  In the medical field, medical treatment is performed using images obtained by various imaging devices and various examinations. The image data acquired by the imaging device is referred to herein as a medical image. An image obtained by subjecting image data to image processing or the like for obtaining an image suitable for diagnosis is also included in the medical image. The imaging apparatus is, for example, a computed tomography apparatus (CT), a nuclear magnetic resonance imaging apparatus (MRI), or a radiation imaging apparatus (DR: Digital Radiography) that captures a two-dimensional radiation image. The image data acquired by the CT apparatus will be described as an example. The CT apparatus acquires a one-dimensional distribution of relative X-ray absorption coefficient values called CT values as image data. Thereafter, a process called image reconstruction is performed on the image data to obtain a three-dimensional image. Further, a MIP image created by a maximum intensity projection (MIP) method and a two-dimensional image of an arbitrary tomographic plane are acquired from the three-dimensional image. These image data, a three-dimensional image, and various images acquired from the three-dimensional image are included in the medical image.

  Diagnosis using medical images is called interpretation. Interpretation is performed by observing a medical image by a doctor who specializes in image diagnosis. When a request for instructing imaging and interpretation of a medical image is issued from the diagnosis target physician, an engineer captures an appropriate medical image, and the medical image is used for interpretation. Information and advice obtained based on the taken medical image, information on the diagnosis target, and the like are transmitted from the specialist to the attending physician. Hereinafter, a doctor requesting interpretation is referred to as a requesting doctor, and a doctor specializing in image diagnosis is referred to as an interpretation doctor. Interpretation results are often described in interpretation reports and communicated to the requesting physician. The interpretation report is managed as electronic data. The interpretation report may be described in the electronic medical record and managed. In another example, the interpretation report is recorded and managed on a medium such as paper.

  Interpretation reports include information called findings that describe medical images taken by a patient, and describe the events and phenomena that have been found, and information called diagnoses that describe suspected diseases based on the findings. included. Furthermore, information describing advice to the requesting doctor such as a treatment policy may be included. Furthermore, a medical image is attached to the interpretation report. The medical image may be replaced with a thumbnail image of the medical image or information for referring to the medical image. Findings and diagnoses and their relationships are often described in natural sentences, and the method of description varies depending on the doctor who created the report. Therefore, it may take time for the requesting doctor to grasp the contents of the interpretation report.

  In recent years, a method has been proposed to create a structured interpretation report that expresses the relationship between multiple items contained in information such as medical images, findings, and diagnosis, which are diagnostic information described in the interpretation report. Has been. Each item includes contents input by the interpretation doctor. Thereby, for example, the relationship with a plurality of findings and diagnosis described in the interpretation report can be clearly expressed. By structuring the interpretation report, the workload of the interpreting doctor to be created is reduced, and the requesting doctor can easily grasp the contents.

  When describing in an interpretation report, the interpretation doctor creates relational information by associating the input items as necessary, and creates a structured interpretation report. In the interpretation report creation support system according to the embodiment of the present invention, such a structured interpretation report can be created. Furthermore, when changing the description, based on the content of the change and the related information, the items that may be further changed along with the change are specified, and the specified items are not specified Differentiate and display on the display.

The electronic medical chart editor 345 has a function of browsing and editing the electronic medical chart stored in the area 226 of the server 224 using the service 225. The inspection order management module 346 has a function of displaying the inspection order stored in the area 223 of the server 221 and adding or deleting it using the service 222.

  The interpretation report structuring service 231 supports creation, editing, and correction of a structured interpretation report. The service 231 includes a format management module 361, a structuring module 362, an extraction module 366, and a natural language processing module 370.

  The format management module 361 manages the recording format of medical document data such as structured interpretation reports and electronic medical records, and allows medical document data to be stored and communicated. Here, the recording format of the medical document data is a data format such as an electronic medical record or an interpretation report, or a communication standard. The standard may be an independently defined standard, a public standard, or a combination or hybrid thereof. The module 361 converts the interpretation report into a predetermined medical document data format and stores it in the area 234 for management. The module 361 exchanges medical document data with the application 214 and other services (not shown).

