Description

  The present invention relates to a radiographic imaging system that acquires radiographic image information of a subject using an imaging apparatus.

  For example, in a medical institution such as a hospital, in order to acquire desired radiation image information of a patient, using RIS (Radiology Information System), patient information such as a patient's name, sex, age, imaging method, imaging site, The doctor sets imaging conditions such as exposure conditions to determine the imaging device to be used and the radiation dose to irradiate the corresponding imaging site, and supplies this information to the console installed in the radiology department, while on-site The technician operates the console to control the specified imaging device according to the exposure conditions to acquire the radiation image information of the patient, and after performing predetermined image processing on the acquired radiation image information, the radiation image information A radiographic imaging system has been constructed that supplies the image data to a viewer that performs interpretation diagnosis by a doctor.

  Here, when performing imaging, an on-site engineer adjusts the position of the imaging region with respect to the imaging device in accordance with the set imaging conditions, and then operates the exposure switch to perform imaging. Radiation image information acquired by imaging is displayed on the console. The engineer confirms the displayed radiographic image information, and changes the imaging conditions such as the imaging region and the exposure conditions as necessary, and performs imaging again.

  In this case, the engineer must move to the console in order to confirm the radiation image information. When performing re-photographing, it becomes necessary to move between the photographing device and the console each time, which is very troublesome. Thus, as a conventional technique capable of avoiding such annoyance, for example, there is one disclosed in Patent Document 1.

  This prior art relates to a mobile X-ray apparatus configured to be movable by placing an X-ray generation unit and a control unit on a mobile carriage, and a flat panel detector connected to the control unit is used as an imaging region of a patient. After setting, radiographic image information is captured by irradiating the patient with X-rays from the X-ray generator. In addition to an imaging area for capturing radiographic image information, the flat panel detector is provided with a display unit for displaying captured radiographic image information and an operation unit for setting imaging conditions.

  The engineer can confirm the radiation image information displayed on the display unit of the flat panel detector on the spot and determine whether or not re-imaging is necessary. In addition, if necessary, the imaging condition can be changed using the operation unit of the flat panel detector, and re-imaging can be performed. By configuring the flat panel detector in this way, the engineer can check the radiation image information and change the imaging conditions without returning to the moving carriage.

JP 2006-334160 A

  However, since the flat panel detector for detecting radiation image information is provided with a display unit and an operation unit, the effective range of the imaging area is limited, or the flat panel detector must be made large in order to avoid this limitation. There is a problem of not becoming.

  Further, when confirming the radiographic image information taken on the display unit, the flat panel detector must be once separated from the imaging region of the patient so that the display unit is not hidden by the patient's body. In this case, for example, even if re-imaging is performed while changing the imaging conditions, it is difficult to accurately arrange the flat detector at the same imaging region, and in order to re-arrange the flat detector, the patient Will be burdened.

  On the other hand, when radiographic image information is imaged, an engineer must retreat to a position away from the X-ray generation unit and perform imaging without being exposed to X-rays. Therefore, even if a flat panel detector is provided with a display unit and operation unit, it is only possible to check radiation image information and set imaging conditions with the flat panel detector, which greatly improves the troublesomeness of these operations. It is not possible.

  The radiographic image capturing system 10 of the present embodiment is basically configured as described above, and the operation thereof will be described next.

  First, patient information such as a patient's name, sex, and age is set using the HIS 12, and then, a doctor relates to the patient information, a radiographic imaging method, an imaging site, and an imaging device used for imaging Imaging conditions including exposure conditions such as tube voltage, tube current, and radiation exposure time for the radiation source constituting the imaging apparatus are set using the RIS 14. The imaging instruction information set by the HIS 12 and the RIS 14 is transmitted to the console 18 installed in the radiology processing room 132 via the in-hospital network 34. The console 18 displays the transmitted shooting instruction information on the display unit 122.

  On the other hand, the engineer waiting in the processing chamber 132 checks the shooting instruction information displayed on the display unit 122 of the console 18 and changes or sets the shooting condition using the shooting condition setting unit 116 as necessary. Do. For example, when the imaging apparatus selected by the doctor is in use or under maintenance, the engineer changes the imaging apparatus to a usable imaging apparatus using the imaging condition setting unit 116. In addition, imaging conditions such as tube voltage, tube current, and radiation exposure time are changed and set according to the imaging region of the subject 36.

