Description

  The present invention relates to a dental digital X-ray imaging apparatus for imaging by intraoral dental X-ray imaging.

  A general digital X-ray imaging method in dentistry is roughly classified into an intraoral method and an oral method depending on whether an imaging device such as a CCD sensor is set in the oral cavity or outside the oral cavity.

  The intraoral method is a method for obtaining clear X-ray images of teeth and periodontal tissue, and the most used is an imaging method called dental imaging.

  Conventionally, in dental imaging, a small X-ray film of about 41 × 31 mm is used so that the teeth are substantially the same as the actual length, and the adjacent teeth are not overlapped.

  A digital X-ray imaging apparatus using a CCD sensor or an imaging plate instead of the X-ray film is widely used. The CCD sensor is an element that transfers electric charges generated by incident X-rays along a semiconductor surface, and is a solid-state imaging element in which a sensor unit and a scanning unit are integrated. A signal from the CCD sensor unit is given to an external personal computer via a cable, imaged by the personal computer, and an X-ray image is displayed on a monitor or the like.

The imaging plate is obtained by applying crystals of a barium fluorohalide compound on a polyester base. When X-rays are incident, electrons are trapped in the holes of halogen ions F ⁺ formed in the crystal, a metastable color center (F center) is formed, and X-ray energy is stored in analog form as image information. The Then, after photographing, when the laser beam of secondary excitation light (reading light) is spot irradiated onto the color center, it is excited to release energy, and the X-ray dose stored in the spot is measured with a light quantity sensor. The signal is converted into a digital quantity to obtain a digital image.

  A digital X-ray imaging apparatus using a CCD sensor for dental imaging is disclosed in Patent Document 1.

  Next, the operation of the present invention will be described with reference to FIGS. 3 to 6 are schematic diagrams showing examples of screens displayed on the display device 56 of the computer device 5. FIG.

  When the computer apparatus 5 enters an operation state for specifying an imaging region, as shown in FIG. 3, a schematic icon 61 indicating the number of each tooth for designating the imaging region is displayed on the display screen 60. To do. Further, the display screen 60 includes an output of the X-ray generator 21, an irradiation time, an operation state display icon 62 indicating the type of the X-ray imaging detector 3 to be used, an icon 63 for distinguishing between adults and children, and an imaging end button. 64, a display area 65 for displaying a photographed X-ray image, an image editing icon 67, and a photographer's name display field 66 are displayed.

  The photographer specifies an imaging region on the display screen 60 using an input device 57 such as a mouse. When the imaging region is specified, the irradiation time is automatically set, and the time is displayed on the operation state icon 62. In order to increase or decrease the irradiation time, the arrow portion is clicked with a mouse or the like. In the example of FIG. 3, 60 kV is selected as the output. In this example, the CCD portion is lit to indicate that a CCD sensor is used as the X-ray imaging detector 3.

  When the photographer selects a part to be photographed using the input device 57 such as a mouse, the tooth icon of the selected part blinks as shown in FIG. In the example of FIG. 4, the upper left 4th and 6th teeth are selected. This blinking state is a temporarily selected state.

  When the part selected by the photographer is definitely determined and the part to be photographed is determined, the blinking icon is further selected using the input device 57 such as a mouse. By this selection, the part to be imaged is specified, and the irradiation time of the part is set. Then, this information is given from the communication control circuit 54 to the apparatus main body control device 20 of the X-ray imaging apparatus main body 2 via the communication cable 4. The apparatus main body control device 20 is provided with information such as an imaging condition based on information such as an imaging region from the computer device 5, and the imaging condition of the apparatus main body control device 20 is set. Then, the computer device 5 gives a standby command for setting the imaging standby state to the X-ray imaging detector 3. When the X-ray imaging detector 3 receives a standby command from the computer device 5, it sets the CCD sensor in a standby state in which imaging can be performed. In the example shown in FIG. 5, the fourth tooth is selected. The selected No. 4 changes from a blinking state to a lighting state. In addition, No. 6 which is not selected is blinking.

  Subsequently, the photographer adjusts the direction of the X-ray irradiation cylinder 21d so as to irradiate X-rays toward the intraoral site.

  On the other hand, an X-ray imaging detector 3 comprising a CCD sensor for detecting an X-ray image is positioned in advance at a position facing the X-ray irradiation cylinder 21d across the intraoral site. Then, by pressing the irradiation button 26, the X-ray image is irradiated to the imaging region, the X-ray image is captured by the X-ray imaging detector 3, the image data is sent to the computer device 5, and the display screen 60 is displayed. It is displayed in area 65. The image data is edited and stored in the memory 52. When the irradiation button 26 is pressed and X-rays are emitted from the X-ray generator 21, a buzzer sounds to notify that X-ray irradiation is in progress and the display device 56 of the computer device 5 is also being irradiated with X-rays. A message is displayed. Accordingly, if the buzzer does not ring even when the irradiation button 26 is pressed, the radiographer has not set the condition of the apparatus main body control device 20 of the X-ray imaging apparatus main body 2 or the X-ray imaging detector 3 is in a standby state. You can see if it is not. In such a case, the photographer presses the irradiation button 26 after redoing the specific operation of the imaging region from the computer device 5.