  The structured module 362 provides functions for creating, editing, and modifying structured interpretation reports. The structuring module 362 includes an editing module 363, a change range specifying module 364, and a change classification module 365. The editing module 363 has a function for inputting and editing a structured interpretation report, and edits the interpretation report in accordance with the input from the input module 343 of the PC client 213. The operation input from the input device 104 is interpreted by the input module 343, and the edited content of the interpretation report is obtained. The edited content is transmitted to the structuring module 362 of the server 230 and displayed on the display device 109 by the display module 342. As a result, the image interpretation doctor 202 can check the editing contents as appropriate, so that the function of the editing module 363 can be used. In this way, the interpretation doctor 202 can execute input and editing of a structured interpretation report.

The change classification module 365 controls the extraction module 366 and the analysis module 371.

  The natural language processing module 370 analyzes the text in the medical document. The natural language processing module 370 has an analysis module 371. The analysis module 371 performs so-called morphological analysis and syntax analysis. Morphological analysis is to divide a character string in a sentence into words and classify them into parts of speech, and to remove the use, refraction, etc., and obtain the original notation such as a prototype or basic form. By morphological analysis, the sentence is analyzed to form a word string. A general dictionary 372, which is a dictionary of words, is used for morphological analysis. In the syntax analysis, the word string that is the result of the morphological analysis is used to analyze the relationship and structure such as the syntax and dependency using information such as grammar. By syntactic analysis, the word string is in the form of a word tree structure (syntax tree) based on syntax, a dependency network structure (dependency relationship), or the like. The natural language processing module 370 outputs the analysis result to the extraction module 366.

  Based on the analysis result of the natural language processing module 370, the extraction module 366 extracts language expressions such as medical terms included in the text in the medical document and words and phrases attached to the medical terms. The extraction module 366 outputs the extracted medical term and the processing result, which is information on the accompanying expression, to the structuring module 362. The extraction module 366 uses a medical term dictionary 367, medical term co-occurrence pattern statistical information 368, and a perceptual expression dictionary 369. The medical term dictionary 367 has information such as a written character string and an expression pattern for medical terms such as a name representing an abnormality on a medical image, a lesion name, a disease name, and an accompanying expression. The incidental expression included in the medical term dictionary 367 is an expression indicating a degree, a size, a shape, and the like for expressing contents and a state of an abnormality or a lesion. The extraction module 366 can extract medical terms by using the medical term dictionary 367 and extract incidental expressions. The medical term co-occurrence pattern statistical information 368 includes information on what words and expressions the medical terms co-occur in the text. The extraction module 366 uses the medical term co-occurrence pattern statistical information 368 to estimate an attribute of an unknown term when an unknown medical term or an accompanying expression appears. The perceptual expression dictionary 369 includes perceptual expression information such as an expression indicating existence or confirmation, an expression indicating thought or judgment, an expression indicating a request or a request, or an expression indicating negation. The expression indicating presence or confirmation is, for example, expressions such as “having” or “visible”. Examples of expressions indicating thoughts and judgments are expressions such as “acknowledge” and “think”. The expression indicating a request or request is, for example, an expression such as “please please” or “wish”. The extraction module 366 extracts a perceptual expression using the perceptual expression dictionary 369.

  The change classification module 365 analyzes the text in the medical document by controlling the extraction module 366 and the natural language processing module 370, and outputs the analysis result to the structuring module 362 to support correction. Details of the correction support function will be described later with reference to FIG.

  The interpretation report work management service 232 has a function of performing business support and management for creating an interpretation report. For example, the service 232 assigns the interpretation report creation work to the interpretation doctor, notifies the assigned work to the interpretation doctor, manages the progress of the work, and manages the change history of the report. As a result, when there are multiple interpreting doctors or when it is necessary to create a large number of interpretation reports, priority is given to work sharing in units of interpretation reports and interpretation report creation work that requires urgency. Can do. Interpretation work information 351 is recorded and stored information regarding the creation work state for each interpretation report. The service 232 manages the status and history of the interpretation report being created, and accumulates information on the work and display contents by the interpretation report editor 341. When the service 232 further interrupts and restarts the interpretation report creation work, the service 232 outputs the state of the work before the interruption and the change history to the interpretation report editor 341 and restores based on the accumulated information. The interpretation state / history information 352 is obtained by recording and accumulating information on the work state and change history for each interpretation doctor. In this way, the service 232 supports the interpretation report creation work and manages the change history.