  Next, the engineer uses the console 18 to start photographing processing for the subject 36. The engineer selects the subject 36 from the shooting instruction information displayed on the display unit 122 of the console 18, and enters the shooting rooms 138 a to 138 d in which shooting devices based on the shooting conditions set for the subject 36 are installed. The subject 36 is guided. For example, when the photographing room 138a is selected, the subject 36 enters the photographing room 138a through the door 144a and changes clothes in the changing room 146a. The engineer enters the imaging room 138 a from the processing chamber 132 through the door 142 a, adjusts the position of the imaging table 38 of the imaging apparatus 20, adjusts the imaging posture of the subject 36, and then exits to the processing chamber 132. .

  On the other hand, when the imaging room 138 a is selected, the control unit 118 of the console 18 transmits the imaging conditions related to the selected subject 36 to the radiation source control unit 40 and the operation unit 28 of the imaging apparatus 20. In the radiation source control unit 40, exposure conditions such as tube voltage, tube current, and radiation exposure time for the radiation source 24 are set based on imaging conditions. Further, as shown in FIG. 7, the display unit 130 of the operation unit 28 displays the patient name, the photographer, the photographing date and time, etc., based on the photographing conditions, as well as the photographing part information, the tube voltage, and the photographing menu. The exposure conditions such as the tube current and the radiation exposure time are displayed.

  Here, the operation unit 28 includes a setting unit 126, and the engineer can change or reset the imaging conditions using the setting unit 126. The changed and reset imaging conditions are transmitted from the operation unit 28 to the radiation source control unit 40 of the imaging apparatus 20 for adjustment. The imaging conditions changed and reset by the operation unit 28 are transmitted to the console 18 via the in-hospital network 34, and then the imaging conditions set by the operation unit 28 are changed.

  In addition, in the display unit 130 of the operation unit 28, the standard imaging conditions set by the RIS 14 and the like and the imaging conditions changed by the technician, for example, the body thickness of the subject 36, whether or not the child is a pregnant woman By displaying the difference from the shooting condition such as whether or not the shooting condition is changed, it is possible to objectively determine whether the technician changes the shooting condition. Further, when the subject 36 is a pregnant woman, an alarm display or an alarm sound may be issued regarding the shooting conditions.

  After confirming the imaging conditions displayed on the display unit 130 of the operation unit 28, the engineer starts imaging radiographic image information. When the technician depresses the exposure switch 128 of the operation unit 28, an exposure signal is supplied to the radiation source 24 via the radiation source control unit 40. The radiation source 24 supplied with the exposure signal outputs radiation controlled according to the exposure conditions set in the radiation source control unit 40 and irradiates the subject 36.

  The radiation that has passed through the subject 36 is applied to the radiation conversion panel D accommodated in the imaging table 38, and the radiation image information is recorded.

  The photoelectric conversion layer 42 of each pixel 48 constituting the radiation conversion panel D (FIG. 3) converts the incident radiation into an electrical signal, and the electrical signal is held in the storage capacitor 46 as an electric charge. Next, the charge information that is the radiation image information of the subject 36 held in each storage capacitor 46 is read according to the address signal supplied from the control unit 60 to the line scan driving unit 54 and the multiplexer 56.

  That is, the address decoder 58 of the line scanning drive unit 54 outputs a selection signal according to the address signal supplied from the control unit 60 to select one of the switches SW1, and the gate of the TFT 44 connected to the corresponding gate line 50. Is supplied with a control signal Von. On the other hand, the address decoder 66 of the multiplexer 56 outputs a selection signal in accordance with the address signal supplied from the control unit 60 to sequentially switch the switch SW2, and each pixel connected to the gate line 50 selected by the line scan driving unit 54. Radiation image information that is charge information held in the storage capacitors 46 of 48 is sequentially read out via the signal line 52.

  The radiation image information read from the storage capacitor 46 of each pixel 48 connected to the selected gate line 50 of the radiation conversion panel D is amplified by each amplifier 62 and then sampled by each sample and hold circuit 64. The signal is supplied to the A / D converter 68 via the multiplexer 56 and converted into a digital signal. The radiographic image information converted into the digital signal is transmitted by the control unit 60 to the console 18 and the operation unit 28 via the in-hospital network 34.

