Radiation detection device

摘要

According to one embodiment, a radiation detection device includes a chassis, a radiation detection panel, a support plate and a circuit board. The chassis includes an incident face cover and a side face portion covering a side face perpendicular to the incident face cover. The radiation detection panel is housed inside the chassis and is configured to detect radiation incident through the incident face cover. The support plate is housed inside the chassis and is fixed to the side face portion to support the radiation detection panel on a rear face on an opposite side to an incident face of the radiation. The circuit board is housed inside the chassis and is disposed on an opposite side to the radiation detection panel of the support plate. At least a part of a drive circuit configured to drive the radiation detection panel is mounted on the circuit board.

主权项

1. A radiation detection device, comprising:
a chassis including an incident face cover and a plurality of side face portions including a side face perpendicular to the incident face cover, each of the side face portions including a fixing portion protruding inward in parallel to the incident face cover, and the chassis being substantially a rectangular parallelepiped; a radiation detection panel housed inside the chassis and configured to detect radiation incident through the incident face cover, the radiation detection panel being in a plain plate configuration; a support plate housed inside the chassis and fixed to each fixing portion to support the radiation detection panel, each fixing portion being fixed to the support plate on a rear face of the support plate on an opposite side to an incident face of the radiation; a circuit board housed inside the chassis and disposed on an opposite side to the radiation detection panel of the support plate, at least a part of a drive circuit configured to drive the radiation detection panel being mounted on the circuit board; and a plurality of flexible circuit boards electrically connecting the radiation detection panel and the circuit board, wherein the fixing portions are provided in a plurality of positions without interference with the flexible circuit boards, a planar shape of the support plate is a quadrangle, the fixing portions are provided in a vicinity of each side of the support plate, the fixing portions are provided at a position away from a corner of the support plate, and one of the plurality of the flexible circuit boards is provided in between a pair of the fixing portions.