  The interpretation report management service 233 has a function of storing a created interpretation report or an interpretation report being created in the area 234, and creating, registering, storing, managing, referring to, and sharing the stored interpretation report. The interpretation report is input by the interpretation doctor 202 using the interpretation report editor 341, and the contents are managed by the interpretation report management service 233 and stored in the area 234.

  With such a configuration, the interpretation doctor 202 can create a structured interpretation report and use a support function for a task of correcting the interpretation report. The interpretation doctor 202 uses the electronic medical record editor 345 to view the patient's electronic medical record information and obtain information by the function of the electronic medical record management service 225. The interpretation doctor 202 subsequently uses the medical image viewer 344 to browse the medical image of the patient from the medical image management service 228 and make a diagnosis based on the image. The interpretation doctor 202 uses the interpretation report editor 341 when describing the result of image diagnosis as an interpretation report. The functions of the interpretation report structuring service 231 and the interpretation report management service 233 can be used by the interpretation report editor 341. With the functions of these services, findings and diagnosis information are structured and described to create an interpretation report, which is stored and recorded in area 234. Further, if necessary, the interpretation report editor 341 can be used to refer to the patient's past interpretation reports by the function of the interpretation report management service 233. When referring to a past interpretation report, the medical image viewer 344 can be used to refer to a medical image when a past interpretation report is written by the function of the medical image management service 228. Based on the findings described in past interpretation reports, when the follow-up observations are described in the currently created interpretation report, the relationship between the findings in the past interpretation report and the findings in the current interpretation report is also included. Recorded as interpretation report information. The record at the time of the interpretation work is recorded by the function of the interpretation report work management service 232. Thereby, when the work is interrupted and resumed, the interpretation report editor 341 can reproduce the situation of the work before the interruption and resume the work promptly.

  The interpretation doctor 202 can divide and describe each finding / diagnosis item and input the relationship between the items, thereby creating an interpretation report in which the relationship between each finding / diagnosis is easy to understand. In addition, the description contents of the findings and diagnosis items can be related to other interpretation reports.

  4 and 5 show examples of screens used when creating a structured interpretation report.

  FIG. 4 is an example of a screen that the medical image viewer 344 displays on the display device 109. In the window 401, there is a menu bar 402 for calling up processes and functions, and a medical image display area 403. Menu elements 404 such as “image selection” and “display” are displayed in the menu bar 402. The image interpretation doctor 202 selects a menu element indicating the processing / function to be performed from the menu bar 402 and inputs an operation. Thereby, for example, a medical image can be displayed in the display area 403 in a desired size, position, and display mode. An area 405 is the contents of the medical image displayed in the display area 403. Here, in the area 405, an image representing a cross section of the patient, which is taken by the CT apparatus, is displayed.

