  As is well known, the radiation imaging system 10 includes a radiation source 15 that irradiates radiation (for example, X-rays) toward a patient P to be imaged, a tube voltage applied to the radiation source 15, a tube current, and a radiation irradiation time. The radiation source controller 16 that controls the driving of the radiation source 15 according to the imaging conditions, and the radiation that is emitted from the radiation source 15 and transmitted through the patient P, and corresponds to a medical image. The radiographic image detection apparatus 17 which detects the image 26 (refer FIG. 3) and the console 18 which performs drive control of the radiographic image detection apparatus 17 are provided. In FIG. 1, only one radiation imaging system 10 is illustrated, but actually, a plurality of radiation imaging systems 10 are provided in a plurality of imaging rooms.

  The PACS 11, the client terminal 12, and the failed image management server 13 are configured by installing a control program such as an operating system and various application programs based on a computer such as a personal computer, a server computer, and a workstation.

  The PACS 11 has an image database (hereinafter abbreviated as DB (Data Base)) 20. A diagnostic image file (see FIG. 3) is stored in the image DB 20 so as to be searchable. The PACS 11 stores and manages diagnostic image files.

  The failed image management server 13 has a failed case DB 21. In the failure case DB 21, a diagnostic image file and a failure image file (see FIG. 3) are stored so as to be searchable. The failed image management server 13 stores and manages the diagnostic image file and the failed image file.

  The diagnostic image file is an image file created based on a diagnostic image that can be used for diagnosis among the radiographic images 26 captured by the radiation imaging system 10. On the other hand, the failed image file is an image file created based on a failed image that has failed to be photographed among the radiation images 26 photographed by the radiation imaging system 10. Note that causes of imaging failure include mispositioning of the patient P, body movement of the patient P, an imaging condition setting error, and the like.

  The client terminal 12 is operated by a medical staff when a plurality of medical staff members such as radiographers who are in charge of radiographing meet to conduct a conference for examining improvements in radiography. Conferences are held regularly, such as every month. In FIG. 1, only one client terminal 12 is depicted. However, for example, a plurality of client terminals 12 may be provided for each medical staff.

  In FIG. 2, the console 18 receives an imaging order for instructing medical staff to perform imaging. The imaging order is issued through a medical record by a doctor in a medical department such as internal medicine or surgery, and is transmitted to the console 18 via a radiation information system (RIS; Radiology Information System, not shown). The console 18 displays the contents of the photographing menu to medical staff. Note that the imaging order may be handed over to a medical staff from a doctor in the medical department instead of via a system such as RIS. In this case, the imaging order is manually input to the console 18 by the medical staff.

  The imaging order has items of order ID (Identification data), requested department, staff ID, patient ID, and imaging region / posture / direction. The order ID is a symbol or number for identifying each photographing order, and is automatically assigned by RIS. The name of the department that issued the imaging order is displayed in the requested department item, the staff ID of the doctor who is the imaging client who issued the imaging order is displayed in the staff ID item, and the patient to be imaged in the patient ID item Each patient ID of P is marked. The staff ID is a symbol or number for identifying an individual medical staff such as a doctor or a radiographer, and the patient ID is a symbol or number for identifying an individual patient.

  In the item of imaging part / posture / direction, the imaging part, posture, and imaging direction designated by the doctor who issued the imaging order are recorded. The imaging region is a region of the human body such as the head, cervical vertebra, chest, abdomen, hand, finger, elbow, and knee. The posture is the posture of the patient P such as standing, lying, and sitting, and the imaging direction is the direction of the patient P with respect to radiation such as the front, side, and back. FIG. 2 illustrates a case where the chest is set as the imaging region, the standing position is set as the posture, and the front is specified as the imaging direction. In addition to these items, items such as the date and time when the imaging order was accepted by RIS, the purpose of imaging such as follow-up after surgery and the determination of the effect of therapeutic agents, and items to be handed over from the doctor in the clinical department to the radiation technician, etc. May be.

  There may be one imaging order for one patient, or a plurality of imaging orders may be issued simultaneously for one patient. When a plurality of imaging orders are issued simultaneously for one patient, an identification code indicating that the imaging is for one patient is attached to the order IDs of the plurality of imaging orders.

  The console 18 stores a menu / condition table 25. In the menu / condition table 25, an imaging menu having a set of imaging region, posture, and imaging direction and imaging conditions corresponding to the imaging menu are registered in association with each other. The console 18 displays the contents of the menu / condition table 25 to the medical staff in a form in which an imaging menu can be set. In addition, a shooting menu corresponding to special shooting such as tomosynthesis shooting and long shooting may be provided as well as a shooting menu in which the shooting part and shooting direction excluding the posture are set as one set from the above shooting menu.

  The medical staff confirms the contents of the imaging order on the console 18, and selects and sets an imaging menu that matches the imaging region / posture / direction specified by the imaging order. Then, the imaging conditions that are the same as the imaging conditions corresponding to the set imaging menu, or the imaging conditions that finely adjust the imaging conditions corresponding to the set imaging menu according to the physique of the patient P, etc. are manually input to the radiation source control device 16. Set.

  After setting the imaging conditions, the medical staff positions the radiation source 15, the radiation image detection device 17, and the patient P to desired positions, and then drives the radiation source 15 to irradiate the patient P with radiation. The radiation that has passed through the patient P is applied to the radiation image detection device 17, whereby the radiation image detection device 17 detects the radiation image 26.

  In FIG. 3, the radiation image detection device 17 transmits a radiation image 26 to the console 18. The console 18 displays the radiation image 26 to medical staff. The medical staff determines whether the radiation image 26 displayed on the console 18 is a diagnostic image or a failed image, and inputs the result to the console 18. When the medical staff determines that the radiographic image 26 is a diagnostic image, this is a signal for the end of imaging for one imaging order.

  The console 18 creates an image file in which the radiation image 26 is associated with the imaging menu set when the radiographic image 26 is captured and other incidental information. As described above, there are two types of image files: a diagnostic image file based on a diagnostic image and a failed image file based on a failed image. The console 18 transmits the diagnostic image file to the PACS 11 and the diagnostic image file and the failed image file to the failed image management server 13. Note that the transmission timing of each image file by the console 18 may be transmitted immediately after the creation of each image file, or a failed image file is not necessary for diagnosis. Stock may be sent and transmitted at a fixed timing such as when a day's work is completed and shut down.

  In FIG. 4, the image file has a file format conforming to the DICOM (Digital Imaging and Communication in Medicine) standard, for example, and includes an additional information storage area 27 in which incidental information is stored, and an image storage area in which a radiation image 26 is stored. 28.

  The file ID is a symbol or number for identifying each image file, and is automatically assigned by the console 18 when the image file is created. The photographing date and time is literally the date and time when the photographing was performed, and is automatically given by the radiation image detection device 17 when the radiation image 26 is detected.

  In each item of patient ID, patient name, sex, date of birth, age, height, weight, hospitalization / outpatient classification, the patient ID of the patient P to be imaged, etc. are described. Information about these patients P can be obtained from, for example, a hospital information system (HIS; Hospital Information System, not shown). In addition to the above, an item of a body mass index such as a BMI (Body Mass Index) index calculated from height and weight may be added.

