Abstract: A method of testing waterproof performance of a radiological imaging apparatus including: a sensor panel including a plurality of radiation detecting elements two-dimensionally arranged; a housing containing the sensor panel; and an air pressure measuring unit configured to measure an air pressure in the housing having a vent hole allowing the air to flow into and out of the housing, includes: a load application step of continuing to apply a load to the housing; an air pressure measurement step of measuring the air pressure in the housing with the air pressure measuring unit, the air pressure changing while the load is being applied to the housing; and a waterproof performance determination step of determining whether the waterproof performance of the radiological imaging apparatus is normal based on a pattern of change in the measured air pressure in the housing.

Abstract: Disclosed are a radiation image capturing system and a radiation image capturing apparatus. According to one implementation, the radiation image capturing system includes the radiation image capturing apparatus and a console. The detecting unit of the radiation image capturing apparatus detects start of irradiation using a first detecting method in which power consumption amount is small but a capturing condition with which the start of irradiation can be detected is limited, or a second detecting method in which power consumption amount is large but the start of irradiation can be detected under any capturing condition. The console transmits a capturing condition to the radiation image capturing apparatus. The detecting unit selects the first or second detecting method based on the capturing condition, and performs processing of detecting the start of irradiation using the selected detecting method.

Abstract: A portable radiographic imaging apparatus includes a switching unit that switches power to the apparatus on and off or switches a power consumption mode of the apparatus between imageable mode and power saving mode; an event information managing unit that collects event information about the apparatus or imaging, or accepts input event information; and a storage unit that saves the collected or input event information. The apparatus includes a battery configured to supply power. The switching unit determines whether to perform imaging, based on past event information saved in the storage unit and event information collected or input at present time, and switches the power from on to off or switches the power consumption mode from the imageable mode to the power saving mode, when the switching unit determines that imaging is not performed.