  Similarly, the address decoder 58 of the line scan driving unit 54 sequentially switches the switch SW1 according to the address signal supplied from the control unit 60, and is held in the storage capacitor 46 of each pixel 48 connected to each gate line 50. The radiographic image information as the charge information is read out via the signal line 52 and transmitted to the console 18 and the operation unit 28 via the multiplexer 56, the A / D converter 68 and the control unit 60.

  The operation unit 28 causes the display unit 130 to display the received radiation image information. In this case, the technician operates the exposure switch 128 of the operation unit 28 to capture the radiation image information, and the photographed subject 36 is displayed on the display unit 130 of the operation unit 28 without moving to the console 18. A preview image of the radiation image information can be confirmed. Note that the preview image only needs to have a resolution that allows the shooting conditions to be confirmed.

  When confirming the preview image and determining that the acquired radiation image information is inappropriate, the engineer changes the imaging condition on the spot using the setting unit 126 of the operation unit 28. In this case, if there is no need to change the imaging posture or the imaging region, re-imaging can be performed immediately by operating the exposure switch 128 without bothering the subject 36. Similarly, the radiation image information acquired by re-imaging can be displayed on the display unit 130 of the operation unit 28 and confirmed again.

  In addition, when displaying the re-imaged radiographic image information on the display unit 130, the radiographic image information acquired by changing the imaging conditions can be obtained by simultaneously displaying the radiographic image information and the imaging conditions acquired in the previous imaging. It is possible to more accurately determine whether or not is appropriate.

  When the acquired radiographic image information is appropriate, the radiographic image information is transmitted from the imaging device 20 or the operation unit 28 to the console 18, and after desired image processing is performed by the image processing unit 120, the in-hospital network 34 is transmitted. Via the viewer 16. The doctor performs necessary interpretation diagnosis based on the radiation image information transmitted to the viewer 16.

  Next, a case where the photographing room 138b is selected will be described.

  On the display unit 130 of the operation unit 30 connected to the imaging device 22 in the imaging room 138b, the imaging conditions related to the selected subject 36 are displayed as in the case of the operation unit 28.

  Next, after the cassette 74 is loaded into the slot 76 of the imaging device 22, the exposure switch 128 of the operation unit 30 is pressed to output radiation from the radiation source 26 and irradiate the subject 36.

  The radiation transmitted through the subject 36 is applied to the radiation conversion panel P accommodated in the cassette 74, and the radiation image information of the subject 36 is accumulated and recorded.

  The cassette 74 that houses the radiation conversion panel P in which the radiation image information is recorded is extracted from the imaging device 22 and then loaded into the cassette loading unit 86 of the reading device 32. When the cassette 74 is loaded, the barcode reader 88 disposed in the cassette loading section 86 reads the barcode 80 mounted on the cassette 74, and identification information such as a unique number, size, sensitivity, etc. of the radiation conversion panel P. To get. The acquired identification information is collated with the identification information acquired by the barcode reader 82 connected to the console 18 to confirm the correspondence between the subject 36 and the radiation image information.

  When the identification information is read, the lock release mechanism 90 is driven, the locked state of the lid member 78 is released, and the lid is opened. Next, the suction disk 92 sucks the radiation conversion panel P, takes out the radiation conversion panel P from the cassette 74, and supplies it between the nip rollers 94. The radiation conversion panel P sandwiched by the nip rollers 94 is transported to the lower portion of the scanning unit 106 via a curved transport path 98 including transport rollers 94a to 94g and guide plates 96a to 96f.

  The radiation conversion panel P is sub-scanned and conveyed in the substantially horizontal direction by the conveying rollers 94d and 94e. On the other hand, the laser beam LB output from the excitation unit 108 is guided to the radiation conversion panel P supported by the platen roller 104 and performs main scanning on the radiation conversion panel P.

  The radiation conversion panel P is excited by being irradiated with the laser beam LB, and outputs the stimulated emission light corresponding to the stored and recorded radiation image information. This stimulated emission light is incident from the lower end of the condensing guide 112 disposed close to the radiation conversion panel P in the main scanning direction, is repeatedly reflected inside, and is guided to the photomultiplier 114 at the upper end. The photomultiplier 114 converts the incident stimulated emission light into an electrical signal, and thereby the radiation image information stored and recorded in the radiation conversion panel P is read.

  The radiation image information read by the scanning unit 106 is transmitted to the console 18 and the operation unit 30 via the hospital network 34.