  In the item of order ID, the order ID of the photographing order to be photographed is written. The same order ID is written in the item of order ID until the medical staff determines that the radiographic image 26 is a diagnostic image and there is a sign of completion of imaging. That is, when a failed image is captured due to a failure in photographing, at least one failed image file having the same order ID and one diagnostic image file are created. The number of failed image files in which the same order ID is written indicates the number of times of failure in photographing with the order ID, that is, the number of failed images.

  The shooting menu item includes a shooting menu set by the medical staff, and the tube voltage, tube current, and irradiation time items include the tube voltage, tube current, and irradiation time set in the radiation source controller 16 by the medical staff, respectively.

The failed image management program 70 is an application program for causing a computer constituting the failed image management server 13 to function as a failed image management apparatus, and corresponds to an operation program.

  When the failed image management program 70 is activated, the CPU 37B of the failed image management server 13 cooperates with the memory 36 to accept the receiving unit 71, the first calculating unit 72, the first extracting unit 73, and the second extracting unit. 74, a second calculation unit 75, a screen output control unit 76, and a read / write (hereinafter abbreviated as R (Read) / W (Write)) control unit 77.

  The accepting unit 71 accepts a distribution request from the client terminal 12. The receiving unit 71 outputs information on the current staff ID of the designation information included in the distribution request to the first calculation unit 72 and information on the number of cases to the first extraction unit 73. In addition, the reception unit 71 outputs the information on the number of sheets and the extraction target period to the second extraction unit 74, and the information on the current staff ID and the narrowing-down condition to the second calculation unit 75. Furthermore, the reception unit 71 outputs information on the staff ID this time to the screen output control unit 76 and the R / W control unit 77, respectively.

  The first calculation unit 72 is a first index value that quantitatively represents a failure situation for each shooting menu based on the diagnostic image file stored in the failure case DB 21 and the shooting menu recorded in the failure image file. Is calculated. The first extraction unit 73 automatically extracts the target menu based on the first index value.

  The second extraction unit 74 extracts a failed image file in which the target menu extracted by the first extraction unit 73 is described from a plurality of failed image files stored in the failure example DB 21. The second calculation unit 75 calculates a second index value that quantitatively represents the priority when the study image 26C is used for viewing by the participant.

  The screen output control unit 76 generates the conference screen 30 based on the target menu extracted by the first extraction unit 73, the failed image file extracted by the second extraction unit 74, and the like. The screen output control unit 76 outputs the generated XML data of the conference screen 30 to the client terminal 12 that is the output source of the distribution request.

  The R / W control unit 77 controls writing and reading of the conference history information 78 stored in the storage device 35B. The R / W control unit 77 outputs the conference history information 78 to the first calculation unit 72.

  The conference history information 78 is information representing the history of the conference held last time. Specifically, as shown in FIG. 11, the conference history information 78 is composed of summary data 78A representing the summary of the previous conference and copy loss count data 78B. The summary data 78A includes the date of the previous conference, the staff ID of the participant of the previous conference (hereinafter referred to as the previous staff ID), and the target menu (hereinafter referred to as the following menu) extracted by the first extraction unit 73 at the previous conference. The previous target menu) is written. The number-of-shots data 78 </ b> B describes the number of times of shooting-by-photographing menu (hereinafter referred to as the number of times of previous copying) for the period from the day after the previous conference date to the date of the previous conference.

  In FIG. 11, “2015.02.27” is the date of the last conference, “R0001, R0004, R0007, R0008” is the last staff ID, and “chest / standing / front, chest / standing is the last target menu. "/ Back" is illustrated. Further, as the number of previous image loss, “15” in the shooting menu “chest / standing / front”, “30” in the shooting menu “chest / standing / back”, and the like are illustrated.

  In FIG. 12, the first calculation unit 72 outputs a search command specifying the period and the failure flag “1” (failure image file) to the failure case DB 21. In the period specified by the search command in this case, the receiving unit 71 receives a distribution request from the next day of the previous conference date recorded in the summary data 78A of the conference history information 78 from the R / W control unit 77. That is, the period until the date of this conference (hereinafter referred to as the previous-this period). In response to a search command from the first calculation unit 72, the failure example DB 21 searches for a failed image file in which the shooting date and time within the previous-current period is recorded, and the search result 80 is stored in the first calculation unit 72. Output.

  If the conference history information 78 is not stored in the storage device 35B at the first conference this time, all the failed image files in the failure example DB 21 are stored as search results 80 from the failure case DB 21. 1 is output to the calculation unit 72.

  In FIG. 12, as the previous-current period, from “2015.02.28” the day after the previous conference date “2015.02.27” in FIG. "Is exemplified. Therefore, the search result 80 is composed of a failed image file in which the shooting date and time within the previous-current period of “2015.02.28 to 2015.03.27” is written.

  In FIG. 13, the first calculation unit 72 creates intermediate processing data 81 based on the search result 80. Specifically, the first calculation unit 72 pays attention to the shooting menu of the failed image file of the search result 80, and counts the number of shooting failures for each shooting menu based on the number of failed image files for each shooting menu. . For example, in the case of the shooting menu “chest / standing position / front”, “40” is counted as the number of image loss. The number of lost images thus counted is the number of lost images for each shooting menu that occurred between the previous and current time periods (hereinafter referred to as the current number of lost images). After counting the number of times of image loss this time, the first calculation unit 72 outputs the intermediate processing data 81 to the R / W control unit 77.

  In FIG. 14, the first calculation unit 72 further creates intermediate processing data 82 based on the conference history information 78 from the R / W control unit 77 and the intermediate processing data 81. Specifically, the first calculation unit 72 registers the previous number of times of failure from the number-of-failures data 78 </ b> B of the conference history information 78 and the current number of times of failure from the intermediate processing data 81 in the intermediate processing data 82. Then, for each shooting menu, an increase / decrease is calculated by subtracting the previous number of failures from the current number of failures, and an increase rate is calculated by dividing this increase / decrease by the previous number of failures.

  For example, in the case of the shooting menu “Chest / Standing / Front”, the number of previous shots is “15”, the current number of shots is “40”, and the increase / decrease is 40-15 and “25”. Is 25/15 × 100≈167 and becomes “167%”. In the case of the shooting menu “abdomen / standing position / back”, the previous number of shots is “36”, the number of times of the current shot is “25”, and the increase / decrease is 25-36 and “−11”. Becomes −31% when −11 / 36 × 100≈−31.

  Subsequently, the first calculation unit 72 derives the variable X1 based on the increase rate of the number of times of shooting for each shooting menu based on the increase rate / variable table 84.

  The increase rate / variable table 84 is a data table in which variables corresponding to the increase rate are registered, and is stored in, for example, the storage device 35B. Here, the variable “10” for an increase rate of 100% or more, the variable “9” for an increase rate of 90% or more and less than 100%, and the variable “2” for an increase rate of 20% or more and less than 30%. In addition, a variable obtained by subtracting one by one from “10” in increments of 10% from an increase rate of 100% is registered, such as a variable “1” for an increase rate of 10% to less than 20%. A variable “0” is registered for an increase rate of less than 10%.

