Description

  The present invention relates to an X-ray imaging system that captures an X-ray image transmitted through a subject, and more particularly, to an imaging method for photographing the same subject in multiple times.

  In recent years, imaging using an X-ray imaging apparatus has been used in various fields, and in particular in the medical field, has become one of the important means for diagnosis. Further, with the progress of digitization, an image sensor that collects image data obtained by an X-ray imaging apparatus as digital data has been put into practical use.

  When X-ray imaging is performed using this imaging sensor, an area larger than the imaging sensor, such as the whole body or the entire length of the lower limbs, may be captured. In this case, a photographing method has been established in which photographing is performed in a plurality of times and a single piece of large image data is obtained by synthesizing the collected image data. This photographing method is generally called long photographing, stitch photographing, divided photographing, or the like.

  There are Patent Document 1 and Patent Document 2 as documents describing the above-described photographing method.

  This long imaging repeats imaging while the X-ray imaging apparatus and the X-ray generation apparatus cooperate in accordance with the operation of the radiologist. When the radiographer determines the number of images to be taken according to the imaging region and imaging range, and selects an imaging protocol from the X-ray imaging device, the X-ray generation device notifies the X-ray generation device, and the X-ray generation device takes an image according to what number of imaging is performed. The sensor position, tube swing angle, and position are determined and preparation for shooting is performed.

  Such long shooting is generally divided into a shooting room where the subject is placed and an operation room where the radiologist performs operations for shooting, and the radiologist travels through each room and proceeds with shooting. To do. At that time, the radiographer determines the number of images to be taken in the operation room in advance according to an instruction from a medical record or the like and selects an imaging protocol, and then moves to the imaging room to position the subject.

It may be necessary to change the number of shots according to the situation during shooting preparation or during shooting. However, in the conventional X-ray imaging system, changes must be made from the console of the X-ray imaging apparatus.
In the X-ray imaging system, there are separate consoles for the X-ray imaging apparatus and the X-ray generation apparatus in the operation room. For this reason, if it is necessary to change the number of radiographs during operation on the console of the X-ray generator, the radiologist must move to the console of the X-ray apparatus and change it. Cannot be changed more easily than the console.

  Therefore, a control device that controls the X-ray imaging apparatus according to an aspect of the present invention is a control device that controls the X-ray imaging apparatus so as to execute divided imaging in which the subject is imaged separately for each predetermined number of partial areas. A setting means for setting the number of division imaging, an output means for outputting the number of imaging to the X-ray generation device, a reception means for receiving a request to change the number of imaging from the X-ray generation device, Determining means for determining whether or not to change the number of shots in response to the reception request.

  With this configuration, the radiologist can change the number of shots at the time of long shooting and perform the shooting end operation in both the shooting room and the operation room. In addition, the operation can be performed on any console of the X-ray imaging apparatus and the X-ray generation apparatus. Accordingly, since the radiologist can easily perform the change or end operation, the movement of the room or the movement between the consoles can be reduced, and the efficiency of the imaging flow can be improved.

[Example 1]
An embodiment in which the present invention is applied to an X-ray imaging system will be described with reference to FIGS. The X-ray imaging system 100 shown in FIG. 1 is divided into an imaging room 1010 in which a subject is placed for imaging and an operating room 1020 in which a radiographer performs an operation for imaging. Further, the apparatus includes an X-ray imaging apparatus 1100 including an imaging sensor 1000, an X-ray sensor unit 1001, and an X-ray generation apparatus 1200 including an X-ray tube 1002 that emits X-rays. The X-ray imaging system 100 is capable of long imaging, and the X-ray imaging apparatus and the X-ray generator are efficiently linked to make it easy for the operator to change the number of long imaging images and to end the imaging. The whole is controlled. Here, the long shooting is a shooting method in which a subject is shot separately for each predetermined number of partial areas. Note that the shooting method to be applied is not limited to this. For example, the present invention can be applied to so-called divided imaging in which one image sensor sequentially irradiates a partial region with X-rays and obtains an image of both hands with one image sensor. In the present embodiment, the term “divided shooting” includes long shooting and so-called divided shooting.

  An X-ray imaging apparatus 1100 includes an imaging sensor 1000, an X-ray imaging apparatus control unit 1101 that controls X-ray imaging, an X-ray imaging apparatus display unit 1103 that displays examination information and a captured image, and an X-ray imaging apparatus operation input unit 1102. Consists of. An X-ray imaging apparatus operation input unit 1102 for inputting examination information, image processing operation, and inspection progress instruction is a first operation unit that receives an input for controlling the X-ray imaging apparatus 1100. The imaging sensor 1000 is an image sensor that detects X-rays and converts them into electrical signals, and includes a phosphor that converts X-rays into visible light and a semiconductor detector that converts light into electrical signals. It may be a semiconductor detector that directly converts X-rays into electrical signals. The X-ray sensor unit 1001 further includes a drive unit (not shown) that moves the imaging sensor 1000 along the subject in conjunction with the X-ray tube 1002 during long imaging.

  The X-ray generator 1200 includes an X-ray generator controller 1201 that controls the generation of X-rays, and an X-ray generator drive controller 1202 that controls the driving of the X-ray sensor unit 1001 and the X-ray tube 1002. . Furthermore, an X-ray generator simple operation input unit 1203 capable of inputting simple information such as X-ray imaging conditions, and an X-ray generator simple display unit 1204 for performing simple display of set X-ray imaging conditions are included. Arranged in the imaging room 1010. Further, an X-ray generator operation input unit 1205 capable of inputting detailed settings of the X-ray generator 1200, details of imaging conditions, and the like, and an X-ray generator display unit 1206 for displaying various detailed information of the X-ray generator 1200 are imaged. Arranged in the chamber 1010. The X-ray generator operation input unit 1205 functions as a second operation unit. Note that the X-ray generator simple operation input unit 1203 may also function as the second operation unit.

