  In the communication system as described above, there may be a case where the radiographic department information system (RIS) also transmits a scheduled number of images indicating the number of medical images scheduled to be acquired with the modality to the imaging apparatus. In this case, conventionally, there is no transfer of the planned number of shots between the RIS and the modality, so if there is a loss of copying in the modality or if additional shooting needs to be done, the modality will detect it. There may be a difference between the number of medical images (actual number of shots) sent to the image apparatus and the planned number of shots sent from the RIS. However, in the conventional imaging apparatus, the information on the actual number of shots and the information on the number of planned shots are not integrated and managed, and even if there is a difference between the information on the number of actual shots and the information on the number of planned shots The examiner cannot instantly recognize that fact.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a medical information display device that can automatically acquire information obtained by integrating the actual number of shots and the number of scheduled shots and can refer to it instantaneously. And

  In order to achieve the above object, a medical information display apparatus according to claim 1 of the present invention includes a number-of-photographing-number information acquisition unit that acquires the number of medical images captured by a medical image diagnostic apparatus, and the medical image diagnostic apparatus. A scheduled number-of-photographs information acquisition unit that acquires a planned number of medical images to be captured in the image processing unit, a comparison unit that compares the acquired number of captured images with the scheduled number, and, as a result of the comparison, as a result of the comparison, And a warning section for displaying a warning when there is a difference.

  ADVANTAGE OF THE INVENTION According to this invention, the medical information display apparatus which can acquire automatically the information which integrated the actual imaging | photography number of sheets and the imaging | photography scheduled number of sheets, and can refer to it instantaneously can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an overall configuration of a medical information communication system having a medical information display device according to an embodiment of the present invention. The medical information communication system shown in FIG. 1 includes medical image diagnostic apparatuses (modalities) 1 and 2, a radiation department information system (RIS) 3, an imaging apparatus 4, and an image server 5, which are connected to the Internet and They are connected to each other through a network 6 constituted by a LAN or the like so as to be able to perform data communication with each other.

  The modalities 1 and 2 are composed of, for example, an X-ray diagnostic apparatus, an X-ray computed tomography apparatus (CT), a magnetic resonance imaging apparatus (MRI), an ultrasonic diagnostic apparatus, a gamma camera, SPECT, PET, CR, etc. A patient is taken to generate a medical image. This medical image includes patient information (patient name, patient ID, gender, age, address, etc.) and examination conditions (examination date, examination time, examination part, imaging (examination) person, modality type, Attached information such as inspection information indicating the name of the imaging apparatus (model name of the modality), accession number (inspection acceptance number), etc. is attached.

  Here, the number of modalities is not limited to the two shown in FIG. That is, one unit or three or more units may be used.

  RIS3 is a computer system that efficiently carries out work in the radiology department, and covers a wide variety of areas such as inspection order generation, reception work, inspection request, recording and transfer of inspection accounting information, inventory management of consumables including film, etc. Computerize business.

  The image inspection device 4 is a computer configured to be able to execute image detection processing on medical images generated by modalities 1 and 2. The image inspection process includes correction of the density (gradation) of the medical image, correction of the image such as the orientation of the patient in the medical image, the imprint of the left and right marks, and the orientation of the film (front and back). Correction of patient information such as patient name, patient ID, sex, address, etc. and examination information such as examination type and modality type at the time of examination.

  The image server 5 stores the medical image subjected to the image inspection process by the image inspection device 4 together with the accompanying information. When a medical image viewing request is made from an unillustrated interpretation device (image viewer), the image server 5 transmits the medical image to the requested interpretation device.

  FIG. 2 is a block diagram showing an internal configuration of the image inspection device 4 as an example of a medical information display device. Note that the detailed configurations of the modalities 1, 2, RIS 3, and image server 5 may be the same as those in the prior art, and are different from the essence of the present embodiment, so that the description thereof is omitted here.

  The image inspection apparatus 4 according to the present embodiment includes the number of medical images actually captured by the modalities 2 and 3 at the time of inspection in addition to the above-described image inspection processing (the number of actual images) and the inspection generated in the RIS 3. A process of comparing the planned number of shots, which is information included in the order, and presenting the result to the examiner of the image sensing device 4 is performed. The imaging device 4 includes a control unit 41, a medical image acquisition unit 42, a scheduled number of images information acquisition unit 43, a storage unit 44, an operation unit 45, and a display unit 46.

  The control unit 41 performs overall control related to the image inspection device 4. Further, the control unit 41 also has functions as a photographed number information acquisition unit 41a, a comparison unit 41b, an image inspection processing unit 41c, and a statistical information generation unit 41d.

  The number-of-photographing-image information acquisition unit 41a counts the number of medical images acquired through the medical image acquisition unit 42 (the number of medical images captured in series in one examination) to acquire the number of images to be captured. The series is a minimum unit group in the Digital Imaging and Communications in Medicine (DICOM) standard, and is a group of medical images divided according to various conditions such as each body part taken, image generation time, presence or absence of a contrast medium, and the like. That is. The number of shots may be sent from modalities 1 and 2.