  For example, in the case of the shooting menu “chest / standing position / front”, the increase rate is “167%”, which is 100% or more, so “10” is derived as the variable X1 and registered in the intermediate processing data 82. In the case of the shooting menu “abdomen / standing position / back side”, the increase rate is “−31%”, which is less than 10%, and therefore “0” is derived as the variable X1 and registered in the intermediate processing data 82.

  The first calculation unit 72 also derives a variable X2 based on the rate of increase in the number of times of copying of the previous target menu in the summary data 78A of the conference history information 78 based on the increase rate / variable table 84. The first calculator 72 derives the variable X2 only for the shooting menu corresponding to the previous target menu among the shooting menus. The method for deriving the variable X2 is the same as that for the variable X1.

  FIG. 14 illustrates the same “chest / standing position / front, chest / standing position / back” as the previous target menu in FIG. 11. The same “10” as the variable X1 is derived and registered in the intermediate processing data 82 as the variable X2 of the shooting menu “chest / standing position / front” corresponding to the previous target menu. Also, “3”, which is the same as the variable X1, is derived and registered in the intermediate processing data 82 for the variable X2 of the photographing menu “chest / standing position / back”. For the shooting menus “abdomen / standing position / front” and “abdomen / standing position / back” that do not correspond to the previous target menu, the variable X2 is not derived and registered, as indicated by the hatched lines.

  Furthermore, the first calculation unit 72 also derives a variable X3 related to the shooting menu that was not extracted in the previous target menu. The first calculation unit 72 derives the variable X3 only for the shooting menu that does not correspond to the previous target menu among the shooting menus.

  In FIG. 14, “5” is uniformly registered as the variable X3 for the shooting menus “abdomen / standing position / front” and “abdomen / standing position / back” that do not correspond to the previous target menu. For the shooting menus “chest / standing / front” and “chest / standing / back” corresponding to the previous target menu, the variable X3 is not derived and registered, as indicated by the diagonal lines.

  In FIG. 15, the first calculation unit 72 receives information on the current staff ID from the reception unit 71. The first calculation unit 72 is based on the current staff ID information, the previous staff ID and the information on the previous target menu described in the summary data 78A of the conference history information 78 of the R / W control unit 77, and the search result 80. Intermediate processing data 83 is created.

  Specifically, the first calculation unit 72 pays attention to the shooting menu and the staff ID of the failed image file of the search result 80, and applies to both the shooting menu corresponding to the previous target menu and the previous staff ID and the current staff ID. Based on the number of failed image files in which existing staff IDs are recorded, the number of failed shooting menus corresponding to the previous target menu is counted.

  Participants with staff IDs in both the previous staff ID and the current staff ID are participants who have participated in the previous conference and are designated to participate in the current conference (hereinafter referred to as consecutive participants). is there. In addition, the number of times of loss counted in this way is the number of times that a continuous participant failed to shoot the shooting menu corresponding to the previous target menu during the previous-current time period.

  After counting the number of times of copying, the first calculation unit 72 derives a variable X4 based on whether or not the continuous participant has failed for the previous shooting of the target menu. Here, as the variable X4, a numerical value equal to the counted number of copying failures is derived. The first calculator 72 derives the variable X4 only for the shooting menu corresponding to the previous target menu among the shooting menus.

  15, the same staff IDs “R0001”, “R0002”, “R0005”, and “R0008” as in FIG. 9 are illustrated as the current staff ID. Also, as the previous staff ID, the same staff IDs “R0001”, “R0004”, “R0007”, and “R0008” as in FIG. 11 are used as the previous target menu “chest / standing position / front, chest / “Standing / back” is illustrated. The staff IDs that exist in both the previous staff ID and the current staff ID are “R0001” and “R0008”.

  Further, in FIG. 15, the three results of the search result 80 include “chest / standing / front” corresponding to the previous target menu in the shooting menu and “R0001” or “R0008” in the staff ID. An example of a case where there is one failed image file in which “chest / standing position / back” corresponding to the previous target menu exists in the shooting menu and “R0008” in the staff ID exists. Yes.

  In this case, “3” is set as the number of shooting failures in the item of the shooting menu “chest / standing position / front” of the intermediate processing data 83, and “number of shooting times” is set in the item of the shooting menu “chest / standing position / back”. 1 ”is registered. Also, “3” is derived as a variable X4 for the shooting menu “chest / standing / front”, and “1” is derived and registered as a variable X4 for the shooting menu “chest / standing / back”. . For the shooting menu that does not correspond to the previous target menu, no item is prepared in the intermediate processing data 83, and therefore the variable X4 is not derived and registered.

  In FIG. 16, the first calculation unit 72 reads each variable Xi (i = 1 to 4) from each intermediate processing data 82 and 83. The first calculator 72 calculates a first index value for each shooting menu by using a first calculation formula ΣXi that calculates the sum of these variables Xi. The first calculation unit 72 outputs the calculation result 86 of the first index value to the first extraction unit 73 and the screen output control unit 76.

  The first index value may be calculated after adding or multiplying each variable Xi with an appropriate weighting coefficient. For example, 10 is added to the variable X1 based on the rate of increase in the number of times of loss by shooting menu. Alternatively, the variable X4 based on whether or not the continuous participant has failed for the previous shooting of the target menu is multiplied by 2. In this case, the weighting coefficient may be configured to be changeable at the client terminal 12.

  In FIG. 17, the first extraction unit 73 receives the information on the number of cases from the reception unit 71 and the calculation result 86 of the first index value from the first calculation unit 72. The first extraction unit 73 extracts the target menus for the designated number of cases based on the calculation result 86.

  More specifically, the first extraction unit 73 creates intermediate processing data 90 in which the shooting menus are sorted in descending order of the first index value of the calculation result 86. Then, the target menu is sequentially extracted from the first shooting menu of the intermediate processing data 90, and the extraction is stopped when the extracted target menu reaches the designated number. The first extraction unit 73 outputs the target menu thus extracted to the second extraction unit 74, the screen output control unit 76, and the R / W control unit 77 as the extraction result 91.

  If the number of cases is not input on the designation screen 50 and there is no number of pieces of information in the designation information, for example, three shooting menus in the first to third places in the intermediate processing data 90 are extracted as target menus.

  In FIG. 17, “1” is designated as the number of cases, and the first shooting menu of the intermediate processing data 90 is “chest / standing / front”, so this first shooting menu “chest / standing / “Front” is extracted as the target menu.

  In FIG. 18, the second extraction unit 74 receives the extraction target period information from the reception unit 71 and the extraction result 91 of the target menu from the first extraction unit 73. The second extraction unit 74 outputs a search command specifying the same extraction period as the received extraction target period, the same shooting menu as the received target menu, and the failure flag “1” (failure image file) to the failure case DB 21. To do. In response to the search command from the second extraction unit 74, the failure example DB 21 searches for a failed image file in which the shooting date and time within the extraction target period and the same shooting menu as the target menu are written, and the search result 95 Is output to the second extraction unit 74. The second extraction unit 74 outputs the search result 95 to the second calculation unit 75.

  If the extraction target period is not input on the designation screen 50 and there is no information on the extraction target period in the designation information, all the failed image files in which the same shooting menu as the target menu in the failure example DB 21 is described. Is output as the search result 95 from the failure example DB 21 to the second extraction unit 74.