  The X-ray generation device control unit 1201 controls the X-ray generation device to execute divided imaging in which the subject is imaged separately for each predetermined number of partial areas.

  The X-ray generator 1200 has a drive unit (not shown) that translates the X-ray tube along the subject or changes the irradiation direction in conjunction with the image sensor 1000 during long imaging. In addition, at the time of so-called divided shooting, the drive unit changes the irradiation direction and controls the aperture according to the position of the image sensor 1000 corresponding to each shooting of divided shooting.

  In addition, the X-ray generation apparatus 1200 includes an output unit that outputs a request for changing the number of imaging and a request for ending the imaging to the X-ray imaging apparatus 1100. In addition, it has a receiving unit (not shown) that receives the number of division imaging from the X-ray imaging apparatus and receives information indicating whether or not a change according to the output change request has been made. These exchange data with an output unit 2008 and a reception unit 2009 of an X-ray imaging apparatus 1100 described later.

  The control unit of the photographing apparatus will be described with reference to FIG. FIG. 2 is a diagram showing functional blocks of the X-ray imaging apparatus control unit 1101. The communication control unit 2000 controls communication with the X-ray generator 1200. A communication I / F 2007 is a wired and / or wireless communication module, and includes an output unit 2008 that outputs signals and other data to the outside, and a reception unit 2009 that receives signals and other data from an external device. The output unit 2008 outputs, for example, the number of division imaging to the X-ray generator control unit 1201. In addition, when there is an instruction to change the number of radiographs according to the input from the first operation unit 1102, the output unit 2008 outputs the change of the radiographing number to the X-ray generator 1200. The receiving unit 2009 receives a request to change the number of radiographs from the X-ray generator control unit 1201.

  The imaging control unit 2001 controls the progress and imaging of the X-ray imaging inspection, stores the imaging conditions during the inspection in the imaging condition storage unit 2005, stores the inspection progress state in the imaging state storage unit 2006, and captures the captured images. Responsible for processing such as saving in the image storage unit 2004. A protocol selection unit 2012 selects an appropriate imaging protocol for patient information input by a user or input from an external device. The imaging protocol indicates one unit of imaging information in which an imaging region and imaging conditions are set. A protocol is selected in accordance with a user selection through the operation unit or an input from an external device.

  The shooting number setting unit 2013 sets the number of shots when performing divided shooting (so-called long shooting or so-called divided shooting). Normally, the value associated with the imaging protocol is set according to the protocol selection, but can be changed according to an input from the operation unit or an external device.

  The image loss determination unit 2014 determines whether or not the captured image is image loss. As a determination method, it is determined whether or not there is a copy failure depending on whether or not there is an input indicating that the copy has been input through the operation unit by the user. The determination can also be made by applying a known image processing algorithm to the captured image.

  For example, the re-shooting instruction unit 2015 interrupts the currently-captured protocol in response to an input from the user, or generates an instruction to re-shoot the already-taken protocol. In response to an instruction to re-photograph, all images photographed with the protocol are treated as damages, a protocol identical to the protocol is generated, and the protocol selection unit 2012 selects the protocol. Further, the imaging control unit 2001 may register a re-imaging protocol at the back of the protocol queue.

  The photographing holding unit 2016 puts the currently photographing protocol or examination on hold in response to an input from the user, for example. Here, the inspection means a group of at least one photographing performed for one subject. In the hold state, the photographing protocol is interrupted and registered as a hold state in a queue for holding in a storage unit (not shown). Note that the queue here may only store an array of pointers associated with imaging protocols and examinations.

  As for the protocol for divided shooting, even if the divided shooting is interrupted and restarted, it is assumed that an appropriate long image cannot be obtained due to the movement or shift of the subject. The protocol may be in an end state.

  The photographing end unit 2017 terminates photographing or inspection in response to a termination request from the user or an external device. In the case of divided shooting, when some of the plurality of shots remain, and there is a request to end shooting, the shooting end unit 2017 ends the shooting protocol or examination.

  In addition, the change request acceptance determination unit 2002 determines whether to change the number of shots in response to reception of a request for changing the number of shots. Information on the shooting state storage unit 2006 is acquired, and it is determined whether a request for changing the number of shots for long shooting can be accepted. When the communication control unit 2000 receives a request to change the number of shots for long shooting, a process is requested to the change request acceptance determination unit 2002 via the shooting control unit 2001. An end request acceptability determination unit 2003 acquires information in the imaging state storage unit 2006 and determines whether it is possible to accept an end request for long shooting. When the communication control unit 2000 receives a shooting end request for long shooting, a process is requested to the end request acceptance determination unit 2003 via the shooting control unit 2001.

  A display control unit 2010 controls display contents of the X-ray imaging apparatus display unit 1103. Specifically, FIG. 9 displays the operation screen of FIG. 10 and controls the display in accordance with a user or an external input. For example, the display control unit 2010 displays a GUI (composite screen 4000) for aligning a plurality of images obtained by the divided shooting. Also, control is performed to change the screen as shown in FIG. The transition determination unit 2011 determines whether or not the display screen may be changed from one screen to another screen. The determination result is notified to the display control unit 2010 and the imaging control unit 2001.

Processing of the X-ray imaging apparatus 1100 having the above-described configuration will be described below.
A process when the X-ray imaging apparatus 1100 receives a request for changing the number of radiographs from the X-ray generation apparatus 1200 will be described with reference to FIG. FIG. 3 is a flowchart when the X-ray imaging apparatus 1100 of this embodiment receives a request for changing the number of radiographs. The processing flow of the request output source X-ray generator 1200 will be described later with reference to FIG.

