Description

  The present invention relates to a radiographic image capturing system, a radiation converter, and an imaging table that adjust the magnification of radiographic images captured at different magnifications.

  2. Description of the Related Art In the medical field, imaging devices that take a radiation image by irradiating a subject with radiation and guiding the radiation transmitted through the subject to a radiation conversion panel are widely used.

  In this case, as a radiation conversion panel, a stimulable phosphor panel is known in which radiation energy as a radiation image is accumulated in the phosphor and the radiation image can be extracted as stimulated emission light by irradiating excitation light. . The stimulable phosphor panel on which the radiation image is recorded is supplied to a reading device and subjected to reading processing, whereby a radiation image as a visible image can be obtained.

  Further, in a medical field such as an operating room, it is required that the radiation image information can be read and displayed immediately from the radiation conversion panel in order to perform a quick and accurate treatment on the patient. Radiation conversion using a solid-state detector that converts radiation directly into an electrical signal, or converts radiation into visible light with a scintillator and then converts it into an electrical signal and reads it as a radiation conversion panel that can meet such requirements Panels are being developed.

  There are various types of imaging devices that use these radiation conversion panels to capture radiographic images with different specifications according to imaging conditions such as the condition of the patient as the subject and the imaging region. It is controlled by the processing device corresponding to the specification form. These imaging devices and processing devices are connected to a radiology information system (RIS) via an in-hospital network, and the patient information, imaging method, imaging site, imaging conditions that define the radiation dose, etc. set in the RIS are processed. There is a system in which a radiographic image is captured using a corresponding imaging apparatus (see Patent Document 1).

  Using this system, for example, when imaging the site of interest of the same patient regularly and for follow-up observation, it is originally desirable to image with the same imaging device and the same imaging conditions. Depending on the usage status of the imaging device, it may not be possible to capture images with the same imaging device. For example, in the case of a patient who is difficult to walk, the imaging device is different when imaging is performed while lying on a bed and imaging is performed in a standing position when the same patient is able to walk later. In such a case, if the distance between the subject and the radiation conversion panel is different between the radiographic images taken by different imaging devices, the magnification of the obtained radiographic images is different, and the radiographic images are accurately compared with each other as they are. It becomes difficult.

  An apparatus that prepares a normal X-ray source for normal imaging and a small-focus X-ray source for enlarged imaging, and changes the imaging magnification by switching the X-ray source corresponding to the target region of the subject ( Patent Document 2) is known.

In addition, an in-hospital network 24 can be connected to an imaging device of another specification form, for example, a CT device or an MR device, and a console for controlling these imaging devices can be connected.

  The radiographic image capturing system 10 according to the first embodiment of the present invention is basically configured as described above. Next, the operation thereof will be described.

  First, patient information such as a patient's name, sex, and age is set using the HIS 12, and then, in relation to the patient information, a radiographic imaging method, imaging site, imaging apparatus used for imaging, etc. Instruction information is set using the RIS 14.

  The control unit 42 of the console 16 installed in the radiology department acquires patient information and imaging instruction information from the RIS 14 via the in-hospital network 24. The engineer uses the operation setting unit 44 of the console 16 to change and set the shooting instruction information as necessary. For example, the imaging device set by the doctor using the RIS 14 is changed to an imaging device corresponding to the imaging region or the patient's condition. The imaging instruction information setting unit 48 temporarily stores the acquired patient information and imaging instruction information, or changed or newly set imaging instruction information in the imaging instruction information memory 46.

  Next, the imaging instruction information setting unit 48 of the console 16 reads out patient information and imaging instruction information from the imaging instruction information memory 46, and performs radiographic image imaging processing using the specified imaging apparatus according to the imaging instruction information.

  Therefore, first, a case where the first photographing device 18 is controlled using the console 16 to photograph the subject 56 will be described. In the first imaging device 18, the electronic cassette 60 is placed between the imaging table 28 and the subject 56, and close-contact imaging is performed in a state where the subject 56 and the electronic cassette 60 are in close contact.

  The console 16 sets the tube voltage, tube current, and radiation irradiation time, which are the imaging conditions included in the imaging instruction information, to the radiation source control unit 58 of the first imaging device 18.

  Next, after the subject 56 is positioned at a predetermined position of the first photographing device 18, photographing is started by operating an exposure switch (not shown). The radiation source control unit 58 drives and controls the radiation source 26 according to the set imaging conditions, and irradiates the subject 56 with the radiation X. The radiation X that has passed through the subject 56 is applied to the radiation conversion panel 70.

  The photoelectric conversion layer 72 of each pixel 78 constituting the radiation conversion panel 70 (FIG. 4) converts the incident radiation X into an electrical signal, and the electrical signal is held in the storage capacitor 76 as a charge. Next, the charge information that is the radiation image information of the subject 56 held in each storage capacitor 76 is read according to the address signal supplied from the control unit 112 to the line scan driving unit 84 and the multiplexer 86.