  In FIG. 18, “2015.02.28 to 2013.03.13”, which is the same as FIG. Further, as the target menu, the same “chest / standing position / front” as in FIG. 17 is illustrated. Therefore, the search result 95 is a failed image file in which the shooting date and time within the extraction target period “2015.02.28 to 2013.03.13” and the shooting menu of “chest / standing position / front” are recorded. Consists of.

  In FIG. 19, the second calculation unit 75 receives information on the current staff ID and information on narrowing-down conditions from the reception unit 71. Further, the second calculation unit 75 receives the search result 95 from the second extraction unit 74.

  The second calculation unit 75 creates intermediate processing data 98 based on the search result 95. Specifically, the second calculation unit 75 first derives a variable Y1 related to the participant by paying attention to the staff ID of the failed image file of the search result 95 and uses this as the file of the failed image file of the search result 95. Register for each ID. The variable Y1 is a variable according to whether or not a participant is associated with the failed image that is the examination image 26C.

  For a failed image file in which the same staff ID as the staff ID is recorded, that is, a failed image file based on a failed image taken by a participant of the current conference, “1” is set as the variable Y1. Derived. On the other hand, for a failed image file in which a staff ID different from the current staff ID is recorded, that is, a failed image file based on a failed image taken by a person other than the current conference participant, 0 "is derived.

  19, the same staff IDs “R0001”, “R0002”, “R0005”, and “R0008” as in FIG. 9 and the like are illustrated as the current staff ID. Further, since the current stuff IDs “R0001” and “R0002” are respectively described in the failed image files of the file IDs “F0110” and “F0115”, the file IDs of these failed image files of the intermediate processing data 98 are recorded. In the item, a variable Y1 “1” is registered.

  On the other hand, the failed image file with the file ID “F0250” has a staff ID “R0010” different from the current staff ID, so the item of the file ID “F0250” of the intermediate processing data 98 has a variable Y1 “ “0” is registered.

  Subsequently, the second calculation unit 75 derives variables Y2 to Y7 related to the narrowing condition by focusing on the items specified by the narrowing condition among the incidental information of the failed image file of the search result 95, and these are derived as file IDs. Register every time. The variable Y2 corresponds to the age, the variable Y3 corresponds to the gender, the variable Y4 corresponds to the inpatient / outpatient classification, the variable Y5 corresponds to the time zone, the variable Y6 corresponds to the day of the week, and the variable Y7 corresponds to each narrowing-down condition of the radiographing room.

  “1” is derived as the variables Y2 to Y7 for the failed image file in which the incidental information matching the narrowing-down condition is written. On the other hand, “0” is derived as variables Y2 to Y7 for a failed image file in which incidental information different from the narrowing-down conditions is written.

  Note that the second calculation unit 75 derives only the variables corresponding to the narrowing-down conditions from the reception unit 71 among the variables Y2 to Y7, and does not derive the other variables as indicated by hatching. In addition, when the narrowing condition is not selected on the designation screen 50 and there is no narrowing condition information in the designation information, the second calculation unit 75 derives only the variable Y1 without deriving the variables Y2 to Y7.

  In FIG. 19, the same sex “male” and hospitalization / outpatient classification “outpatient” as in FIG. Then, in the failed image file with the file ID “F0110”, the sex “male” and the inpatient / outpatient classification “outpatient” that match the filtering condition from the reception unit 71 are described. In the item of ID “F0110”, a variable Y3 “1” and a variable Y4 “1” are registered.

  On the other hand, in the failed image file with the file ID “F0250”, the sex “female” and the hospitalization / outpatient classification “hospitalization” different from the narrowing-down conditions from the reception unit 71 are described. In the item “F0250”, “0” is registered for both the variables Y3 and Y4.

  In FIG. 20, the second calculation unit 75 reads each variable Yj (j = 1 to 7) from the intermediate processing data 98. The second calculator 75 calculates a second index value for each failed image file by using a second calculation formula ΣYj for calculating the sum of these variables Yj. The second calculator 75 outputs the second index value calculation result 99 to the second extractor 74 and the screen output controller 76. As in the case of the first index value, the second index value may be calculated by adding or multiplying each variable Yj with a weighting coefficient, or the weighting coefficient may be set and changed at the client terminal 12. Good.

  In FIG. 21, the second extraction unit 74 receives the number information from the reception unit 71 and the calculation result 99 of the second index value from the second calculation unit 75. Based on the calculation result 99, the second extraction unit 74 extracts a designated number of failed image files (failed images to be considered images 26C).

  More specifically, the second extraction unit 74 creates the intermediate processing data 103 in which the file IDs of the failed image files of the search result 95 are sorted in descending order of the second index value of the calculation result 99. The second extraction unit 74 registers the file IDs of the failed image files having the same second index value in the same order, and assigns serial numbers in ascending order of the file ID numbers. Then, the failed image files having the file ID of the serial number “1” in the intermediate processing data 103 are extracted in order, and the extraction is stopped when the number of extracted failed image files reaches the designated number. The second extraction unit 74 outputs the failed image file thus extracted to the screen output control unit 76 as the extraction result 104.

  If the number is not entered on the designation screen 50 and the number information is not included in the designation information, for example, ten failed image files with serial numbers “1” to “10” are extracted. If the number of failed image files in the search result 95 is less than the designated number, all the failed image files in the search result 95 are extracted regardless of the second index value.

  In FIG. 21, “50” is designated as the number of sheets, the file ID “F0110” is assigned to the serial number “1” of the intermediate processing data 103, the file ID “F0113” is assigned to the serial number “2”, and the serial number “49”. Since the file ID “F0195” is registered in the serial number “50” and the file ID “F0200” is registered in the serial number “50”, the failed image files having the file IDs “F0110”, “F0113”,..., “F0195”, “F0200” are registered. Has been extracted.

  In FIG. 22, after extracting the failed image file, the second extraction unit 74 searches for a diagnostic image as the reference image 26R (see FIG. 27). Specifically, the second extraction unit 74 specifies the same shooting menu as the target menu, the same patient ID as the failed image file of the extraction result 104, and a search command specifying the failed flag “0” (diagnostic image file). Are output to the copy failure case DB 21. In accordance with the search command from the second extraction unit 74, the failure example DB 21 stores the same shooting menu as the target menu including the diagnostic image file in which the same patient ID as the failure image file of the extraction result 104 is written. The obtained diagnostic image file is searched, and the search result 105 is output to the second extraction unit 74. The second extraction unit 74 outputs the search result 105 to the screen output control unit 76. Note that the order ID may be specified by the search command instead of the patient ID.

  In FIG. 22, the same target menu “chest / standing position / front” as in FIG. For this reason, the search result 105 includes a diagnostic image file in which a shooting menu of “chest / standing / front” is written. Further, “P0050”, “P0070” and the like are exemplified as the patient ID of the failed image file of the extraction result 104. Therefore, in the search result 105, a diagnostic image file in which patient IDs such as “P0050” and “P0070” are written, and a diagnostic image in which other patient IDs “P0060”, “P0150”, and the like are written. Files are mixed.