  First, in response to an instruction from the X-ray imaging apparatus operation input unit 1102 (first operation unit) or an external apparatus, the protocol selection unit 2012 selects a protocol displayed on the long imaging protocol display unit 3002 (S100). . The shooting control unit 2001 stores shooting conditions in the shooting condition storage unit 2005. The shooting number setting unit 2013 acquires shooting number information from information associated with the selected protocol, and sets the shooting number. Further, the shooting control unit 2001 stores in the shooting state storage unit 2006 that the selected long shooting protocol has been started. Then, the communication control unit 2000 is notified of the start of long shooting. In response to the start of long imaging, the communication control unit 2000 causes the output unit 2008 to output notification of the start of long imaging and the total number of images (3) to the X-ray generator 1200 (S101). Thereafter, the receiving unit 2009 receives a change request (two) of the total number of radiographs output in response to an input via the X-ray generation device operation input unit (second operation unit) of the X-ray generation device 1200 ( S102). The communication control unit 2000 notifies that fact and inquires of the change request acceptability determination unit 2002 via the imaging control unit 2001 whether the change request can be accepted. Then, the change request acceptance determination unit 2002 determines whether or not to change the number of shots according to the reception request (S103). The change request acceptance determination unit 2002 performs a process of determining whether a change request can be accepted.

  Based on the determination result of the change request acceptance determination unit 2002, it is checked whether a request for changing the number of shots can be accepted (S104). If the change can be made, the imaging control unit 2001 notifies the communication control unit 2000 that the change request has been accepted. Then, the communication control unit 2000 causes the output unit 2008 to output that the X-ray generator 1200 has received a request for changing the number of radiographs (S105). Furthermore, the shooting number setting unit 2013 changes the shooting number in response to the received change request, and changes the shooting number when it is determined that the shooting number is to be changed. The imaging control unit 2001 stores the changed information in the imaging condition storage unit 2005 and instructs the X-ray imaging apparatus display unit 1103 to update the display (S107). If the change request cannot be accepted in S104, the imaging control unit 2001 notifies the communication control unit 2000 that the change request cannot be accepted. Then, the communication control unit 2000 notifies the X-ray generator 1200 that the request for changing the number of radiographs has not been accepted (S106). Here, since the change request from 3 sheets to 2 sheets has been received, the X-ray generation apparatus 1200 is notified that it has been received normally.

  Note that the display change and screen transition of the photographing screen 3000 at that time are as shown in FIG. 11 according to the control of the display control unit 2010. The remaining number display section 3004 of the long photographing protocol of FIG. 11A is updated from the remaining number of three to two as shown in FIG. 11B. The photographing is repeated (S108) until the number of photographed images matches the total number of photographed images (S109). The transition of the shooting screen 3000 is changed from FIG. 11B to FIG. 11C, and the shot image is displayed on the preview image display unit 3001 and the thumbnail image display unit 3003. When the shooting of all the shots is completed, it is checked whether or not the setting is to automatically shift to the composite screen (S110). Here, since the total number of shots has been changed from three to two, when two shots are taken, all shots are completed, and an automatic transition check to the composite screen is performed. If the automatic transition is valid, the composition screen 4000 is displayed (S111). The screen transition at that time is as shown in FIG. 11 (c) to FIG. 11 (d). When adjustment is performed on the composition screen 4000 and the OK button 4009 is pressed, composition processing is performed (S112), and the composite image is stored in the image storage unit 2004 (S113). Thereafter, when the imaging control unit 2001 notifies the communication control unit 2000 of the end of the long imaging, the imaging control unit 2001 notifies the X-ray generation apparatus 1200 of the end of the long imaging (S114).

  Next, the overall flow of the end of shooting at the time of long shooting according to the present embodiment will be described with reference to FIGS. 1, 2, 4, 6, 8, 9, 10, and 12.

  Shooting may end in the middle because the subject has moved or the necessary range is included in the captured image. Also in this case, it cannot be easily finished from the console of the X-ray generator. In addition, when the long imaging is finished halfway from the X-ray imaging apparatus, the end of the imaging is notified to the X-ray generation apparatus, and preparation for the next imaging is advanced in advance, so that the efficiency of the imaging flow is expected.

  In order to start long imaging, the radiologist inputs inspection information using the X-ray imaging apparatus operation input unit 1102 and the X-ray imaging apparatus display unit 1103 in the operation room 1020 and starts the inspection. Then, after selecting the long shooting protocol with the total number of shots being 3, the camera moves to the shooting room 1010 and positions the subject. At this time, it is assumed that it is determined from the height of the subject that the necessary area can be sufficiently captured with two images instead of three. Then, the radiologist uses the X-ray generator simple operation input unit 1203 and the X-ray generator simple display unit 1204 to change the number of radiographs.

  FIG. 4 is a flowchart when the X-ray imaging apparatus 1100 of this embodiment receives an imaging end request. Note that the shooting end request is a request for ending divided shooting with the number of shots that have been completed, and can be regarded as a special case of a request for changing the number of shots.

  Assume that the radiographer determines that the second image may be completed because all necessary areas are included in the captured image while the image capturing of the long image capturing protocol is in progress. Then, the radiologist uses the X-ray generation device operation input unit 1205 and the X-ray generation device display unit 1206 to perform an imaging end operation.

  Details of the X-ray imaging apparatus 1100 at that time will be described below.

