Abstract
An X-ray imaging system includes a plurality of electronic cassettes having FPDs. One of the plural electronic cassettes for use in imaging is selected by input operation. Control is performed in a first mode operation being normal for the electronic cassette selected in the selecting step. Control is performed in a second mode operation being auxiliary of which driving power is lower than in the first mode operation for one of the electronic cassettes in an unselected state in the selecting step. Assuming that irradiation of the radiation is detected in the second mode operation, error information is displayed in relation to selecting the electronic cassette in the selecting step. For example, the first and second mode operations are pixel reset in which charge stored in pixels are swept in an FPD.

A radiographic imaging system including a plurality of radiographic image detectors each of which has a sensor panel for detecting a radiographic image according to radiation, and a user input interface for selecting one of said plural radiographic image detectors for use in imaging, said radiographic imaging system comprising:
- a controller, associated with each of said radiographic image detectors, for performing a first mode operation for said radiographic image detector in case a selected state is set according to said user input interface, and performing a second mode operation for said radiographic image detector in case an unselected state is set according to said user input interface, where driving power in said second mode operation is lower than in said first mode operation for detecting irradiation of said radiation;
- and
- a display device for, assuming that irradiation of said radiation is detected in said second mode operation, displaying error information in relation to selecting said radiographic image detector with said user input interface,
- wherein in said first mode operation, said radiographic image detector outputs a dose signal that represents a dose of an incident radiation reaching said sensor panel, and
- wherein in said second mode operation, the output frequency of said dose signal per unit time is lower than that in said first mode operation.
A system operation method for a plurality of radiographic image detectors for detecting a radiographic image, comprising steps of:
- selecting one of said plural radiographic image detectors for use in imaging by input operation;
- performing a first mode operation for said radiographic image detector selected in said selected step;
- performing a second mode operation for one of said radiographic image detectors unselected in said selecting step, where driving power in said second mode operation is lower than in said first mode operation for detecting irradiation of said radiation;
- and
- assuming that irradiation of said radiation is detected in said second mode operation, displaying error information in relation to selecting said radiographic image detector in said selecting step,
- wherein in said first mode operation, said radiographic image detector outputs a dose signal that represents a dose of an incident radiation reaching said sensor panel, and
- wherein in said second mode operation, the output frequency of said dose signal per unit time is lower than that in said first mode operation.