  In FIG. 23, the screen output control unit 76 extracts the current staff ID information from the reception unit 71, the first index value calculation result 86 from the first calculation unit 72, and the target menu extraction from the first extraction unit 73. The result 91 is accepted. In addition, the screen output control unit 76 calculates the second index value calculation result 99 from the second calculation unit 75, the failed image file extraction result 104 from the second extraction unit 74, and the diagnostic image file search result 105. Accept. The screen output control unit 76 generates the conference screen 30 based on the current staff ID information, the calculation results 86 and 99, the extraction results 91 and 104, and the search result 105.

  More specifically, the screen output control unit 76 displays information on participants in the current conference on the conference screen 30 based on the information on the current staff ID. Further, the screen output control unit 76 displays the target menu on the conference screen 30 based on the extraction result 91.

  Further, the screen output control unit 76 displays the examination image 26 </ b> C on the conference screen 30 based on the extraction result 104 and the reference image 26 </ b> R based on the search result 105. The examination image 26 </ b> C is a radiation image 26 (failure image) stored in the image storage area 28 of the failure image file of the extraction result 104. The reference image 26 </ b> R is a radiation image 26 (diagnosis image) stored in the image storage area 28 of the diagnostic image file of the search result 105.

  When there are a plurality of target menus extracted by the first extraction unit 73, the screen output control unit 76 displays the target menus in an arrangement according to the first index value of the calculation result 86 on the conference screen 30. In addition, when there are a plurality of failed image files extracted by the second extraction unit 74, that is, when there are a plurality of examination images 26C, the screen output control unit 76 displays the second index value of the calculation result 99 on the conference screen 30. The examination images 26C are displayed in an arrangement according to the above.

  In FIG. 24, the R / W control unit 77 includes information on the current staff ID from the reception unit 71, intermediate processing data 81 regarding the number of current copying failures from the first calculation unit 72, and a target menu from the first extraction unit 73. The extraction result 91 is received. The R / W control unit 77 updates the conference history information 78 based on the current staff ID information, the intermediate processing data 81, and the extraction result 91.

  Specifically, the R / W control unit 77 receives the previous staff ID on the day when the reception request is received by the reception unit 71 for the date of the previous conference in the overview data 78A, that is, the date of the current conference. For the current staff ID from 71, the previous target menu is rewritten to the target menu of the extraction result 91, respectively. Further, the R / W control unit 77 replaces the copy loss number data 78 </ b> B with the intermediate processing data 81.

  In FIG. 25 showing the conference screen 30 in the initial display state, the conference screen 30 includes a target menu display area 110, a participant display area 111, a consideration image display area 112, a reference image display area 113, and a reference image candidate display area 114. Have.

  In the target menu display area 110, display is performed according to the current staff ID information, the first index value calculation result 86, and the target menu extraction result 91. The target menu display area 110 is divided into a display column 110A for icons 115 indicating individual participants and a display column 110B for target menus. The icon 115 in the display column 110A indicates that the examination image 26C taken by the participant indicated by the icon 115 exists in the examination image 26C extracted for the target menu in the display column 110B.

  The target menus in the display column 110B are arranged from the top in descending order of the first index value (in order of the first index value). An expansion button 116 is provided next to the target menu.

  In the participant display area 111, display according to the information of the staff ID this time is performed. In the participant display area 111, an icon 115 and the name of the participant are displayed. The icon 115 is the same as the display column 110A of the target menu display area 110, and its color and pattern are changed to distinguish individual participants as shown by hatching.

  FIG. 25 shows an example in which three target menus of “chest / standing / front”, “chest / standing / back”, and “abdomen / standing / front” are displayed in the display column 110B. In this case, the target menu “Chest / Standing / Front” in the top display order is the target menu having the largest first index value among the three target menus, and the target in the bottom display order. The menu “abdomen / standing position / front” is the target menu having the smallest first index value among the three target menus.

  In FIG. 25, the same four people as “Yamada Tadashi”, “Ichiro Kawamura”, “Misaki Oiwa”, and “Saika Hyakuyasu” are illustrated as participants. For example, in the display column 110A corresponding to the target menu “chest / standing / front” in the display column 110B, icons 115 of all four participants are displayed and extracted for the target menu “chest / standing / front”. It is shown that the examination image 26C photographed by four participants exists in the examination image 26C.

  In the examination image display area 112, display according to the current staff ID information and the extraction result 104 of the failed image file is performed. In the reference image display area 113 and the reference image candidate display area 114, display according to the search result 105 of the diagnostic image file is performed. In the initial display state of FIG. 25, these display areas 112 to 114 are blank as shown.

  In the upper part of the examination image display area 112, an information button 117 for displaying supplementary information associated with the examination image 26C and a memo button 118 for writing a memo such as a cause of copying or a participant's remarks are provided. ing. Further, similarly to the information button 117, an information button 119 for displaying supplementary information associated with the reference image 26R is provided above the reference image display area 113.

  In FIG. 26, when the development button 116 for a desired target menu in the display field 110 </ b> B is selected with the cursor 56, the examination image selection area 120 appears next to the target menu display area 110. The target menu for which the expand button 116 is selected can be changed in color or pattern to be distinguished from other target menus as shown by hatching. In this example, the top target menu “chest / standing / front” is selected.

  In the consideration image selection area 120, display is performed according to the current staff ID information, the second index value calculation result 99, and the extracted image file extraction result 104. The examination image selection area 120 is divided into a display field 120A for the icon 115 and a display field 120B for the thumbnail 121 of the examination image 26C. In addition, the examination image selection area 120 is provided with a scroll bar 122 for displaying a non-display icon 115 and a thumbnail 121.

  The icon 115 in the display column 120A indicates that the examination image 26C displayed by the thumbnail 121 in the display column 120B is taken by the participant indicated by the icon 115. In addition, the thumbnails 121 in the display column 120B are arranged in the descending order of the second index value (the order of the second index value is high).

  In FIG. 27, when the desired thumbnail 121 in the display field 120B is selected with the cursor 56, the display of the examination image selection area 120 disappears. Then, in the examination image display area 112, the examination image 26C in which the thumbnail 121 is selected by the cursor 56 and the icon 115 corresponding to the display column 120A corresponding to the examination image 26C are displayed. Of the icons 115 in the participant display area 111, the same icon 115 as the icon 115 displayed in the examination image display area 112 may be highlighted, for example.

  In addition, the reference image 26R is displayed in the reference image display area 113, and the candidate thumbnails 123 of the reference image 26R are displayed in the reference image candidate display area 114, respectively. The thumbnail 123 of the reference image candidate display area 114 is a patient to be imaged of the examination image 26C displayed in the examination image display area 112 among the reference images 26R associated with the same imaging menu as the object menu for which the development button 116 is selected. Are divided into a candidate for the upper reference image 26R associated with a different patient and a candidate for the lower reference image 26R associated with the same patient as the imaging target patient of the examination image 26C displayed in the examination image display area 112. Displayed. By selecting the thumbnail 123 with the cursor 56, the display of the reference image 26R in the reference image display area 113 can be switched. In addition, instead of the candidate of the reference image 26R associated with a patient different from the imaging target patient of the examination image 26C displayed in the examination image display area 112, the examination image display area 112 is arranged in the upper stage of the reference image candidate display area 114. A reference image 26R having the same imaging order as that of the examination image 26C displayed in (a diagnostic image obtained by re-imaging after the examination image 26C, which is a failed image), may be displayed.