  FIG. 5 is an example of a screen displayed on the display device 109 by the interpretation report editor 341. Each area in the window 501 will be described. The menu bar 502 receives an operation input for calling a process or a function. Patient information is displayed in the patient information area 503. In the request information area 504, the request contents of the image diagnosis from the requesting doctor are displayed. The report display area 505 displays the contents of the structured interpretation report. Menu elements 506 such as “report selection”, “input”, and “display” are displayed in the menu bar 502. The image interpretation doctor 202 selects a menu element indicating the processing / function to be performed and inputs an operation. For example, an input menu for an interpretation report is selected, an input screen is displayed in the area 505, and findings and diagnosis are described in a structured state. In addition, the relationship between medical images corresponding to a certain finding and the relationship between items such as findings between a plurality of interpretation reports can be described. Images 507, 511, and 513 are medical images attached to the interpretation report. Here, the images 507, 511, and 513 are thumbnail images of medical images. The interpretation report editor 341 can attach the medical image displayed on the medical image viewer 344 to the interpretation report. At that time, all or a part of the medical image is pasted as a thumbnail image on the interpretation report. When a thumbnail of a medical image is selected, the medical image viewer 344 displays the medical image as it was attached to the interpretation report. The thumbnail of the medical image is associated with information about the corresponding medical image and work information such as the position and size displayed on the medical image viewer 344 when attached to the interpretation report. Stored in By using this to select a thumbnail of a medical image, the display when attached to the medical image viewer 344 can be reproduced. Items 508, 512, 513, and 514 are items describing the contents of the findings. An item 509 is an item describing the contents of diagnosis. An item 510 is a part for describing a future treatment policy such as a treatment or a plan. Relation lines are drawn between the items 507 and 508, between the items 511 and 512, and between the items 513 and 514. The relationship line associates each finding with a thumbnail image. The relationship line indicates the relationship between the whole or a part of the medical image indicated by the thumbnail and the findings obtained by observing the medical image. Some findings are obtained from information other than medical images, and some are not obtained from specific medical images. In these cases, the relationship line with the thumbnail is not displayed, indicating that there is no corresponding relationship with the thumbnail. Relation lines are also drawn between the items 508, 512 and 509. This shows the relationship between the findings items and the diagnosis items based on the findings. That is, in this case, the findings described in the items 508 and 512 indicate that the disease name described in the item 509 is suspected. Further, a relationship line is drawn between the item 509 and the item 510. This is associated with recommending the treatment policy described in the item 510 from the disease name described in the item 509 and its medical condition. The treatment policy is, for example, an indication that an examination is desired. That is, the relationship line is relationship information indicating the relationship between a plurality of items included in each of a plurality of pieces of information such as findings and diagnosis included in the interpretation report.

  The interpretation doctor 202 attaches a thumbnail image corresponding to the medical image by the interpretation report editor 341, creates each item of findings, diagnosis, treatment and plan, and describes the contents of the findings and diagnosis in each item. Can do. In addition, the relationship is clarified by adding a relationship line between the thumbnail, findings, diagnosis, and treatment / plan items. The relationship information indicated by the relationship line is a causal relationship indicating a cause and a result, for example. For each thumbnail of the observed medical image, each content obtained by observation by the interpreting doctor 202 having medical knowledge is an item of observation, and the correspondence between the medical image and the item of observation is expressed by a relation line. Is done. In addition, the individual contents pointed out by the interpretation doctor 202 who has medical knowledge for the findings after judging the disease name, medical condition, etc. are the diagnosis items, and the causal relationship between the observation items and the diagnosis items is expressed by a relation line. Is done. Similarly, for diagnosis, the contents of treatments and examinations, which are treatment policies recommended by the interpreting doctor 202 having medical knowledge, are items of treatments and plans, and their correspondences and causal relationships are expressed by relationship lines. In this way, a structured interpretation report is created. The display of the relationship line may be distinguished according to the logical relationship intended by the creator of the interpretation report. For example, a simple correspondence relationship is represented by a solid line, a causal relationship is represented by a solid line thicker than a solid line indicating a simple correspondence relationship, and an opposing relationship is represented by a broken line. In another example, each logical relationship is expressed in different colors. The user can arbitrarily set the display of the relationship line corresponding to each logical relationship. By associating the relationship between items with the display of the relationship line indicating the relationship, the user can easily grasp the relationship between the items.

  The description of the structured interpretation report created as described above may be changed. For example, for the contents once created, it is necessary to review the findings and diagnosis contents to confirm whether there are any mistakes, or to recommend the contents described in the interpretation report. In addition, an interpretation report created by a certain interpreting doctor may be confirmed by another interpreting doctor, and suggestions for the description may be input. In addition, the requesting doctor may read the interpretation report and may exchange questions with the interpretation doctor such as a question, an answer to the question, or a request, and the description content may be corrected. In these cases, simple typographical errors or expressions that are difficult to understand may be corrected. In addition, in order to make the findings and diagnosis more clear, information may be added, or information that may become a request or an answer generated in the exchange with the requesting doctor may be added. In addition, the description and diagnosis may be reviewed to change the description, and as a certain item is changed, the description of other items may be changed.