  First, when the long photographing protocol is selected (S200), the photographing control unit 2001 stores the photographing condition in the photographing condition storage unit 2005, and further stores the start of the long photographing protocol in the photographing state storage unit 2006. Then, the communication control unit 2000 is notified of the start of long shooting. In response to the start of long imaging, the communication control unit 2000 notifies the X-ray generator 1200 of the start of long imaging and the total number of images (3) (S201). The shooting is repeated until the number of shot images matches the total number of shots (S202). After the second image has been captured, the communication control unit 2000 receives a long image capturing end request and an image capturing end number (2 images) from the X-ray generator 1200 in a state where the total number of images has not been reached (S203). Then, through the imaging control unit 2001, the end request acceptance determination unit 2003 is inquired whether the end request can be accepted. Then, the end request acceptability determination unit 2003 performs a process for determining whether the end request can be accepted (S204).

  Based on the determination result of the end request acceptance determination unit 2003, it is checked whether or not a photographing end request can be accepted (S205). If the photographing control unit 2001 can be terminated, the imaging control unit 2001 notifies the communication control unit 2000 that the termination request has been accepted. Then, the communication control unit 2000 notifies the X-ray generation apparatus 1200 that the imaging end request has been received via the communication I / F 2007 (S206). If the termination request cannot be accepted in S205, the imaging control unit 2001 notifies the communication control unit 2000 that the termination request cannot be accepted. Then, the communication control unit 2000 notifies the X-ray generator 1200 that the imaging end request has not been received (S207). Here, since the end request is received with the end number of two sheets, the X-ray generator 1200 is notified that it has been normally received. Whether or not the end request can be accepted is regarded as the end of all shooting, and it is checked whether or not it is set to automatically transition to the composite screen (S208). When the automatic transition is valid, the display control unit 2010 displays the display content of the display unit 1103 on the GUI (shooting screen 3000) position for shooting in response to the reception unit 2009 receiving the end request before the shooting is finished. Change to the GUI (combination screen 4000) for matching.

  The composite screen 4000 is displayed (S209). Note that the screen display change and screen transition when the number of shots is 2 and a shooting end request is made are as shown in FIG. 12 according to the control of the display control unit 2010. Long shooting is started on the shooting screen 3000 of FIG. 12A, and a shooting end request is accepted in the state of the shooting screen 3000 of FIG. Then, if the automatic transition to the composite screen is valid, the screen transitions to the composite screen 4000 in FIG. 12C, and the composite processing operation becomes possible. When adjustment is performed on the composition screen 4000 and the OK button 4009 is pressed, composition processing is performed (S210), and the composite image is stored in the image storage unit 2004 (S211). Thereafter, when the imaging control unit 2001 notifies the communication control unit 2000 of the end of the long imaging, the imaging control unit 2001 notifies the X-ray generation apparatus 1200 of the end of the long imaging (S212).

  FIG. 5 is a flowchart for determining whether or not to accept a request for changing the number of shots according to this embodiment. Details of the change request acceptance / rejection determination unit 2002 will be described with reference to FIG.

  When the change request acceptance determination unit 2002 receives a request for changing the number of long shots (two) (S300), the acquisition request is acquired from the shooting state storage unit 2006 (S301). It is assumed that the acquired shooting state includes protocol information during shooting and progress information including the number of shot images. It is checked whether or not the long shooting is being performed from the acquired shooting state (S302). If it is not during long shooting, it is determined that the change request cannot be accepted (S306). Here, since a long shooting protocol is selected and shooting is in progress, it is determined that long shooting is in progress. Next, it is checked whether or not the number of shot images included in the acquired shooting state is zero (S303). If the number is zero, that is, if no image is taken, it is determined that the change request can be accepted (S305). Here, since no image is taken, it is determined that the change request can be accepted. If even one image has already been shot, it is checked whether the requested total number of shots is larger than the number of shot images (S304). If the requested total number of shots is large, it is determined that a change request can be accepted (S305). However, when the requested total number of shots is equal to or less than the number of shot images, it is determined that the change request cannot be accepted (S306).

  FIG. 6 is a flowchart for determining whether or not the photographing end request can be accepted according to the present exemplary embodiment, and relates to the end request accepting and not determining unit 2003 in FIG.

  Details of the end request acceptance determination unit 2003 will be described. Upon receipt of the shooting end request and the number of shots to end (2) (S400), the end request acceptance determination unit 2003 acquires the shooting state from the shooting state storage unit 2006 (S401). It is assumed that the acquired shooting state includes protocol information during shooting and progress information including the number of shot images. It is checked whether or not the long shooting is being performed from the acquired shooting state (S402). If it is not during long shooting, it is determined that the end request cannot be accepted (S405). Here, since a long shooting protocol is selected and shooting is in progress, it is determined that long shooting is in progress. Next, it is checked whether or not the number of shot images included in the acquired shooting state matches the requested shooting end number (S403). If they match, the end request can be accepted (S404). If they do not match, it is determined that the end request cannot be accepted (S405). Here, since the number of captured images is equal to two and the requested number of captured images is equal to two, it is determined that the end request can be accepted.

  FIG. 7 is a flowchart at the time of requesting a change in the number of shots of the X-ray generator 1200 of this embodiment.

  First, the receiving unit (not shown) of the X-ray generator 1200 receives the start of long imaging and the total number of images (3) from the communication I / F 2007 (S1100). Based on the number of received images, preparation for imaging is performed to set the angle, position, etc. of the X-ray tube 1002 (S1101). When the radiologist determines that the necessary area can be imaged with 2 instead of 3 based on the height of the subject, the number of images to be captured is changed using the X-ray generator simple operation input unit 1203 and the X-ray generator simple display unit 1204 I do. Then, an output unit (not shown) of the X-ray generation apparatus control unit 1201 outputs a request for changing the number of radiographs to the communication I / F 2007 of the X-ray imaging apparatus 1100 (2 sheets). ). Further, the receiving unit (not shown) receives the result indicating whether or not the change request is received from the communication I / F 2007 of the X-ray imaging apparatus 1100 as information indicating whether or not the change according to the change request has been performed (S1103). It is checked whether the request has been accepted (S1104). If the request is accepted, the number is updated to the requested total number of shots, and the X-ray tube, angle position, sensor unit, etc. are adjusted (S1105). Thereafter, the shooting is repeated until the total number of shots is reached (S1106). When all shots are completed, a long shooting end notification is received from the communication control unit 2000 (S1107), and necessary long shooting end processing is performed (S1108). The next photographing request can be accepted.

