrate, a plurality of photoelectric converters formed on said substrate, a fluorescent member arranged at a light-receiving surface of said photoelectric converter unit, and a circuit board electrically connected to said plurality of photoelectric converters and arranged at a surface of said substrate opposite to said light-receiving surface,
wherein the shock absorber comprises at least a first container and a second container, and
wherein the first container is arranged between said fluorescent member and said apparatus cabinet, and the second container is arranged between said circuit board and said apparatus cabinet.
4. A radiation detecting apparatus according to claim 3 , wherein each of said first and second containers comprises one or more containers.
5. A radiation detecting apparatus according to claim 4 , wherein each of the one or more containers of the first and second containers contains a gas in a sealed state.
6. A radiation detecting apparatus according to claim 5 , wherein each of the one or more containers of the first and second containers are air bags.
7. A radiation detecting apparatus according to claim 3 , wherein
said circuit board has electronic parts, and said second container is held in contact with the electronic parts of said circuit board for cooling of said electronic parts.
8. A radiation detecting apparatus according to claim 7 , wherein said second container comprises one or more containers containing a cooling liquid therein.
9. A radiation detecting apparatus according to claim 3 , wherein said first or second container contains a gelled material.
10. A radiation detecting apparatus according to claim 3 , wherein said first container overlies the entire surface of said fluorescent member.