  That is, the address decoder 88 of the line scan driving unit 84 outputs a selection signal according to the address signal supplied from the control unit 112 to select one of the switches SW1, and the gate of the TFT 74 connected to the corresponding gate line 80. Is supplied with a control signal Von. On the other hand, the address decoder 96 of the multiplexer 86 outputs a selection signal in accordance with the address signal supplied from the control unit 112 to sequentially switch the switch SW2, and each pixel connected to the gate line 80 selected by the line scan driving unit 84. Radiation image information as charge information held in the storage capacitor 76 of 78 is sequentially read out via the signal line 82.

  The radiation image information read from the storage capacitor 76 of each pixel 78 connected to the selected gate line 80 of the radiation conversion panel 70 is amplified by each amplifier 92 and then sampled by each sample and hold circuit 94. After being supplied to the A / D converter 98 through the multiplexer 86 and converted into a digital signal, it is temporarily stored in the image memory 108. Next, the radiation image information is transmitted to the console 16 from the transmission / reception unit 104 connected to the control unit 112.

  Similarly, the address decoder 88 of the line scan driving unit 84 sequentially switches the switch SW1 according to the address signal supplied from the control unit 112 and is held in the storage capacitor 76 of each pixel 78 connected to each gate line 80. The radiographic image information, which is the charge information, is read through the signal line 82, converted into a digital signal through the multiplexer 86 and the A / D converter 98, and transmitted to the console 16 from the transmission / reception unit 104 connected to the control unit 112. The

  In the console 16, the radiation image information is subjected to image processing by the image processing unit 50, stored in the image memory 52, and then displayed on the display unit 54. The engineer confirms the radiation image information displayed on the display unit 54 and determines, for example, whether or not re-imaging is necessary. If it is determined that the radiographic image information is appropriate, the radiographic image information is transmitted to the RIS 14 via the in-hospital network 24 and used for interpretation diagnosis by a doctor.

  Next, a case where the second imaging device 20 is controlled using the console 16 to perform chest imaging of the same subject 56 will be described.

  First, the electronic cassette 60 is loaded into the slot 34 of the imaging table 32. When the electronic cassette 60 is loaded, the transmission / reception unit 66 of the second imaging device 20 receives a signal oscillated from the transmission / reception unit 104 of the electronic cassette 60. The loading detection unit 62 detects that the electronic cassette 60 is loaded in the slot 34 based on the signal received by the transmission / reception unit 66. When loading of the electronic cassette 60 is detected, the shooting position information stored in the shooting position information memory 64 is transmitted from the transmission / reception unit 66 to the electronic cassette 60 and stored in the shooting position information memory 106.

  Thereafter, similarly to the close-contact imaging by the first imaging device 18 described above, the console 16 instructs the radiation source control unit 58 of the second imaging device 20 to acquire the tube voltage, the tube current, and the imaging conditions included in the imaging instruction information. After setting the irradiation time of the radiation and positioning the subject 56 at a predetermined position of the second imaging device 20, imaging is started by operating an exposure switch (not shown). The radiation source control unit 58 drives and controls the radiation source 30 according to the set imaging conditions, and irradiates the subject 56 with the radiation X. The radiation X that has passed through the subject 56 is applied to the radiation conversion panel 70.

  In the radiation conversion panel 70, the same processing as that of the close contact imaging by the second imaging device 20 is performed, converted into a digital signal by the A / D converter 98, and stored as radiation image information in the image memory 108 by the control unit 112. . Next, in the processing unit 102, the magnification adjustment unit 110 calculates the magnification based on the imaging position information stored in the imaging position information memory 106, and adjusts the magnification of the radiation image information stored in the image memory 108. To do.

  In this case, when the magnification of the radiation image information captured by the first imaging device 18 is “1” and the distance between the radiation source 26 of the first imaging device 18 and the electronic cassette 60 is L0, the second imaging device 20 The magnification of the captured radiographic image information is (L0 + L1) / L0. Therefore, the magnification adjustment unit 110 transmits the adjusted radiographic image information to the console 16 after multiplying the radiographic image information stored in the image memory 108 by L0 / (L0 + L1). In the console 16, the radiation image information is subjected to image processing by the image processing unit 50 and stored in the image memory 52.

  Here, when the image memory 52 stores the radiographic image information of the close-contact imaging imaged by the first imaging device 18 and the radiographic image information imaged by the second imaging device 20, the second imaging device 20. The radiographic image information of the image photographed by the electronic cassette 60 is adjusted by the magnification adjustment unit 110 of the electronic cassette 60 so as to be the same magnification as the radiographic image photographed by the first photographing device 18. Accordingly, even when radiographic images of the same subject 56 are captured at different magnifications by different imaging devices, they can be displayed on the display unit 54 at the same magnification as the close-contact imaging captured by the first imaging device 18.