  In this embodiment, the change operation is performed using the X-ray generator simple operation input unit 1203 and the X-ray generator simple display unit 1204. However, the X-ray generator operation input unit 1205 and the X-ray generator display are used. A similar change operation can be performed in the unit 1206.

  Furthermore, in the present embodiment, the overall flow when changing the number of shots in the unshooted state in long shooting has been shown, but it is possible to change the number of shots in the same manner even after the start of shooting.

  FIG. 8 is a flowchart at the time of an imaging end request of the X-ray generator 1200 of the present embodiment.

  First, when the X-ray generator 1200 receives the start of long imaging and the total number of images (3) from the communication control unit 2000 (S1200), the angle and position of the X-ray tube 1002 are based on the received number of images. The X-ray sensor unit 1001 and the like are prepared for imaging (S1201). Thereafter, in the middle of repeating the imaging until the total number of images is reached (S1202), the X-ray generator operation input unit is determined when it is determined that the second imaging can be completed because all the necessary areas are included by the radiologist. An imaging end operation is performed using 1205 and the X-ray generator display unit 1206. Then, the X-ray generator control unit 1201 makes an imaging end request to the communication control unit 2000 with the imaging end number set to two (S1203). The result of whether or not the end request is accepted is received (S1204), and it is checked whether or not the request is accepted (S1205). If the request is not accepted, shooting is repeated until the total number of shots is reached (S1206). When the request is accepted, all shooting is completed, and a long shooting end notification is received from the communication control unit 2000 (S1207). Then, necessary long photographing end processing is performed (S1208), and the next photographing request can be accepted.

  In this embodiment, the end operation is performed using the X-ray generator operation input unit 1205 and the X-ray generator display unit 1206. However, the X-ray generator simple operation input unit 1203 and the X-ray generator simple display are performed. A similar end operation can be performed in the unit 1204.

  The patient information display unit 3007 is provided with an edit button 3008 to change patient information.

  When performing long shooting, the shooting protocol list display unit 3014 displays a shooting protocol protocol in the shooting protocol display 3002. The long photographing protocol display unit 3002 includes a thumbnail image display unit 3003 that displays thumbnails of captured images, a remaining number display unit 3004 that displays the remaining number of long images, a composite image display unit 3005 that displays a composite image, and a composite image. It consists of a composition button 3006 for transitioning to a screen for generating an image.

  In response to pressing of the re-shooting button 3009, the re-shooting instruction unit 2015 generates a re-shooting protocol and starts re-shooting. In response to pressing of the copy button 3010, the copy determination unit 2014 determines that the image is a copy. In response to pressing of the examination hold button 3012, the imaging suspension unit 2016 puts the examination on hold. When the inspection end button 3013 is pressed, the inspection is terminated.

  FIG. 10 shows an example of the composite screen, which is displayed on the X-ray imaging apparatus display unit 1103. The composite screen 4000 includes a composite image preview display unit 4001 that displays a composite image and a composite image thumbnail display unit 4005 that displays thumbnails of the composite image.

  According to the present embodiment, the radiologist can change the number of shots at the time of long shooting and perform the shooting end operation in both the shooting room and the operation room. In addition, the operation can be performed on any console of the X-ray imaging apparatus and the X-ray generation apparatus. Accordingly, since the radiologist can easily perform the change or end operation, the movement of the room or the movement between the consoles can be reduced, and the efficiency of the imaging flow can be improved.

[Example 2]
Next, an embodiment corresponding to re-shooting due to reasons such as the subject moving during long shooting will be described below. Since the system configuration is the same as that of the first embodiment, the description thereof is omitted. The X-ray imaging system according to the present embodiment can execute the following processing in addition to the processing of the first embodiment.

  If the radiographer determines that re-imaging is necessary due to reasons such as long-shot imaging that cannot be correctly combined due to detection of body movement of the subject, or a lack of imaging area, the X-ray generator simple operation input unit 1203 , And the X-ray generator simple display unit 1204 are used to perform a re-imaging operation.

  The re-imaging instruction unit 2015 responds to the number of images after the change when there is an instruction for re-imaging after the receiving unit 2009 receives a request to change the number of images from the control unit 1201 of the X-ray generator 1200. Generate setting information for divided shooting.

If the re-shooting instruction is received after the receiving unit receives the request to end the shooting, the setting information of the divided shooting corresponding to the number of shots of the already started divided shooting is acquired. Details of the X-ray imaging apparatus 1100 will be described below.

  FIG. 13 is a flowchart of the present embodiment and relates to the imaging control unit 2001 of FIG. When the radiographer determines that re-imaging for long imaging is necessary, the radiographer presses a re-imaging button 3009 on the imaging screen 3000. Then, the reshooting instruction unit 2015 detects a reshooting request for long shooting (S700), and generates a shooting condition for long shooting requested from the shooting condition storage unit 2005. The information on the imaging conditions includes information on whether or not a request for changing the number of shots has been received from the X-ray generator 1200 and whether or not a request for termination of imaging has been received. The imaging control unit 2001 checks whether or not the long imaging requested for reimaging has received an imaging end request from the X-ray generator 1200 (S701). If an imaging end request has not been received in S701, the imaging control unit 2001 checks whether an imaging number change request has been received from the X-ray generator 1200 (S702). If it is determined in S702 that the shooting change request has been accepted, the reshooting instruction unit 2015 generates a long shooting protocol with the changed number of shots (S703). If it is determined in S701 that a shooting end request has been received, and if it is determined in S702 that a shooting number change request has not been received, the reshooting instruction unit 2015 generates a long shooting protocol with the original number of shots. (S704). Note that the re-shooting instruction unit 2015 may acquire an appropriate shooting protocol stored in the shooting condition storage unit 2005 without generating a new shooting protocol.