  If there is an error correction without changing the contents of the image diagnosis or additional information, there is a tendency to change only that item. When the contents of the image diagnosis are changed, if an item is changed, an item related to the item may be changed. In a conventional interpretation report in which all findings and diagnosis contents and their relations are all described in natural language, the interpreting doctor should work with care so that no change leaks related to a certain change occur. I was going. Therefore, it was necessary to check whether there was any change while reading all the description.

  In the interpretation report creation support apparatus according to the embodiment of the present invention, the relationship information indicating the relationship between each item and the information indicating the content of the change, which are attached to the structured interpretation report, are used. And the range which may be changed newly with the said change is estimated, and the item contained in the said range is specified. The identified item that is likely to be changed and the item that is unlikely to be changed are distinguished from each other and displayed on the display unit. An item that is likely to be changed is identified and displayed separately from other items, so that an interpreting doctor who creates an interpretation report can easily find an item to be confirmed. By this. When the interpretation report is changed, it is possible to support the change of other items not to be overlooked. Details will be described below.

  The change classification module 365 estimates the content of the change from the text described in the findings and diagnosis items. Hereinafter, what type of change has been made is referred to as a change type. Further, the change range specifying module 364 specifies the change influence range based on the item in which the change has occurred and the change type. In the present embodiment, the change range specifying module 364 specifies the change influence range using the estimation rule.

  FIG. 6 is a flowchart illustrating the flow of processing by the interpretation report creation support apparatus according to the embodiment of the invention. Here, a case is described as an example in which, after a structured interpretation report is created, a change operation is input for a certain item and the change work starts. It should be noted that the input history since the start of the interpretation report creation is accumulated as the interpretation report status / history information in the area 352 of the server 230. By using this, the functions of the processing shown in FIG. Provided from the start of report creation. Hereinafter, each step of the processing shown in FIG. 6 will be described.

  In S601, the information of the interpretation report to be changed, the identification information of the user who makes the change, and the time when the change was started are acquired. The information of the interpretation report to be changed is included in each of the plurality of pieces of information for diagnosis such as medical images, findings, and diagnosis included in the interpretation report in which the input for changing the description has been made. This is relationship information indicating the relationship between a plurality of items. The information of the interpretation report to be changed can be acquired from the storage means when the change is made during the creation of the interpretation report. The storage means is, for example, the area 351 of the server 230 for storing the work of the RAM 103 of the PC client 213, the external storage device 106, and the interpretation report editor 341 and the interpretation work information that is information of the display contents. When an interpretation report created in the past is acquired and changed, it can be obtained from a storage unit such as the area 234 of the server 230 that stores the created interpretation report. An interpretation report stored in a portable recording medium such as a CD-ROM may be obtained by converting it into a medical document format by the function of the format management module 361. The user identification information is, for example, the name of an interpreting doctor who changes an interpretation report or an ID for identifying the interpreting doctor. When the user activates an interpretation report editor 341 which is one of the applications of the PC client 213, the display module 342 may display a screen for inputting user identification information on the display device 109. As a result, the input user identification information is stored in the RAM 103 or the external storage device 106 of the PC client 213, and the input content is transmitted to the server 230 by the input module 343 and managed by the interpretation report work management service 232. Good.

  In S602, the change content is acquired. The change contents are acquired by the input module 343, transmitted to the server 230, and managed by the service 232.

  In S603, the change contents are separated for each changed item. That is, the item in the interpretation report is identified as the item that has been changed. For example, it is assumed that the changed item is one item among a plurality of items included in the finding information.

  In S604, the contents of change are recorded for each item that has been changed according to the result of separation in S603. According to the example given in S603, the change content is recorded as a change history of one specified item among a plurality of items included in the finding information. With the processing in S603 and S604, the change contents can be managed for each item that has been changed. The content of the change is recorded in the area 352 of the server 230 as the interpretation report status / history information. The data may be stored in accordance with the RAM 103 of the PC client 213 or the external storage device 106. This recorded change content is retained at least until the end of the change.

  In S605, it is determined whether or not the change is confirmed. For example, the display module 342 of the interpretation report editor 341 arranges a confirmation button in the vicinity of the item that has been changed so as to be displayed on the display device 109 of the PC client 213. When an operation input to the confirmation button is performed, it is determined that the change has been confirmed. If the change is confirmed, the process proceeds to S613, and if not, the process proceeds to S606.

