Radiation imaging apparatus, system and method as well as program |
摘要 |
An object hereof is to restrain occurrence of artifact in an acquired radiation image with comparatively simple configuration without providing wiring between a radiation source and a radiation imaging apparatus to thereby obtain a radiation image with extremely good quality. Therefore, a controller selectively carries out real read operation of reading an electric signal obtained by activating a drive circuit from a signal processing circuit unit in case of detecting X-ray irradiation with an X-ray detecting circuit and dummy read operation of reading an electric signal obtained by activating a drive circuit from a signal processing circuit unit in case of detecting X-ray non-irradiation with an X-ray detecting circuit; discontinues the dummy read operation at the time of detecting the start of X-ray irradiation with the X-ray detecting unit in dummy read operation; and starts real read operation at the time of detecting the finish of X-ray irradiation with the X-ray detecting unit.