  FIG. 14 is an example of screen transition at the time of re-imaging after accepting a request for changing the number of radiographs in this embodiment, and is displayed on the X-ray imaging apparatus display unit 1103.

  For example, when a long shooting protocol for which a shooting change request has been made to change the shooting number to 2 for all 3 shots is taken again, the shooting protocol list display unit 3014 changes the screen as shown in FIG. Since the total number of shots is 3 at the start of shooting, the remaining number display unit 3004 displays the remaining number of 3 as shown in FIG. In this state, if the X-ray generator 1200 accepts that the number of shots is changed to 2 in response to a request to change the number of shots, the remaining number display unit 3004 is displayed as 2 remaining as shown in FIG. When the radiographer presses the re-photograph button 3009 in the state of FIG. 14C after the repeated shooting and the composite image is generated, the captured image is treated as a loss of image as shown in FIG. Thus, a long shooting protocol with a total number of shots of 2 is generated.

  FIG. 15 is an example of screen transition at the time of re-imaging after acceptance of the end update request in this embodiment, and is displayed on the X-ray imaging apparatus display unit 1103.

  Also, for example, when a long shooting protocol for which a shooting end request is issued with two shots for all three shots is shot again, the shooting protocol list display unit 3014 changes the screen as shown in FIG. Since the total number of shots is 3 at the start of shooting, the remaining number display unit 3004 displays the remaining number of 3 as shown in FIG. In the state of FIG. 15B in which imaging is started and the number of images to be taken is 2, when an imaging end request is received from the X-ray generator 1200, the process proceeds to FIG. In this state, when the radiographer presses the re-imaging button 3009, the captured image is treated as a loss of image as shown in FIG. 15 (d), and a long imaging protocol with a total of 3 images is newly generated. The

  According to this embodiment, when the radiographer re-photographs, if the number of radiographs is changed by the X-ray generator 1200, the long radiography protocol is generated with the post-change radiographing number, so the radiographing is changed again. Save time and effort. Further, when the radiographing is completed by the X-ray generator 1200, the long imaging protocol is generated with the original number of radiographs, so that it is easy to perform the imaging again by detecting the body movement of the subject.

[Example 3]
Next, an embodiment in which the composite screen transition after receiving the imaging end request is controlled according to the state of the X-ray imaging apparatus 1100 will be described below. Since the system configuration is the same as that of the first embodiment, the description thereof is omitted. The X-ray imaging system according to the present embodiment can execute the following processing in addition to the processing of the first embodiment and / or the second embodiment.

  As shown in the first embodiment, when the radiologist performs an imaging end operation, an X-ray generation apparatus 1200 issues an imaging end request asynchronously. Then, it is determined that the photographing end request can be accepted, and a transition is made to the composition screen 4000. At this time, a message screen is displayed on the photographing screen 3000, and the transition to the composition screen 4000 may have to be controlled. A warning regarding the X-ray imaging apparatus 1100 or the X-ray generation apparatus 1200 of the X-ray imaging system 100 is displayed on the display unit 1103 by the display control unit 2010.

  The transition determination unit 2011 determines the type of warning display when the reception unit 2009 receives a request to change the number of shots during warning display.

  In response to this determination, the display control unit 2010 waits for a user input for a warning to display a GUI for alignment (composite screen 4000) or immediately after receiving a request, a GUI for alignment. Controls whether to display (synthesize screen 4000).

  Details of the X-ray imaging apparatus 1100 at that time will be described below. FIG. 16 is a flowchart of this embodiment and relates to the imaging control unit 2001 of FIG.

  For example, it is assumed that an imaging end request is issued from the X-ray generator 1200 after two images are captured for a long image with three images. Then, the imaging control unit 2001 inquires whether an end request can be accepted. If the end request can be accepted as a result (S800), it checks whether the end number is greater than 1 (S801). When the number of photographed images is one or less, since the composition process is unnecessary, the transition determination unit 2011 determines that the composition screen transition is unnecessary (S808). If there are two or more shot images, the shooting control unit 2001 checks whether or not automatic transition to the composite screen is set to be valid (S802). If it is invalid, it is not necessary to automatically transition to the composite screen, so it is determined that the composite screen transition is not required (S808). If it is valid, the imaging control unit 2001 checks whether a message dialog is being displayed on the X-ray imaging apparatus display unit 1103 (S803). If the message dialog is not displayed, it is determined that there is no problem in transitioning to the composite screen, and therefore it is determined to transition to the composite screen (S807). When the message dialog is displayed, it is checked whether the displayed message is a synchronous message displayed in synchronization with the operation of the radiologist or an asynchronously displayed message regardless of the operation (S804). . When displayed in synchronization with the operation, the operation by the confirmation of the radiologist may affect the next processing. For example, in the case of a message for ignoring the warning and continuing the image processing, the image processing is executed if the radiologist is OK, and if the message is cancelled, nothing is returned, which may affect the image after transition of the composite screen. . For this reason, if it is determined in S804 that the message is a synchronization message, a user confirmation wait state is entered (S805). Then, after confirming the message by the radiologist, the message dialog is closed and the processing based on the selection is appropriately performed (S806), and then it is determined that the transition to the composite screen is made (S807). If it is determined in step S804 that the message is an asynchronous message, the asynchronous message does not affect the next operation at any time, for example, the transfer has failed. S807).

