X-Ray Imaging Apparatus |
| 摘要 |
An X-ray imaging apparatus includes: a plurality of detecting elements arranged two-dimensionally; a radiation sensor configured to change a voltage value to be output when radiation is emitted; a determining unit configured to determine whether radiation that has entered the radiation sensor is natural radiation based on a length of a period during which the voltage value output from the radiation sensor is outside a predetermined range set for the voltage value; and an emission start detecting unit configured to determine whether X-ray emission from an X-ray generator has been started based on a determination result indicating that the determining unit has determined that the radiation having entered the radiation sensor is not natural radiation. |

1. An X-ray imaging apparatus comprising:
a plurality of detecting elements arranged two-dimensionally; a radiation sensor configured to change a voltage value to be output when radiation is emitted; a determining unit configured to determine whether radiation that has entered the radiation sensor is natural radiation based on a length of a period during which the voltage value output from the radiation sensor is outside a predetermined range set for the voltage value; and an emission start detecting unit configured to determine whether X-ray emission from an X-ray generator has been started based on a determination result indicating that the determining unit has determined that the radiation having entered the radiation sensor is not natural radiation. |
