Is stored and configured.

  As shown in the figure, in the present embodiment, the state of transmission of image data indicating one radiation image from the electronic cassette 32 to the console 42 is completed as the state type related to radiographic image capturing. "Transmission of one image" and transmission of image data indicating radiographic images corresponding to the number of radiographs input on the initial information input screen (see also FIG. 7) to be described later from the electronic cassette 32 to the console 42 are terminated. “End of transmission of all images”, which is in a state of being performed, “Warning occurrence” in which a warning has occurred in the electronic cassette 32, and “Error occurrence” in which an error has occurred in the electronic cassette 32 are applied. . In the example illustrated in FIG. 5, for example, when the state related to radiographic image capturing is “one image transmission completed”, a sound (presence of this embodiment) is determined by the speaker 144 of the mobile terminal device 140 by the notification function. In the embodiment, a buzzer sound) is intermittently sounded for 1 second, while vibration by the vibrator 145 is not performed.

  As shown in FIG. 5, in the imaging system 18 according to the present embodiment, the state to be notified is notified by a combination of sound and vibration, and the state regarding the radiographic image capturing is set as the notification sound pattern and the notification vibration pattern. Since different types are applied for each type, the photographer can easily grasp the state related to the radiographic image capturing without moving the line of sight to the mobile terminal device 140. .

  Further, in order to realize the notification function, the ROM 106 of the console 42 stores end information indicating that transmission of image data indicating one radiation image from the electronic cassette 32 to the console 42 is completed, and the electronic cassette 32. All end information indicating that transmission of image data indicating radiographic images corresponding to the number of radiographs input on the initial information input screen described later from the console to the console 42 has been stored in advance.

  Next, the operation of the imaging system 18 according to the present embodiment will be described.

  First, with reference to FIG. 6, the operation of the console 42 when radiographic images are taken will be described. FIG. 6 is a flowchart showing a flow of processing of a radiographic image capturing processing program executed by the CPU 104 of the console 42 when an instruction operation to be executed by the operator of the console 42 is performed via the operation panel 102. The program is stored in a predetermined area of the ROM 106 in advance.

  In step 300 in the figure, the display driver 112 is controlled so that a predetermined initial information input screen is displayed on the display 100, and in step 302, input of predetermined information is waited.

  FIG. 7 shows an example of an initial information input screen displayed on the display 100 by the processing in step 300 described above. As shown in the figure, in the initial information input screen according to the present embodiment, the name of the subject who is going to capture a radiographic image, the region to be imaged, and the posture at the time of capturing (in this embodiment, lying down, standing A message for prompting the user to input the number of shots, the number of shots, and the exposure condition of the radiation X at the time of shooting (in this embodiment, the tube voltage, the tube current, and the exposure period when the radiation X is exposed). Then, an input area for such information is displayed.

  When the initial information input screen shown in the figure is displayed on the display 100, the operator of the console 42 determines the name of the subject to be imaged, the imaging region, the posture at the time of imaging, the number of images, and the exposure conditions. , Input to the corresponding input areas via the operation panel 102. On the other hand, a photographer who captures a radiographic image has the portable terminal device 140, and holds the electronic cassette 32 used for imaging according to the planned imaging posture, the holding unit 150 of the standing platform 45 or the prone position platform 46. Is held by the holding unit 152, and the subject is on standby in a state where the subject is positioned at a predetermined imaging position. When the operator of the console 42 confirms that the above-described work by the photographer has been completed, the operator designates an end button displayed near the lower end of the initial information input screen via the operation panel 102.

  When the operator designates the end button of the initial information input screen, step 302 is affirmative and the process proceeds to step 304, and the number of shots input on the initial information input screen is substituted for the remaining number of shots (variable). To do.

  In the next step 306, the exposure condition input on the initial information input screen is transmitted to the radiation generator 34 and the electronic cassette 32 via the wireless communication unit 118, thereby setting the explosion condition. 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 308, 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 conditions 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, The gate line driver 80 is controlled after the exposure period specified by the above exposure conditions, and the gate line driver 80 sequentially outputs an ON signal to each gate line 76 one line at a time. Each TFT 70 is turned on one line at a time.

By doing so, the mobile presentation information is created.

  In the next step 438, the mobile presentation information created by the processing in step 436 is transmitted to the mobile terminal device 140 via the wireless communication unit 118, and then the second information transmission processing routine program is terminated. When the second information transmission processing routine program ends, the process proceeds to step 308 of the radiographic image capturing processing program (main routine).

  On the other hand, if the determination in step 324 is affirmative, the process proceeds to step 328 to execute the third information transmission processing routine / program.

  Hereinafter, the third information transmission processing routine program according to the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart showing the flow of processing of the third information transmission processing routine program. This program is also stored in a predetermined area of the ROM 106 in advance.

It is a flowchart, and the program is stored in advance in a predetermined area of the memory 141A built in the terminal control unit 141.

  In step 500 of the figure, it is determined whether or not the information received from the console 42 is end information. If the determination is affirmative, the process proceeds to step 502.

  In step 502, a notification sound pattern corresponding to “end of one image transmission” in the notification pattern information is read from the memory 141A, and in the next step 504, the speaker 144 is operated so as to operate in a state corresponding to the read notification sound pattern. After the control, the notification processing program is terminated.

  On the other hand, if a negative determination is made in step 500, the process proceeds to step 506, and it is determined whether the information received from the console 42 is portable presentation information. If the determination is affirmative, the process proceeds to step 508. To do.

  In step 508, it is determined whether warning information is included in the received mobile presentation information. If the determination is negative, the process proceeds to step 514. If the determination is affirmative, the process proceeds to step 510. .

  In step 510, a notification vibration pattern corresponding to “warning occurrence” in the notification pattern information is read from the memory 141A, and in the next step 512, the vibrator 145 is controlled to vibrate in a state corresponding to the read notification vibration pattern. The process proceeds to step 514 later.

  In step 514, it is determined whether or not error information is included in the received mobile presentation information. If the determination is negative, the process proceeds to step 520. If the determination is affirmative, the process proceeds to step 516. .

  In step 516, a notification sound pattern corresponding to “error occurrence” in the notification pattern information is read from the memory 141A, and in step 518, the speaker 144 is controlled to operate in a state corresponding to the read notification sound pattern. The process proceeds to step 520 later.

  In step 520, based on the remaining power amount information included in the mobile presentation information, the number of images that can be captured by the electronic cassette 32 at the remaining power amount indicated by the remaining power amount information is derived. In portable terminal device 140 according to the present embodiment, the number of shootable images is derived by referring to table information indicating the relationship between a predetermined remaining power amount and the number of shootable images. The present invention is not limited to this, and it goes without saying that other forms such as, for example, a form derived using a predetermined arithmetic expression as being capable of calculating the number of shootable images by substituting the remaining power amount may be used.

  In the next step 522, display is performed so as to display a shooting-related information notification screen having a predetermined format using the remaining power amount and the number of shootable images and the remaining number of shots included in the mobile presentation information. The unit 143 is controlled, and then the notification processing program is terminated.