  In S606, the text described in the finding or diagnosis item that has been changed is analyzed by natural language processing. The natural language processing module 370 acquires the contents described in the changed item and causes the analysis module 371 to analyze it. An example of natural language processing will be described with reference to FIG.

  The text in FIG. 7A is an example of the text of the interpretation report. FIG. 7B illustrates the result of processing the text in FIG. 7A in S606. The column “notation” in FIG. 7B illustrates the result of separating the example sentence in FIG. 7A into words by morphological analysis. Further, the “part of speech” column exemplifies information on the part of speech assigned to each notation separated by the morphological analysis. The “syntax structure” column exemplifies the result of parsing each notation separated by morphological analysis. The syntax structure is, for example, a phrase structure. Therefore, the “syntax structure” column has a two-level syntactic structure of a part constituting a basic unit of a phrase such as a noun phrase and a verb phrase and a part constituting a relationship with another phrase such as a postpositional phrase. It is shown. Furthermore, the main verb phrases that are main in terms of the modification-modification relationship and the syntactic structure are extracted by syntactic analysis. In the case of Japanese, a particle appears immediately after a noun (phrase) and has a syntactic relationship with other noun phrases and verb phrases. A noun phrase accompanied by a postposition is expressed as a postpositional phrase. Postpositional phrases are sometimes called phrases. The analysis module 371 uses the general dictionary 372 and the syntax rules 373 when performing morphological analysis and syntax analysis. The general dictionary 372 has word information. The syntax rule 373 includes information on a combination of words forming a phrase structure, a relationship between phrase structures, and a structure. The processing methods and processing result forms of morphological analysis and syntax analysis are not limited to those illustrated in FIG. 7, and it is only necessary to obtain processing and processing results corresponding thereto.

  In step S607, medical terms are extracted based on the analysis result obtained by the natural language processing obtained in step S606. The extraction module 366 uses the medical term dictionary 367, the medical term co-occurrence pattern statistical information 368, and the perceptual expression dictionary 369 to extract medical terms, supplementary expressions of medical terms, and perceptual expressions. Divide into categories. As a technique for extracting these terms, incidental expressions, and perceptual expressions and dividing them into categories, for example, it is possible to extract by referring to the medical term dictionary 367 of the extraction module 366 for each word unit. In another example, using the medical term co-occurrence pattern statistical information 368 or the like, even if the expression is not registered in the dictionary, the composition of the expression itself or other words that co-occur with the expression are used. And can be estimated.

  FIG. 8 is a diagram exemplifying the extraction result in S607. Here, a result obtained by performing extraction processing based on the result shown in FIG. 7B obtained by performing morphological analysis and syntax analysis on the example sentence in FIG. 7A is shown as an example. FIG. 8 shows the results divided into “term expression”, “accompanying expression”, and “perceptual expression”. Hereinafter, these are collectively referred to as an extracted expression. The term expression is an expression that is extracted as a medical term such as a name or disease name that expresses a site, a lesion, or an abnormality. The incidental expression is an expression attached to a medical term such as an expression indicating “shape” or “size” or an expression indicating “concrete”. The incidental expression indicates information that is an attribute of the term expression to be added. Perceptual expression means “perception” and “recognition” such as recognition of “acknowledge”, “visible”, “suspect”, direct expression of possibility, and expression of existence such as “present”, “accompanied”. It is an expression to show. The perceptual expression indicates the degree or state when the interpreting doctor recognizes or perceives the added term expression or incidental expression. The additional structure is determined from the result of parsing as shown in FIG.

  In step S608, the extraction result obtained in step S607 is compared with the extraction result processed last time, and change detail information is acquired based on the difference from the previous extraction result. Here, the extraction result processed last time is, for example, an extraction obtained by the processing shown in FIG. 6 when the change has been made before and the processing shown in FIG. It is a result. Since the input history since the start of the interpretation report creation is accumulated as the interpretation report status / history information in the area 352 of the server 230, the previously extracted extraction result can be obtained from the history information. it can. Therefore, the process of S608 is not limited to the case where a change has been made before for the item that has been changed. The change detailed information is obtained by, for example, classifying and comparing each of the “terminology expression”, “accompanying expression”, and “perceptual expression” of the extracted expression shown in FIG. It is done. By comparison, information such as the presence / absence in the previous extraction result of each expression of “term expression”, “accompanying expression”, and “perceptual expression”, and increase / decrease of the number are obtained. Hereinafter, this is referred to as change detailed information.