  The comparison unit 41b compares the number of shots acquired via the number-of-shots information acquisition unit 41a with the number of shots acquired via the scheduled number-of-shoots information acquisition unit 43 from the RIS3, and there is a difference in the number of shots. It is determined whether or not. The image inspection processing unit 41c executes image inspection processing on the medical images transmitted from the modalities 1 and 2 in accordance with the operation of the operation unit 45 by the image examiner. The statistical information generation unit 41d determines the actual shooting from the comparison result between the actual number of shots acquired via the number-of-shots information acquisition unit 41a and the planned number of shots acquired from the RIS3 via the planned number of shots acquisition unit 43. Statistical information (details will be described later) regarding the difference between the number of shots and the number of shots to be taken is generated.

  The medical image acquisition unit 42 inputs the medical image transmitted from the modalities 1 and 2 via the network 6 to the control unit 41. The scheduled shooting number information acquisition unit 43 inputs the scheduled shooting number transmitted from the modalities 1 and 2 via the network 6 to the control unit 41.

  The storage unit 44 stores various data such as medical images transmitted from the modalities 1 and 2 via the network 6 and parameters (patient information and examination conditions) recorded in incidental information attached to the medical images. The operation unit 45 is an operation unit for the image examiner to operate the image detection device 4 and includes, for example, a keyboard and a mouse. The display unit 46 displays various medical information in addition to displaying a medical image at the time of the image inspection process.

  Hereinafter, the operation of the imaging device 4 shown in FIG. 2 will be described. FIG. 3 is a flowchart showing the image detection process in the image detection apparatus 4 according to the present embodiment. First, in the modalities 1 and 2, a specific part of the subject is imaged, and a medical image is generated. Accompanying information including the patient information and examination information described above is attached to the medical image. The medical image to which the supplementary information is attached is transmitted to the image examination apparatus 4 via the network 6 for each examination.

  In FIG. 3, when the medical image transmitted from the modality 1 or 2 and its supplementary information are received via the medical image acquisition unit 42, the control unit 41 stores the received medical image and its supplementary information. Stored in the unit 44 (step S1). Thereafter, the control unit 41 reads parameters (patient information, examination information, etc.) recorded in the supplementary information attached to the medical image (step S2), and an examination list as shown in FIG. 4 based on the loaded parameters. Is displayed on the display unit 46 (step S3).

  FIG. 4 is a diagram illustrating a display example of an examination list. In the examination list shown in FIG. 4, examination information (examination date, modality type, imaging apparatus name, etc.) is displayed in a list for each patient. At the time of an image inspection process described later, the image examiner operates the operation unit 45 to select an arbitrary inspection from the inspections displayed in a list as shown in FIG. When the examination is selected, the medical images taken in the examination are displayed in series units. The image examiner can perform image inspection while viewing the medical image.

  Here, in the present embodiment, when the examination list is displayed, the number of medical images actually taken with the modality 1 or 2 at the time of examination (actual number of photographs) is included in the examination order generated in the RIS3. Information on the number of scheduled images to be taken is also displayed, and an alert is displayed for examinations that have a difference in these numbers. The following steps S4 to S7 are processes for displaying this alert.

  After reading the parameters recorded in the supplementary information or in parallel with reading the parameters, the control unit 41 sends the number of medical images transmitted from the modality 1 or 2 by the imaging number information acquisition unit 41a in the examination unit. Are counted in series units to obtain the actual number of shots (step S4). Further, the control unit 41 uses the scheduled imaging number information acquisition unit 43 to request the RIS3 to acquire the scheduled imaging number and acquires the scheduled imaging number from the RIS3 (step S5).

  After acquiring the actual number of shots and the number of scheduled shots, the control unit 41 compares the actual number of shots with the number of planned shots by using the comparison unit 41b, and determines whether the actual number of shots and the number of planned shots are the same ( Step S6). If it is determined in step S6 that the actual number of shots does not match the scheduled number of shots, the control unit 41 matches the actual number of shots and the scheduled number of shots in the inspection list displayed on the display unit 46. An alert is displayed for an unexamined test as shown in FIG. 4 (step S7). Further, when it is determined in step S6 that the actual number of shots matches the scheduled number of shots, the control unit 41 skips the process of step S7.

  Here, alert display will be described. In the example of FIG. 4, a display column 100 for alert display is provided on the inspection list, and the display column 100 is displayed in a predetermined color (for example, for an inspection in which the actual number of shots does not match the scheduled number of shots). (Red). The alert display shown in FIG. 4 is an example and can be changed as appropriate. For example, as an alert display, each item of the relevant examination on the examination list may be displayed blinking.

