Abstract

A radiation detection device includes: a radiation detection panel; a supporting member having a first surface and a second surface being opposite to the first surface, wherein the radiation detection panel is provided at a side of the first surface; an electronic component that is provided on the second surface of the supporting member and drives the radiation detection panel or processes an electric signal output from the radiation detection panel; and a housing that accommodates the radiation detection panel, the supporting member, and the electronic component, a bottom of the housing which faces the second surface comprises a flat portion and a slope portion that is adjacent to the flat portion and becomes closer to the second surface as becoming further away from the flat portion, and the electronic component is provided at a position as defined herein.

Claims (44)

1. A radiation detection device comprising:

a radiation detection panel;

a supporting member having a first surface and a second surface being opposite to the first surface, wherein the radiation detection panel is provided at a side of the first surface;

an electronic component that is provided on the second surface of the supporting member and drives the radiation detection panel or processes an electric signal output from the radiation detection panel; and

a housing that accommodates the radiation detection panel, the supporting member, and the electronic component,

wherein a bottom of the housing which faces the second surface comprises a flat portion and a slope portion that is adjacent to the flat portion and becomes closer to the second surface as becoming further away from the flat portion,

the electronic component does not contact with the flat portion, and

the electronic component contacts with the slope portion through a thermal conductor having a viscosity.

2. The radiation detection device according to claim 1 ,

wherein the slope portion comprises a portion that is provided between a boundary between the flat portion and the slope portion and a part of the slope portion that overlaps a center of gravity of the electronic component when viewed in a direction perpendicular to the second surface and is thinner than the flat portion.

3. The radiation detection device according to claim 2 ,

wherein the slope portion is softer than the flat portion.

4. The radiation detection device according to claim 2 ,

wherein the electronic component is provided at a position where at least a part of the electronic component overlaps the slope portion when viewed in the direction perpendicular to the second surface.

5. The radiation detection device according to claim 2 , which further comprises a power supply unit for supplying an electronic power to the radiation detection panel so that the power supply unit is accommodated in the housing.

6. The radiation detection device according to claim 2 ,

wherein the thermal conductor is a gel in which metal particles or metal oxide particles are dispersed.

7. The radiation detection device according to claim 6 ,

wherein the metal particles are aluminum particles, copper particles or silver particles, and the metal oxide particles are alumina particles or magnesium oxide particles.

8. The radiation detection device according to claim 1 ,

wherein the flat portion comprises a rib that protrudes toward the second surface, and

the rib is provided so as to be opposite to a center of gravity of the electronic component with the boundary between the flat portion and the slope portion interposed therebetween.

9. The radiation detection device according to claim 8 ,

wherein the rib extends along the boundary between the flat portion and the slope portion.

10. The radiation detection device according to claim 9 ,

wherein the rib is formed in a ring shape around an outer periphery of the flat portion.

11. The radiation detection device according to claim 10 ,