  When the fourth tooth is photographed, the fourth icon is turned off and the sixth tooth icon is blinking. Then, the blinking sixth tooth icon is further selected using the input device 57 such as a mouse. By this selection, the part to be imaged is specified, and the irradiation time of the part is set. Then, this information is given from the communication control circuit 54 to the apparatus main body control device 20 of the X-ray imaging apparatus main body 2 via the communication cable 4. The apparatus main body control device 20 is provided with information such as an imaging condition based on information such as an imaging region from the computer device 5, and the imaging condition of the apparatus main body control device 20 is set. Then, the computer device 5 gives a standby command for setting the imaging standby state to the X-ray imaging detector 3. When the X-ray imaging detector 3 receives a standby command from the computer device 5, it sets the CCD sensor in a standby state in which imaging can be performed.

  Subsequently, the photographer adjusts the direction of the X-ray irradiation cylinder 21d so as to irradiate X-rays toward the intraoral site.

  On the other hand, an X-ray imaging detector 3 comprising a CCD sensor for detecting an X-ray image is positioned in advance at a position facing the X-ray irradiation cylinder 21d across the intraoral site. Then, by pressing the irradiation button 26, the X-ray image is irradiated to the imaging region, the X-ray image is captured by the X-ray imaging detector 3, and image data of the sixth tooth is sent to the computer device 5 for display. It is displayed in the display area 65 of the screen 60. The image data is edited and stored in the memory 52. In this way, when a plurality of parts are selected, X-ray images of the identified teeth can be obtained sequentially.

  FIG. 6 shows a configuration in which an indicator 68 indicating the time limit for the CCD standby state is displayed on the display screen 60. This standby state restriction state is set to protect the CCD sensor. In this example, it is 180 seconds, but the time varies depending on the type of CCD sensor. When the imaging region is set and the CCD sensor is set in the standby state, the display of the indicator 68 is started. In this example, it is 180 seconds, and within this time, the photographer presses the irradiation button 26 to photograph. When the time limit elapses, irradiation is not started even if the irradiation button 26 is pressed, and setting is performed again.

  Next, the operation of the present invention will be described with reference to the operation flow of FIG. First, when the photographer refers to the display screen 60 of the computer device 5 and selects an imaged region using the input device 57 such as a mouse (step S1), the control unit 50 applies the corresponding display screen based on the selection information. The tooth icon of the imaging part to be blinked is blinked (step S2).

  Subsequently, when the imaging region is specified using the input device 57 such as a mouse, the control unit 50 changes the tooth icon of the corresponding imaging region on the display screen from the blinking state to the lighting state (step S3).

  Thereafter, information such as imaging conditions corresponding to the imaging region specified from the computer apparatus 5 is sent from the communication cable 4 to the apparatus main body control unit 20 of the X-ray imaging apparatus main body 2. Further, the computer apparatus 5 notifies the apparatus main body control unit 20 of the X-ray imaging apparatus main body 2 that the X-ray imaging detector 3 issues a standby command for setting the imaging standby state (step S4). By this notification, the apparatus main body control unit 20 can recognize that the X-ray imaging detector 3 has been set in the imaging standby state.

  Subsequently, the control unit 50 of the computer apparatus 5 gives a standby command for setting the imaging standby state to the X-ray imaging detector 3 (step S5). When receiving the standby command from the personal computer 5, the X-ray imaging detector 3 sets the CCD sensor of the X-ray imaging detector 3 to a standby state in which imaging can be performed.

  The apparatus main body control apparatus 20 on the X-ray imaging apparatus main body 2 side determines whether or not there is a transmission from the computer apparatus 5 (step S11). If there is no transmission from the computer device 5, the process proceeds to step S14 to determine whether or not the irradiation button 26 has been pressed.

  On the other hand, when there is a transmission from the computer apparatus 5, the apparatus main body control apparatus 20 sets the output and imaging time according to the control data based on the received part information (step S12). Then, the apparatus main body control apparatus 20 sets the irradiation OK flag so that X-ray irradiation is possible when the setting of the imaging conditions such as the output and the imaging time is completed (step S13).

  When the irradiation button 26 is pressed, it is determined whether or not the irradiation OK flag is set (step S15). If the irradiation OK flag is not set, the X-ray irradiation is not performed and the process returns to step S11. It waits for transmission of the part information from the computer device 5. As will be described later, since the buzzer sounds during X-ray irradiation, if the buzzer does not ring even when the irradiation button 26 is pressed, the apparatus main body control device 20 of the X-ray imaging apparatus main body 2 must It can be seen whether it is not set or whether the X-ray imaging detector 3 is in a standby state.

  On the other hand, if the irradiation OK flag is set, X-ray irradiation is performed (step S16). Subsequently, the buzzer is sounded and the lamp is turned on so that it can be seen that X-rays are being irradiated (step S17). When X-ray irradiation is performed, information indicating that the computer apparatus 5 is irradiating is given from the communication cable 4, and the display device 56 of the computer apparatus 5 displays that X-ray irradiation is being performed (step S6). ). When X-ray irradiation is completed, the display during X-ray irradiation is turned off. Then, by X-ray irradiation, the X-ray is irradiated on the imaging region, an X-ray image is captured by the X-ray imaging detector 3, and the image data is sent to the computer device 5. On the computer device 5 side, the transmitted image data is acquired (step S7), the image data is edited, a save screen is stored in the memory 52 (step S8), and the operation ends.

  On the X-ray imaging apparatus main body 2 side, when the X-ray irradiation is completed, the imaging operation such as stopping the buzzer and turning off the lamp is stopped (step S18), and the operation is ended.