  After step S6 or step S7, the control unit 41 determines whether any inspection on the inspection list shown in FIG. 4 is selected by the operation of the operation unit 45 of the image examiner (step S8). When the inspection is selected in the determination in step S8, the control unit 41 executes an image inspection process for the selected inspection (step S9). That is, when any one of the examinations on the examination list shown in FIG. 4 is selected, the control unit 41 reads the medical image related to the selected examination from the storage unit 44 and displays it on the display unit 46, and thereafter Then, the image detection process as described above is performed in accordance with the operation of the image examiner. After the completion of the image inspection process, the process proceeds to step S10. Further, in the determination in step S8, when the inspection is not selected, the process in step S9 is skipped and the process proceeds to step S10.

  After step S8 or step S9, the control unit 41 determines whether the statistical display button 101 indicated by reference numeral 101 in FIG. It is determined whether or not an instruction to display statistical information on the difference from the planned number of images has been taken (step S10). If it is determined in step S10 that an instruction to display statistical information on the difference between the actual number of shots and the planned number of shots has not been given, the process proceeds to step S13. On the other hand, in the determination of step S10, when an instruction to display statistical information on the difference between the actual number of shots and the planned number of shots is given, the imager is prompted to input statistical conditions (step S11). Here, the statistical condition is a condition for setting whether to display statistical information on the difference between the actual number of shots and the number of scheduled shots for each photographing apparatus, for each photographer, for each examination date, and for each modality type. It is. When statistical conditions are input by the examiner after step S11, the control unit 41 generates statistical information corresponding to the input statistical conditions by the statistical information generation unit 41d and causes the display unit 46 to display the statistical information. (Step S12). Thereafter, the process proceeds to step S13. After step S10 or step S13, the control unit 41 determines whether or not to end the process in FIG. 3 by determining whether or not the end button indicated by reference numeral 102 in FIG. 4 has been pressed (step S13). If it is determined in step S13 that the end button 102 has not been pressed, the process returns to step S8. On the other hand, when the end button 102 is pressed, the control unit 41 ends the process of FIG.

  Fig.5 (a)-FIG.5 (d) are figures which show the example of a display of statistical information. Here, FIG. 5A shows a display example in the case of displaying statistical information regarding the difference between the actual number of shots and the number of planned shots for each photographing apparatus in a tabular form, and FIG. 5B shows the actual information for each photographer. FIG. 5C shows a display example when the statistical information regarding the difference between the number of shots and the planned number of shots is displayed in a table format. FIG. 5C shows the statistical information regarding the difference between the actual number of shots and the number of planned shots for each modality type. FIG. 5D shows a display example when the statistical information regarding the difference between the actual number of shots and the number of shots for each examination date is displayed in a table format. “Frequency” in each figure is the total of the number of times that there is a difference between the actual number of shots and the planned number of shots for each statistical condition in the examination displayed on the examination list. Further, “cumulative frequency” is an accumulated value in a certain period (for example, one week, one month, one year, etc.). “Average” is a value obtained by dividing “cumulative frequency” by the cumulative period. These “frequency”, “cumulative frequency”, and “average” are aggregated for each statistical condition input by the examiner, and are displayed as shown in FIGS. 5 (a) to 5 (d).

  Here, the example of FIGS. 5A to 5D shows an example in which the statistical information is displayed in a table format, but the display format of the statistical information is not limited to the table format. For example, FIG. 6 shows a display example in the case where the statistical information regarding the difference between the actual number of shots and the number of planned shots for each photographing apparatus is displayed in a graph format. The statistical information is displayed in such a graph format. Also good.

  As described above, according to the present embodiment, when the examination list is displayed, the actual number of shots and the number of planned shots are displayed, and the difference between the number of actual shots and the number of planned shots is automatically calculated. Since the alert display is performed for the inspection having a difference in the number of images, the image examiner can collectively refer to the difference between the actual number of shots and the number of planned shots.

  Further, by displaying the statistical information, it is possible to compare the difference between the actual number of shots and the scheduled number of shots for each photographing apparatus, for each photographer, for each examination date, and for each modality type.

  Here, in the above-described embodiment, the information regarding the difference between the actual number of shots and the scheduled number of shots calculated in the image sensing device can be referred to only by the image sensing device 4. And the statistical information thereof may be transmitted from the imaging device 4 to the RIS 3 so that the information on the difference between the number of shots and the number of shots and the statistical information can be referred to in the RIS 3. Further, the functions of the comparison unit 41b and the statistical information generation unit 41d shown in FIG. 2 are provided in the RIS3, and information on the actual number of shots is transmitted from the modalities 1 and 2 to the RIS3. Information on the difference between the number of shots and the number of scheduled shots and statistical information thereof may be generated. In this case, RIS3 can be said to be a medical image display device according to an embodiment of the present invention.

  In the above example, the statistical information is displayed and output on the display unit 46, but may be output on a paper medium or the like. In this case, a printer is required in the image detecting device 4.