  As shown in FIG. 28, when the information button 117 is selected with the cursor 56, the incidental information display area 124 appears on the examination image display area 112. In the incidental information display area 124, incidental information (file ID, imaging date / time, patient ID, order ID, tube voltage, tube current, irradiation time, etc.) associated with the examination image 26C is displayed. Although illustration is omitted, when the information button 119 is selected with the cursor 56, an additional information display area for displaying additional information associated with the reference image 26R appears on the reference image display area 113. When the memo button 118 is selected with the cursor 56, a text input box appears on the conference screen 30, and a memo can be written through the text input box. The written memo is associated with the examination image 26C and registered in the failure example DB 21.

  Hereinafter, the operation of the above configuration will be described with reference to the flowchart of FIG. First, when a conference is held, the medical staff operates the client terminal 12 to input a distribution instruction for the conference screen 30 via the designation screen 50. In response to this distribution instruction, the browser control unit 46 creates designation information. Then, as shown in step S <b> 100, a request for distributing the conference screen 30 including the designation information is issued from the browser control unit 46 to the failed image management server 13.

  On the designation screen 50, the number of extractions of the target menu, the number of extracted examination images 26C, and the extraction target period of the examination image 26C can be designated. As described above, since the number of items, the number of sheets, and the extraction target period can be specified, it is possible to perform a narrowed-down examination within a limited examination time.

  In the failed image management server 13, the distribution request is received by the receiving unit 71 (step S200). Information on the current staff ID of the designation information of the distribution request is sent to the first calculating section 72, information on the number of cases is sent to the first extracting section 73, information on the number of sheets and the extraction target period is sent to the second extracting section 74, the current staff ID, Information on the narrowing conditions is output to the second calculation unit 75, and information on the current staff ID is output to the screen output control unit 76 and the R / W control unit 77, respectively.

  The first calculation unit 72 calculates a first index value (step S210). The calculation result 86 of the first index value is output to the first extraction unit 73 and the screen output control unit 76.

  The first index value is calculated by a first calculation formula ΣXi having a variable X1 based on the rate of increase in the number of image loss for each shooting menu. For this reason, the first index value takes into account the rate of increase in the number of times of loss by shooting menu. Therefore, according to the first index value, it is possible to accurately grasp the copying situation of each shooting menu.

  In addition to the variable X1, the first calculation formula ΣXi also has a variable X2 based on the rate of increase in the number of times the previous target menu has been lost. For this reason, the first index value takes into consideration the copy status of the previous target menu in the previous-current period.

  The first calculation formula ΣXi also includes a variable X3 related to the shooting menu that was not extracted in the previous target menu. For this reason, the first index value takes into consideration a shooting menu that does not correspond to the previous target menu.

  Furthermore, the first calculation formula ΣXi also includes a variable X4 based on whether or not the continuous participant has failed for the previous shooting of the target menu. For this reason, the first index value also considers whether or not consecutive participants have failed in the shooting of the shooting menu corresponding to the previous target menu within the previous-current time period.

  The first extraction unit 73 extracts the target menus for the designated number of cases based on the calculation result 86 of the first index value (step S220). Specifically, the first menu value is extracted as the target menu in order from the shooting menu with the first rank, and the extraction is stopped when the target menu reaches the designated number. The extraction result 91 of the target menu thus extracted is output to the second extraction unit 74, the screen output control unit 76, and the R / W control unit 77.

  In the present embodiment, the first index value is the sum of the variables Xi as indicated by the first calculation formula ΣXi. Therefore, the higher the rate of increase in the number of times of copying and the greater each variable Xi, that is, the higher the rate of increase in the frequency of copying, the higher the first index value, and the rank of the first index value. Also gets higher. Therefore, a shooting menu with a relatively high rank of the first index value is a shooting menu with a relatively high rate of increase in the shooting loss frequency.

  In the present embodiment, since the shooting menu having a relatively high first index value order is automatically extracted as the target menu by the first extraction unit 73, a shooting menu having a relatively low rate of increase in the shooting failure frequency is extracted. There is no risk that a designated and unnecessary study will be performed, resulting in a loss of valuable time for the medical staff, and the medical staff can be surely examined to suppress an increase in the frequency of image loss.

  In addition, since the target menu is automatically extracted, the medical staff must accurately grasp the copy status of each shooting menu in order to extract and specify the shooting menu with a relatively high rate of increase in the copy loss frequency. There is no. For this reason, the burden on the medical staff can be reduced, and the medical staff can efficiently consider improvement points in imaging.

  If the rate of increase in the number of failed shots in the previous target menu extracted at the previous conference was relatively low at the current conference, the previous conference was considered meaningful and the shooting skill of the previous target menu was improved. However, if it is relatively high, it indicates that the previous conference was not considered and the shooting skill of the previous target menu has not yet improved.

  If the rate of increase in the number of failed shots for the previous target menu was relatively high at the current conference, the previous target menu was also extracted as the target menu at the current conference, and the shooting menu corresponding to the previous target menu was taken. It is preferable to browse the failed radiation image 26 as the examination image 26C because the examination can be continued from the previous conference and the improvement of the imaging can be reviewed.

  In the present embodiment, as described above, the state of failure of the previous target menu in the previous-current period is added to the first index value by the variable X2. For this reason, the first index value rank is higher in the previous target menu having a relatively high rate of increase in the number of times of copying, and the first extraction unit 73 is likely to be extracted as the target menu. Therefore, the probability that the radiographic image 26 that has failed in the shooting of the shooting menu corresponding to the previous target menu is used for browsing as the examination image 26C is increased.

  On the other hand, if the rate of increase in the number of failed shots for the previous target menu was relatively low at the current conference, the shooting menu that does not correspond to the previous target menu is selected as the target menu at the current conference. It is preferable that the extracted radiographic image 26 that has failed in the shooting of the shooting menu that does not correspond to the target menu last time is browsed as the examination image 26C because an increase in the shooting frequency can be suppressed on average in each shooting menu. .

  In the present embodiment, as described above, the shooting menu that does not correspond to the previous target menu is added to the first index value by the variable X3. For this reason, if the rate of increase in the number of times of loss of the previous target menu is relatively low at the current conference, the shooting index that does not correspond to the previous target menu has a higher rank of the first index value and the first extraction. It becomes easy to be extracted as a target menu by the unit 73. Therefore, the probability that the radiographic image 26 that has failed in the shooting of the shooting menu that does not correspond to the previous target menu will be used for browsing as the examination image 26C increases.

  Also, if the consecutive participant fails to shoot the shooting menu corresponding to the previous target menu within the previous-current period, the previous conference was not considered and the shooting skill of the continuous participant has not improved yet. It is shown that.

  In such a case, it is highly necessary to consider improvements in photography in order to prevent the consecutive participants from continuing to fail and increase the rate of increase in the loss frequency. For this reason, it is preferable that the radiation image 26 in which the consecutive participant failed in the shooting of the shooting menu corresponding to the previous target menu during the previous-current time period is browsed as the examination image 26C.

