Radiation image capturing system and console

A radiation image capturing system comprising:

• a radiation image capturing apparatus including:
• a plurality of scanning lines and a plurality of signal lines, both of the lines arranged to intersect each other;
• a plurality of radiation detection elements arrayed two-dimensionally;
• a scan drive unit which switches a voltage to be applied to the scanning lines between an ON voltage and an OFF voltage;
• switch units connected to the scanning lines, the switch units to discharge electric charge accumulated in the radiation detection elements to the signal lines when the ON voltage is applied;
• a readout circuit which reads out the electric charge discharged to the signal lines;
• and
• a control unit which detects a start of radiation irradiation based on data to be changed by the radiation irradiation, sets a scanning line from which readout of image data is started from timing at a time of the detection, starts application of the ON voltage from the set scanning line to read out the image data, and generates preview image data from the readout image data;
• and
• a console which displays a preview image based on the preview image data transmitted from the radiation image capturing apparatus and information regarding the scanning line from which the readout of the image data is started,
• wherein the console holds in advance a relationship between a number of the scanning line in a case where the radiation image capturing apparatus sets, as a starting point, the scanning line from which readout of the image data is started and an offset amount superimposed on the image data to be read out, and
• when the preview image is displayed, based on the information regarding the scanning line from which the readout of the image data is started, modifies the relationship to a form in which the starting point is moved to a position of the scanning line from which the radiation image capturing apparatus actually starts the readout of the image data, calculates the offset amount for each of the scanning lines, and generates and displays the preview image based on a value obtained by subtracting the offset amount from the corresponding preview image data.
