Abstract: There is provided a radiation imaging system including a radiation emitting apparatus 3 having a radiation source 34 that generates radiation, a radiation imaging apparatus 100B that receives radiation and generates radiation image data, and a hardware processor. The hardware processor detects height of the radiation source 34 and height of the radiation imaging apparatus 100B. The hardware processor further calculates a distance from a focal point of the radiation generated by the radiation source 34 to the radiation imaging apparatus 100B based on the height of the radiation source 34 and the height of the radiation imaging apparatus 100B, and causes a display to display the calculated distance.

Abstract: An X-ray image capturing apparatus includes: scanning and signal lines; an X-ray sensor; detecting elements; a switching element to make charges accumulated in response to an OFF voltage and released in response to an ON voltage; a scan driving unit to switch a voltage applied to the scanning lines between ON and OFF voltages; a readout circuit to read the charges as image data; and a control circuit to detect an irradiation start by a first scheme based on a current increase due to X-ray irradiation or a second scheme based on an output from the X-ray sensor and to turn off the switching element to make charges accumulated if the first or second scheme detects the irradiation start, wherein a detection threshold is set such that the second scheme has a slower response and can detect an X-ray at a lower dose rate than the first scheme.