  In addition, when performing chest imaging of the subject 56 with the third imaging device 22, the imaging is performed in the same manner as with the second imaging device 20, the magnification is adjusted, and the close-up image captured by the first imaging device 18 is displayed on the display unit 54. It can be displayed at the same magnification as shooting.

  Next, a radiographic imaging system 10A of the second exemplary embodiment of the present invention will be described.

  As shown in FIG. 5, the console 16 </ b> A constituting the radiographic image capturing system 10 </ b> A performs image processing including magnification adjustment for the radiographic image information acquired from the first image capturing device 18, the second image capturing device 20, and the third image capturing device 22. An image processing unit 50A to perform, and an imaging position information memory 55 that stores imaging position information used to calculate the magnification for adjusting the magnification of the radiation image information. Further, as shown in FIG. 6, the processing unit 102A of the electronic cassette 60A is provided with a photographing position information memory 106 and an image memory 108, and a magnification adjusting unit 110 for the processing unit 102 of the electronic cassette 60 shown in FIG. It has a configuration that does not have.

  Next, a case where the second imaging device 20 is controlled using the console 16A and the electronic cassette 60A to perform chest imaging of the subject 56 will be described. Note that the description of the same operations as those of the console 16 and the electronic cassette 60 is omitted.

  The electronic cassette 60A transmits the imaging position information of the second imaging device 20 stored in the imaging position information memory 106 and the radiographic image information with unmagnified magnification stored in the image memory 108 to the console 16A.

  The control unit 42 of the console 16A temporarily stores the radiation image information in the image memory 52A and stores the imaging position information in the imaging position information memory 55. The image processing unit 50A calculates the magnification (L0 / L0 + L1) based on the imaging position information stored in the imaging position information memory 55, adjusts the magnification of the radiation image information stored in the image memory 52, and sets the image Store in the memory 52. The radiographic image stored in the image memory 52 is a radiographic image subjected to image processing at the same magnification as the radiographic image captured by the first imaging device 18, and the radiographic image captured by the first imaging device 18 as necessary. The image and the radiographic image captured by the second imaging device 20 are displayed on the display unit 54.

  Note that the shooting position information stored in the shooting position information memory 64 of the shooting tables 32 and 38 is transmitted directly from the shooting tables 32 and 38 to the console 16A and stored in the shooting position information memory 55 without using the electronic cassette 60. The magnification may be adjusted by the image processing unit 50A based on the stored shooting position information.

  Alternatively, the imaging position information for the imaging tables 32 and 38 may be stored in the imaging position information memory 55 in advance, and the magnification of the radiation image information may be adjusted using the stored imaging position information. That is, when the electronic cassette 60A is loaded into the slot 34 of the imaging table 32, the identification code of the imaging table 32 is transmitted from the imaging position information memory 64 of the imaging table 32 or the imaging position information memory 106 of the electronic cassette 60A. The magnification may be calculated by specifying the photographing position information stored in the photographing position information memory 55 based on the identification code, and the magnification may be adjusted by the image processing unit 50A.

  Further, without acquiring the shooting position information from the shooting position information memory 64 of the shooting tables 32 and 38, the engineer specifies the shooting table from the console 16, or specifies the shooting table by the shooting instruction information transmitted from the RIS 14. The shooting position information can also be specified. In such a case, the second imaging device 20 and the third imaging device 22 may not include the loading detection unit 62, the imaging position information memory 64, and the transmission / reception unit 66.

  Furthermore, in the radiographic imaging systems 10 and 10A, the second imaging device 20 and the third imaging device 22 are provided with the loading detection unit 62 for detecting the loading state of the electronic cassette 60. A loading detection unit may be provided in the unit 102 to detect the loading state of the electronic cassette 60.

  Furthermore, in the second imaging device 20, an electronic cassette 60 is placed between the imaging table 32 and the subject 56, and a radiographic image obtained by performing close-contact imaging with the subject 56 and the electronic cassette 60 in close contact with each other, A radiographic image captured by loading the electronic cassette 60 in the slot 34 of the second imaging device 20 can also be displayed at the same magnification. In close contact shooting in such a case, the operation setting unit 44 is operated to acquire the shooting position information stored in advance in the shooting position information memory, and the same magnification display process is performed. Similarly to the case of the second imaging device 20, a radiographic image in the case of close-contact imaging with the third imaging device 22, and a radiographic image in the case of imaging with the electronic cassette 60 loaded in the slot 40 of the third imaging device 22 Can be displayed at the same magnification.

  In addition, although the description has been given of the same magnification display as the radiographic image of the close contact imaging captured by the first imaging device 18, the radiographic images captured by the second imaging device 20 and the third imaging device 22 are displayed at the same magnification. You can also.

  Furthermore, for example, when the slot 34 of the second imaging device 20 has a structure in which the loading position of the electronic cassette 60 can be changed, the imaging magnification will be different. In this case as well, radiographic images taken at different loading positions can be obtained. They can also be displayed at the same magnification.