  FIG. 17 is an example of a screen transition when an imaging end request is received during the display of the synchronization message in this embodiment, and is displayed on the X-ray imaging apparatus display unit 1103.

  For example, as shown in FIG. 17A, when an imaging end request is received in a state where the synchronization message dialog 3100 is displayed, the screen does not immediately shift to the synthesis screen 4000 and waits for confirmation by the radiologist. When the radiologist presses the OK button or the cancel button, the synchronization message dialog 3100 is closed, and after the processing according to the selection is completed, the screen transitions to the composition screen 4000 in FIG. When the composite screen 4000 is closed, the screen transitions to the shooting screen 3000 in FIG. At this time, the synchronization message dialog 3100 is in a closed state.

FIG. 18 shows an example of screen transition when an imaging end request is received during asynchronous message display in this embodiment, and is displayed on the X-ray imaging apparatus display unit 1103.
In contrast to the above-described case, for example, when an imaging end request is received in a state where the asynchronous message dialog 3200 is displayed as shown in FIG. 18A, the asynchronous message dialog 3200 is displayed while the asynchronous message dialog 3200 is displayed. ) To the composition screen 4000 of FIG. When the composite screen 4000 is closed, the screen transitions to the shooting screen 3000 in FIG. 18C, and the content of the message can be confirmed while the asynchronous message dialog 3200 is displayed.

  In this example, when the synchronous message dialog 3100 is displayed, the uniform user confirmation wait state is shown. However, when the classification is further performed and the composite image generation is not affected, the asynchronous message dialog 3200 is displayed. The same processing may be performed.

  According to the present embodiment, the transition to the composite screen 4000 is smoothly performed when a photographing end request is received in a state where a message is displayed on the photographing screen 3000.

[Example 4]
An embodiment in which the photographing end request is integrated into the photographing change request will be described below.

  FIG. 19 is a configuration diagram of the X-ray imaging system function according to the fourth embodiment, which is a part of the X-ray imaging apparatus control unit 1101. 2 that are the same as those in FIG. In this embodiment, the operation of the radiologist when it is determined that the number of shots needs to be changed and the end of shooting is necessary is the same as that in the first embodiment, and the X-ray imaging apparatus control unit 1101 and the X-ray generation apparatus control unit 1201 Some exchanges are different. In the first embodiment, the total photographing number change request and the photographing end request at the time of long photographing are regarded as different requests, but in this embodiment, the photographing end request is made with a request common to the photographing number change request.

  For example, it is assumed that the radiographer determines that the second image can be completed because all necessary regions are included in the captured image while the image capturing of the long imaging protocol is in progress. Then, the radiologist performs an imaging end operation using the X-ray generator operation input unit 1205 and the X-ray generator display unit 1206.

  FIG. 20 is a flowchart of the X-ray imaging apparatus 1100 of the present embodiment.

  First, when the protocol displayed on the long photographing protocol display unit 3002 is selected (S500), the photographing control unit 2001 stores the photographing condition in the photographing condition storage unit 2005, and further the long state in the photographing state storage unit 2006. Memorize the start of the shooting protocol. Then, the communication control unit 2000 is notified of the start of long shooting. In response to the start of long imaging, the communication control unit 2000 notifies the X-ray generator 1200 of the start of long imaging and the total number of images (3) (S501). The shooting is repeated until the number of shot images and the total number of shots match. After the second image is completed, the communication control unit 2000 accepts a change request and a change number (two) from the X-ray generator control unit 1201 in a state where the total number of images has not been reached (S502). After that, it is inquired to the request acceptance determination unit 2100 via the imaging control unit 2001 whether the change request can be accepted. Then, the request acceptance determination unit 2100 determines whether the request can be accepted (S503).

  Based on the determination result of the request acceptance determination unit 2100, it is checked whether the request can be accepted (S504). When the request can be accepted, the imaging control unit 2001 notifies the communication control unit 2000 that the request has been accepted. Then, the communication control unit 2000 notifies the X-ray generator 1200 that the request has been accepted (S505). If the request cannot be accepted in step S504, the imaging control unit 2001 notifies the communication control unit 2000 that the request cannot be accepted. Then, the communication control unit 2000 notifies the X-ray generator 1200 that the request has not been accepted (S506). Here, since it is determined that the termination request can be accepted, the X-ray generator 1200 is notified that the termination request has been received normally. Next, the shooting control unit 2001 determines whether the received request is a request for changing the number of shots or a request to end shooting (S507). If it is determined in S507 that the number of shots to be changed is requested, the imaging control unit 2001 stores the changed information in the imaging condition storage unit 2005 and instructs the X-ray imaging apparatus display unit 1103 to update the display (S508). If it is determined in S507 that the request is to end shooting, or shooting is repeated until the total number of shots has been reached (S509), if it is determined that shooting has ended (S510), it is checked whether or not the setting is automatically changed to the composite screen. (S511). If the automatic transition is valid, the composition screen 4000 is displayed (S512). When adjustment is performed on the composition screen 4000 and the OK button 4009 is pressed, composition processing is performed (S513), and the composite image is stored in the image storage unit 2004 (S514). Thereafter, when the imaging control unit 2001 notifies the communication control unit 2000 of the end of long imaging, the imaging control unit 2001 notifies the X-ray generation device 1200 of the end of long imaging (S515).

