RADIATION IMAGING SYSTEM
First Claim
1. A radiation imaging system comprising:
- a portable radiation imaging device including;
a plurality of scan lines;
a plurality of signal lines disposed to intersect with the scan lines;
a plurality of radiation detection elements two-dimensionally disposed in small regions formed by the scan lines and the signal lines;
a scan driving unit which applies ON voltage or OFF voltage to the scan lines;
a plurality of switch elements which are connected to the scan lines and release electric charges accumulated in the radiation detection elements to the signal lines when the ON voltage is applied;
a readout circuit which converts the electric charges released from the radiation detection elements to image data and reads out the image data;
a control unit; and
a communication unit with which the image data is transmitted to an external device;
a radiation generating device which controls a radiation source to irradiate the radiation imaging device;
a console which generates a preview image and a radiation image on the basis of the image data received from the radiation imaging device; and
a portable terminal which transmits a completion signal to the console when the portable terminal receives an input of information indicating that positioning of the radiation imaging device has been completed,wherein the control unit of the radiation imaging device detects whether irradiation has started;
wherein, when the control unit of the radiation imaging device detects the start of irradiation, the control unit changes to an electric charge accumulation state and then allows the image data to be read out from the radiation detection elements to transmit part of the read-out image data to the console as data for preview image, the electric charge accumulation state being a state in which the scan driving unit applies the OFF voltage to the scan lines to accumulate electric charges generated due to the irradiation in the radiation detection elements;
wherein, when the console receives the data for preview image from the radiation imaging device before receiving the completion signal from the portable terminal, the console transmits a cancel signal to the radiation imaging device, stops a process which is being performed by the radiation imaging device, and makes the control unit resume the detection of whether irradiation has started; and
wherein, when the console receives the data for preview image from the radiation imaging device after receiving the completion signal from the portable terminal, the console generates the preview image on the basis of the data for preview image.

Abstract
A radiation imaging system includes a portable radiation imaging device, a radiation generating device, a console and a portable terminal. When the console receives data for preview image from the radiation imaging device before receiving a completion signal from the portable terminal the console transmits a cancel signal to the radiation imaging device, stops a process which is being performed by the radiation imaging device, and makes the radiation imaging device resume detection of whether irradiation has started. When the console receives the data for preview image from the radiation imaging device after receiving the completion signal from the portable terminal, the console generates a preview image on the basis of the data for preview image.
