  On the other hand, a photographer who captures a radiographic image holds the electronic cassette 32 used for imaging on the holding unit 150 of the standing table 45 or the holding unit 152 of the prone table 46 in accordance with the planned imaging posture. Wait in state.

  Further, when the electronic cassette 32 receives the subject information and the imaging condition information transmitted from the console 42 in the process of step 304, the electronic cassette 32 executes an information display process to be described later, and displays the received subject information and imaging condition information. The image is displayed on the liquid crystal display panel 64A.

  In response to this, the photographer confirms the information displayed on the liquid crystal display panel 64A, and if there is no particular problem, positions the subject at a predetermined photographing position and then photographs the electronic cassette 32. Preparation completion information indicating that preparation has been completed is transmitted to the console 42.

  Note that the information display processing according to the present embodiment can change the subject information and the imaging condition information displayed by the liquid crystal display panel 64A, and when the change is made, After the change instruction information instructing the same change as the change is transmitted from the electronic cassette 32 to the console 42 together with the information indicating the change contents, the preparation completion information is transmitted. When the preparation completion information is received from the electronic cassette 32, the above step 306 becomes affirmative and the process proceeds to step 308.

  In step 308, it is determined whether or not change instruction information has been received from the electronic cassette 32. If a negative determination is made, the process proceeds to step 314 described later, whereas if an affirmative determination is made, the process proceeds to step 310. .

  In step 310, the subject information and the imaging condition information input on the initial information input screen are changed so as to match the change contents indicated by the information received together with the change instruction information from the electronic cassette 32, and the next step 312 is executed. Then, after transmitting the change end information indicating that the change process according to the change instruction information has ended to the electronic cassette 32 via the wireless communication unit 118, the process proceeds to step 314.

  In step 314, the exposure condition is set by transmitting the exposure condition information input on the initial information input screen to the radiation generator 34 and the electronic cassette 32 via the wireless communication unit 118. In response to this, the radiation source controller 134 of the radiation generator 34 prepares for exposure under the received exposure conditions.

  In the next step 316, instruction information for instructing the start of exposure is transmitted to the radiation generator 34 and the electronic cassette 32 via the wireless communication unit 118.

  In response to this, the radiation source 130 generates and emits radiation at a tube voltage, a tube current, and an exposure period corresponding to the exposure condition information received by the radiation generator 34 from the console 42. The radiation X exposed from the radiation source 130 reaches the electronic cassette 32 after passing through the subject.

  On the other hand, when the cassette control unit 92 of the electronic cassette 32 receives the instruction information instructing the start of exposure, the cassette control unit 92 starts accumulating charges in the storage capacitors 68 of the pixel units 74 of the built-in radiation detector 60, After the elapse of the exposure period specified by the exposure condition information, the gate line driver 80 is controlled to output an ON signal to each gate line 76 one line at a time from the gate line driver 80 and connected to each gate line 76. Each TFT 70 is turned on one line at a time.

  In the radiation detector 60, when the TFTs 70 connected to the gate wirings 76 are sequentially turned on line by line, the charges accumulated in the storage capacitors 68 sequentially line by line flow out to the data wirings 78 as electric signals. The electric signal flowing out to each data wiring 78 is converted into digital image data by the signal processing unit 82 and stored in the image memory 90.

  The cassette control unit 92 transmits the image data stored in the image memory 90 to the console 42 by wireless communication after the end of shooting.

  Therefore, in the next step 318, the process waits until the image data is received from the electronic cassette 32, and in the next step 320, image processing for performing various corrections such as shading correction on the received image data is executed. To do.

  In the next step 322, the image data subjected to the image processing (hereinafter referred to as “corrected image data”) is stored in the HDD 110, and in the next step 324, the radiation image indicated by the corrected image data is stored. The display driver 112 is controlled so as to be displayed on the display 100 for confirmation and the like, and in the next step 326, the corrected image data is sent to the RIS server 14 along with the subject information and the imaging condition information. Then, the radiographic image capturing processing program is terminated. Note that the corrected image data transmitted to the RIS server 14 is stored in the database 14A together with the subject information and the imaging condition information received together with the corrected image data, and the doctor interprets and diagnoses the radiographic image captured by the doctor. It becomes possible.

  Next, the operation of the electronic cassette 32 when executing the information display process will be described with reference to FIG. FIG. 7 is a flowchart showing the flow of processing of the information display processing program executed by the CPU 92A in the cassette control unit 92 of the electronic cassette 32 when the subject information and the imaging condition information are received from the console 42.