  Details of the request acceptance determination unit 2100 will be described here. FIG. 21 is a flowchart for determining whether a request can be accepted according to the present embodiment, and relates to the request acceptance determination unit 2100 in FIG. Upon receiving the change request and the number of changes (two) (S600), the request acceptance determination unit 2100 acquires the shooting state from the shooting state storage unit 2006 (S601). It is assumed that the acquired shooting state includes protocol information during shooting and progress information including the number of shot images. It is checked whether or not the long shooting is being performed from the acquired shooting state (S602). If it is not during long shooting, it is determined that the change request cannot be accepted (S608). Here, since a long shooting protocol is selected and shooting is in progress, it is determined that long shooting is in progress. Next, it is checked whether or not the number of shot images included in the acquired shooting state is 0 (S603). If the number is 0, that is, if no image is taken, it is determined that a change request for the number of shots can be accepted (S605). Here, since the number of captured images is two, the process proceeds to the next step. Next, it is checked whether the requested total number of shots is larger than the number of shot images (S604). If the requested total number of shots is large, it is determined that a change request can be accepted (S606). Here, since the number of captured images is two and the total number of captured images is two, which is not larger than the number of captured images, the process proceeds to the next step. Next, it is checked whether or not the number of captured images matches the requested number of captured images (S605). If they match, the end request can be accepted (S607), and if they do not match, it is determined that the end request cannot be accepted (S608). Here, since the number of captured images is equal to two and the requested number of captured images is equal to two, it is determined that the end request can be accepted.

  According to the present embodiment, similar to the first embodiment, since the radiologist can easily perform the change and end operations, the movement of the room and the movement between the consoles can be reduced, and the efficiency of the imaging flow can be improved.

[Other Examples]
In long shooting, if a loss of image occurs during shooting, an appropriate long image may not be obtained due to the movement of the subject even if shooting is performed again from the middle. Therefore, if a shooting loss occurs, even if a request for changing the number of shots is received, the number of shots is not changed in response to the request, and the shooting end unit 2017 ends the shooting protocol as it is. For example, when the image loss determination unit 2014 determines that an image that has been captured before the end of divided imaging is a failure, and then receives a request to change the number of images from the X-ray generator, the output unit 2008 A request for changing the number of shots corresponding to the request is not output. In the case of so-called divided shooting, since there is little influence on the entire divided shooting due to the movement of the subject, the shooting control unit 2001 should continue shooting even if the shooting determination unit 2014 determines that the shooting has failed. Good.

  Similarly, even when a request for changing the number of imaging is received from the X-ray generator 1200 when the imaging protocol for long imaging is put on hold by the imaging holding unit 2016, the change request acceptance determination unit 2002 responds to the request. It is determined not to accept a change in the number of shots according to the response. When the photographing suspension state is set, the photographing control unit 2001 ends the photographing protocol. In the case of so-called divided shooting, control is continued as it is.

  However, even after entering the hold state, if the number of shots has already been set due to a request for changing the number of shots from the X-ray generator 1200, the imaging control unit 2001 cancels the hold state. Suppose that the protocol is in an end state. As a result, there is no possibility of being put on hold in spite of substantially ending, and the user-friendliness is improved.

  As described above, when the shooting for the number of divided shooting is not completed, it is determined that the image of the divided shooting is defective, or the shooting for the number of shooting of the divided shooting is not completed. Sometimes, when the divided shooting protocol is put on hold, the divided shooting is ended. Thereby, it is possible to reduce the exposure dose of the subject by preventing a long image that is difficult to be properly aligned from being generated before the end of all imaging.

  In the above-described embodiment, “photographing” refers to a period from when the protocol selection unit 2012 selects a protocol in accordance with an input from the operation unit to when the protocol photographing is finished. If the examination is suspended or the examination is completed, it is assumed that the photographing of the protocol is finished.

  Control processing of the X-ray imaging apparatus in the above-described embodiment can also be realized by hardware of the information processing apparatus and program code. In this case, the information processing apparatus has at least one CPU, RAM, ROM, external storage device, storage medium drive, and I / F (interface), which are connected to each other by a bus. In addition, a monitor as a display unit and a keyboard and a mouse as operation units are connected to the apparatus. The ROM stores computer-readable program code for executing the processes shown in the flowcharts of FIGS. 2 to 8, 13, 16, 20, and 21 described above. In addition, the program stores the display image and the display control program for realizing the screen display and transition processing of the screen display shown in FIGS. 9 to 12, 14, 15, 17, and 18. Yes. The processing of the above-described embodiment can be realized by developing this in the RAM and the CPU executing the instruction shown in the program code.

  In this case, the program itself and the recording medium storing the program constitute the invention. Note that the recording medium here includes non-temporary hardware memory including cache memory or volatile memory.

  In addition, the processing executed by each functional block shown in FIG. 1, FIG. 2, FIG. 19, etc. may be divided into a plurality of circuit blocks and may be mounted as a single circuit. Further, the functions of the X-ray imaging apparatus may be executed by being distributed to a plurality of apparatuses. Furthermore, the function of the X-ray imaging system may be realized by a single device. For example, the X-ray imaging apparatus control unit 1101 may be a single control apparatus, and the imaging sensor 1000, the X-ray imaging apparatus operation input unit 1102, and the X-ray imaging apparatus display unit 1103 may be controlled.

  Similarly for the X-ray generator 1200, the X-ray generator controller 1201 may be a single controller. In this case, the control device includes an X-ray source 1002, an X-ray generator drive control unit 1202, an X-ray generator simple display unit 1204, an X-ray generator simple operation input unit 1203, an X-ray generator operation input unit 1205, The line generator display unit 1206 will be controlled.

Give an explanation. In the present invention, the present invention is not limited to this X-ray imaging apparatus, and is applied to, for example, a radiation imaging apparatus that captures a radiographic image of a subject using other radiation (for example, α rays, β rays, γ rays, etc.). It is also possible to do.

  Furthermore, the present invention may be applied to calibration processing of an imaging apparatus such as a fundus camera that receives visible light or narrowband light and performs imaging. In that case, the dose value described above is replaced with the light amount or the light intensity.
