Abstract

Disclosed is a radiation image imaging apparatus including: a radiation detector that detects radiation; a hardware processor that controls imaging of a radiation image by driving a readout circuit in a first power consumption mode or a second power consumption mode in which power consumption is larger than in the first power consumption mode; and a housing that houses the radiation detector and the hardware processor. The hardware processor enables imaging in the second power consumption mode in response to the radiation image imaging apparatus being in contact with a heat suppressor and prohibits the imaging in the second power consumption mode or stops driving of the readout circuit in the second power consumption mode after end of the imaging in the second power consumption mode in response to the radiation image imaging apparatus being not in contact with the heat suppressor.

First claim

What is claimed is:

1 . A radiation image imaging apparatus comprising:
a radiation detector that detects radiation; a hardware processor that controls imaging of a radiation image by driving a readout circuit that reads out an image signal from the radiation detector in a first power consumption mode or a second power consumption mode in which power consumption is larger than power consumption in the first power consumption mode; and a housing that houses the radiation detector and the hardware processor, wherein the hardware processor enables imaging in the second power consumption mode in response to the radiation image imaging apparatus being in contact with a heat suppressor that suppresses an increase in a surface temperature of the housing, and prohibits the imaging in the second power consumption mode or stops driving of the readout circuit in the second power consumption mode after end of the imaging in the second power consumption mode in response to the radiation image imaging apparatus being not in contact with the heat suppressor.

2 . The radiation image imaging apparatus according to claim 1 , wherein
the radiation image imaging apparatus includes a first moving image imaging mode and a second moving image imaging mode, and moving image imaging is performed at a same frame rate in the first moving image imaging mode and in the second moving image imaging mode, and the hardware processor drives the readout circuit in the first power consumption mode in the first moving image imaging mode and drives the readout circuit in the second power consumption mode in the second moving image imaging mode.

3 . The radiation image imaging apparatus according to claim 2 , wherein the first moving image imaging mode is a serial imaging mode, and the second moving image imaging mode is a fluoroscopy mode.

4 . The radiation image imaging apparatus according to claim 1 , wherein the heat suppressor is at least one of an air cooling mechanism, a water cooling mechanism, a heat storage material, and a heat transfer material.

5 . The radiation image imaging apparatus according to claim 1 , further comprising:
a temperature detector that detects a temperature of the housing; and a notifier that notifies detection of a temperature that is a predetermined temperature or higher in response to the temperature being detected by the temperature detector.