  In the present embodiment, as described above, whether or not consecutive participants have failed in the shooting of the shooting menu corresponding to the previous target menu within the previous-current time period is added to the first index value by the variable X4. For this reason, in the previous-current period, the first target value ranks higher for the previous target menu that has a greater number of consecutive participant shooting failures, and is easily extracted as the target menu by the first extraction unit 73. Therefore, there is an increased probability that the radiation image 26 in which the consecutive participant has failed in the shooting of the shooting menu corresponding to the previous target menu during the previous-current time period will be used for browsing as the examination image 26C.

  In the second extraction unit 74, a search result 95 of a failed image file in which the same shooting menu as the target menu is recorded is acquired from the failed case DB 21. The search result 95 is output to the second calculation unit 75.

  The second calculation unit 75 calculates a second index value for the failed image file of the search result 95 (step S230). The calculation result 99 of the second index value is output to the second extraction unit 74 and the screen output control unit 76.

  The second extraction unit 74 extracts a specified number of failed image files (consideration images 26C) based on the second index value calculation result 99 (step S240). Specifically, the order of the second index value is extracted in order from the failed image file, and the extraction is stopped when the number of failed image files reaches the designated number. The extraction result 104 of the failed image file extracted in this way is output to the screen output control unit 76.

  The second index value is calculated by a second calculation formula ΣYj having a variable Y1 according to whether or not a participant is associated with the failed image file of the search result 95. For this reason, the second index value becomes larger as the failed image file in which the same staff ID as that of the participant is written, and the order of the second index value becomes higher. Therefore, a failed image file in which the same staff ID as that of the participant is recorded can be extracted preferentially.

  In addition to the variable Y1, the second calculation formula ΣYj has variables Y2 to Y7 corresponding to the narrowing condition. Therefore, the second index value is larger in the case of a defective image file in which incidental information that matches the narrowing condition is written. It becomes a large value, and the ranking of the second index value also becomes high. Therefore, it is possible to preferentially extract a failed image file in which incidental information that matches the narrowing-down condition is written.

  In the second extraction unit 74, as the reference image 26R, a search for a diagnostic image file in which the same imaging menu as the target menu including the diagnostic image file in which the same patient ID as the failed image file of the extraction result 104 is described is described. The result 105 is acquired from the copy failure example DB 21 (step S250). The search result 105 is output to the screen output control unit 76.

  In the screen output control unit 76, the current staff ID information, the first index value calculation result 86, the target menu extraction result 91, the second index value calculation result 99, the failed image file extraction result 104, and the diagnosis Based on the search result 105 of the image file, the conference screen 30 is generated. The XML data of the conference screen 30 is output from the screen output control unit 76 to the client terminal 12 that is the output source of the distribution request (step S260).

  Also, the conference history information 78 is updated by the R / W control unit 77 based on the information on the current staff ID, the intermediate processing data 81 of the number of times of the current copy failure, and the extraction result 91 of the target menu (step S270).

  In the client terminal 12, the XML data of the conference screen 30 is received by the browser control unit 46 (step S110). The conference control screen 30 displayed on the web browser is reproduced based on the XML data by the browser control unit 46, and the conference screen 30 is displayed on the display 39A by the GUI control unit 45 (step S120).

  On the conference screen 30, the target menu is displayed in the target menu display area 110, and the examination image 26C is displayed in the examination image display area 112, respectively. Participants of the conference browse the conference screen 30 and examine improvement points of shooting.

  In the target menu display area 110, the target menus are arranged in descending order of the first index value. In the consideration image selection area 120, the thumbnails 121 of the examination images 26C are arranged in descending order of the second index value. When there are a plurality of target menus and review images 26C, it is possible to easily find and select the target menu and review images 26C that have a higher contribution to suppress the increase rate of the loss frequency.

  In the display column 110A of the target menu display area 110, icons 115 indicating individual participants are displayed. This icon 115 indicates that the examination image 26C taken by the participant indicated by the icon 115 exists in the examination image 26C extracted for the object menu in the display field 110B, and selects the object menu. It can be helpful when.

  The icon 115 is also displayed in the display column 120A of the examination image selection area 120. This icon 115 indicates that the examination image 26C displayed on the thumbnail 121 in the display field 120B is taken by the participant indicated by the icon 115, and is used as a reference when selecting the examination image 26C. Can do.

  In addition to or in addition to the display of the icon 115, the target menu in which the examination image 26C taken by the participant exists and the thumbnail 121 of the examination image 26C taken by the participant may be displayed separately from others. .

  On the conference screen 30, not only the examination image 26C but also the reference image 26R is displayed. Further, by selecting the information buttons 117 and 119 with the cursor 56, the supplementary information associated with the study image 26C and the supplementary information associated with the reference image 26R can also be displayed. For this reason, it is possible to compare the examination image 26C and the reference image 26R and the incidental information associated therewith. For example, it is possible to check the shooting conditions of the supplementary information associated with each of the examination image 26C and the reference image 26R and perform a lecture on how to set the shooting conditions to prevent failure.

  Note that the examination image display area 112 and the reference image display area 113 may be provided with a frame advance button and a frame return button for manually switching the display of the examination image 26C and the reference image 26R. Further, the examination image 26C may be automatically framed and displayed in the examination image display area 112 at regular intervals. In this case, it is preferable to display the examination image 26C in descending order of the second index value.

  In the first embodiment, as illustrated by the thumbnail 121 in the display column 120B of the examination image selection area 120, the examination image 26C is displayed in an arrangement according to the second index value. However, the display form of the examination image 26C is displayed. Is not limited to this. The examination image 26C may be displayed with a display size and a display position corresponding to the second index value.

  Specifically, as in the examination image selection area 130 shown in FIG. 30, the thumbnail 121 of the examination image 26C is displayed with the display size and display position corresponding to the second index value. That is, the thumbnail 121 of the examination image 26C having the higher second index value rank is displayed in a larger size, and the thumbnail 121 of the examination image 26C having the higher second index value rank is displayed near the center of the examination image selection area 130. To do. If the examination image 26C is displayed with the display size and the display position corresponding to the second index value in this way, the examination image 26C having a relatively high second index value order can be easily selected with the help of the visual effect. Note that the icon 115 may be displayed on the top of the thumbnail 121 or the like as in the consideration image selection area 120.

  In the first embodiment, a failed image to be the examination image 26C is determined by the second extraction unit 74 based on the second index value calculated by the second calculation unit 75. However, based on the second index value, It is not necessary to determine a failed image as the examination image 26C. In this case, the second calculation unit 75 is not constructed in the CPU 37B, and the second extraction unit 74 extracts, for example, a failed image file of the search result 95 in order from the latest shooting date and time. In addition, the thumbnails 121 of the examination images 26C are displayed in the examination image selection area 120 in the order from the latest shooting date and time.

[Second Embodiment]
In addition, when there is no recorded image of the staff ID at this time in the failed image file of the search result 95 searched based on the target menu by the second extraction unit 74, all of the examination images taken as a result by other than the participants as a result 26C is used for browsing.

  In the conference, the examination image 26C becomes closer to the participant and the examination is more facilitated when the radiation image 26 photographed by the participant is viewed as the examination image 26C than the radiation image 26 photographed by a person other than the participant. Therefore, it is preferable. For this reason, it is not preferable that the examination image 26C taken by all but the participants is used for browsing.

  Therefore, in the present embodiment, when there is no failed image file with the staff ID written this time in the search result 95, the second extraction unit 74 replaces the target menu and searches again for the damaged image file. Then, the replacement of the target menu and the re-search of the failed image file are continued until the failed image file in which the staff ID is recorded is searched.

  In this case, the reception unit 71 outputs information on the staff ID this time to the second extraction unit 74. As illustrated in step S <b> 500 of FIG. 31, the second extraction unit 74 receives information on the current staff ID from the reception unit 71. Similarly to the case of FIG. 18, the second extraction unit 74 searches the failure case DB 21 for a failure image file in which the same shooting menu as the target menu is recorded (step S510). Then, the staff ID recorded in the retrieved image file that has been searched is compared with the current staff ID from the reception unit 71 (step S520).

  As a result of the comparison, when there is no searched image file with the staff ID written this time (NO in step S530), the target menu used for searching for the damaged image file in step S510 is changed to another target menu. Replace (step S540). Then, the failed image file is searched in step S510 with the target menu replaced again.

  The second extraction unit 74 repeats the replacement of the target menu in step S540 and the search for the failed image file in step S510 until the failed image file in which the staff ID is recorded this time is searched (YES in step S530).

  The target menu replaced by the second extraction unit 74 is, for example, a shooting menu with the highest first index value among the shooting menus that are not extracted as the target menu by the first extraction unit 73. Referring to FIG. 17 as an example, there is no failed image file with a staff ID this time in a photographed image file in which the shooting menu “chest / standing position / front” with the first index value rank 1 is written. Replaces the second-placed shooting menu “head / sitting / front” and searches for a failed image file again. If there is no image with the staff ID recorded in the image file that was searched for in the 2nd shooting menu “head / sitting / front”, the 3rd shooting menu “abdomen / standing / back” was replaced. Then search for the failed image file again.

  In this way, since the consideration image 26C always includes a photograph taken by the participant, it is possible to avoid a situation in which the examination image 26C taken by anyone other than the participant is used for browsing. In this case, since the shooting menu having a relatively low first index value may be set as the target menu due to the replacement of the target menu, for example, the replacement target menu is displayed in the display column 110B of the target menu display area 110. Participants may be alerted by displaying a mark indicating the presence of the mark.

[Third Embodiment]
When there are a plurality of target menus extracted by the first extraction unit 73, the first index of the former is used for a target menu having a relatively high first index value ranking and a target menu having a relatively low first index value ranking. The target menu having a relatively high value rank has a higher rate of increase in the copy failure frequency and the copy loss situation is worse. Therefore, if the examined image 26C of the target menu is used for browsing, an effect of suppressing the increase in the copy loss frequency can be expected. .

  Therefore, in the present embodiment, the number of items to be extracted as the examination image 26C by the second extraction unit 74 is assigned to a target image that has a relatively high first index value rank and a poor copy status.

  In this case, the second extraction unit 74 creates intermediate processing data 135 shown in FIG. The intermediate processing data 135 includes, for example, the allocation rate of the number of failed image files to be extracted as the examination image 26C (the number of extracted examination images 26C) based on the first index values of the three target menus 1, 2, and 3. Is calculated and registered. The first index value and the ranking are the first place when the target menu 1 is “100”, the second place when the target menu 2 is “70”, and the third place when the target menu 3 is “30”.

  The allocation rate is calculated by dividing the first index value of each target menu 1 to 3 by the sum of the first index values of each target menu 1 to 3. In this case, the first index values of the target menus 1 to 3 are “100”, “70”, and “30”, and the sum of the first index values is 100 + 70 + 30 = 200. (100/200) × 100 is 50%. Similarly, the allocation rate of the target menu 2 is 35%, and the allocation rate of the target menu 3 is 15%.

  For example, when the number “100” is designated on the designation screen 50, as shown in FIG. 32, the number of extractions of the examination image 26C of the target menu 1 is 100 × 0.5, which is “50”. Similarly, the extraction number of the target menu 2 is “35”, and the extraction number of the target menu 3 is “15”.

  The second extraction unit 74 extracts a failed image file of each target menu 1 to 3 based on the intermediate processing data 135. In this way, the target menu that can be expected to have an effect of suppressing the increase in the loss frequency increases the number of extracted examination images 26C, so that a meaningful study can be performed and the contribution to the suppression of the increase in the loss frequency can be further increased. Can do.

  The number of extracted examination images 26C may not be calculated based on the first index value. For example, when the number of target menus extracted by the first extraction unit 73 is nine and the number “45” is specified on the specification screen 50, the examination image 26 </ b> C of the target menu ranked first in the first index value is extracted. The number of extractions is “9”, the extraction number of the second target menu is “8”,..., The extraction number of the eighth target menu is “2”, and the extraction number of the ninth target menu is “1”. Alternatively, the number of extracted sheets may be set by subtracting one by one as the rank decreases. In addition, when there are two target menus, the allocation rate of the first target menu is set to 70%, and the allocation rate of the second target menu is set to 30%. You may keep it.

  In the first embodiment, the number of times of image loss is exemplified as the image loss frequency. However, instead of the number of image loss times, a loss rate that is a ratio of the number of image loss times to the total number of image capturing times may be employed. In this case, the first calculation unit 72 outputs a search command not specifying the failure flag to the failure example DB 21 instead of the search command specifying the failure flag “1” as shown in FIG. Therefore, the search result 80 is a mixture of diagnostic image files and failed image files.

  First, the first calculation unit 72 pays attention to the shooting menu of the diagnostic image file and the failed image file in the search result 80, and calculates the total number of times of shooting including the number of the diagnostic image file and the failed image file for each shooting menu. Count. Next, as in the first embodiment, the number of times of shooting is counted for each shooting menu based on the number of failed image files in the search result 80, and the number of times of shooting is divided by the total number of times of shooting to obtain a shooting rate. Is calculated for each shooting menu.

  In this case, as the conference history information 78, information having copy rate data in which the previous copy rate is described for each shooting menu is stored instead of the copy number data 78A. Further, in the intermediate processing data 82, an increase / decrease amount obtained by subtracting the previous loss rate from the currently calculated loss rate, and an increase rate of the loss rate are registered. The variable X1 is a variable based on the increase rate of the copy loss rate.

  As shown in FIG. 33, a check box 140 may be provided next to each participant icon 115 in the participant display area 111 of the conference screen 30 for designating a participant to be particularly noted. When the check box 140 is selected with the cursor 56, the failed image management server 13 may be made to extract the target menu and the examination image 26C again.

  In this case, in the failed image management server 13, when the first calculation unit 72 calculates the first index value, has the participant whose check box 140 has been selected with the cursor 56 failed to shoot the target menu last time? The weighting coefficient larger than 0 is added to the variable X4 based on whether or not, and the weighting coefficient larger than 1 is multiplied. In FIG. 33, since the check box 140 of “Yasuka Hyakuyasu” of the staff ID “R0008” is selected, the variables of the shooting menus “chest / standing / front” and “chest / standing / back” shown in FIG.