  In S609, a change type is estimated by the change classification module 365 based on the change detailed information obtained in S608.

  In S610, the change influence range is specified by the change range specifying module 364 from the change type estimated in S609 and the change target information.

  FIG. 9 shows an example of a rule for estimating the change type from the detailed change information in S609 and S610. “Rule ID” shown in FIG. 9 is a management number of each rule. Each rule shown in FIG. 9 determines the change type and the influence range estimated based on the change detailed information. The change detailed information shown in FIG. 9 shows, as an example, the information obtained by the processing of S608 for the extracted expression for each category of the extracted expression while considering the structure of the extracted terms shown in FIG. Based on this detailed change information, the corresponding rule is specified.

  When there is no change in the extracted term, R901 is applicable, the change type is estimated as “erroneous correction / expression change”, and the change influence range is limited to only the item that has been changed. That is, when the content of the change is a change that corrects an error, only the changed item is specified by the change range specifying module 364. Further, the rule of R901 is also applied immediately after the start of a change for a certain item and no change content is input.

  For example, when the description of “right lung” is changed to “left lung” in a certain item included in the finding information, the change detailed information is acquired as “change of expression of part name”, and the rule of R902 is applied. Is done. According to the rule of R902, the change type is presumed to be “change of object of finding”, and the change influence range is from the finding item, the image referred to in the finding, and the diagnosis item derived from the finding. Furthermore, if there are related items described with reference to the findings and diagnoses related to the findings, they are also included in the scope of change. In addition, when changing about a related image with a certain change, the case where the marker for showing the characteristic area on an image is added or moved is mentioned, for example. When the region is changed, there is a possibility that a change in the marker position on the image or a change in diagnosis guided in combination with other information may occur. That is, when the content of the change is a change in the description about the part, the changed item, the item associated with the changed item, information on the image to be diagnosed, The items included in the information on the findings on the image, the information on the diagnosis on the diagnosis target, and the information on the treatment policy derived from the diagnosis are specified. In addition, when changing about a related image with a certain change, the case where the marker for showing the characteristic area on an image is added or moved is mentioned, for example.

  For example, when the description of “nodule” is changed to “mass” in a certain item included in the findings information, the change detailed information is acquired as “change of expression of lesion / abnormal name”, and the rule of R903 is applied. Is done. The change type is presumed to be “change in the content of the findings”, and the change influence range includes the items of the findings, the images referred to in the findings, and the diagnosis items derived from the findings. Furthermore, if there are related items described with reference to the findings and diagnoses related to the findings, they are also included in the scope of change. When the name of a lesion is changed, there is a possibility that a change in the position or range of a marker indicating the lesion on the image, or a change in diagnosis derived in combination with other information may occur. That is, when the content of the change is a change in the description about the name of the lesion, the changed item, the item related to the changed item, and information on the image to be diagnosed The items included in the information on the findings about the image, the information on the diagnosis on the diagnosis target, and the information on the treatment policy derived from the diagnosis are specified.

  For example, in a certain item included in the findings information, if the description “accept nodules” is changed to “not accept nodules”, the detailed change information will be “the perceptual expression added to the lesion / abnormal name. Change "and the rules of R904 are applied. The change type is presumed to be “change in the content of the findings”, and the change influence range is from the findings items to the diagnosis items derived from the findings. Furthermore, if there are related items described with reference to the findings and diagnoses related to the findings, they are also included in the scope of change. Changed findings information can lead to changes in diagnosis derived from findings. In addition, when the description of “no nodules” was changed to the description of “nodules allowed”, the findings were changed because a new feature on the image was overlooked by the interpreting physician. Can think. Therefore, in order to prevent the user from overlooking the attachment of the image referred to in the observation or the addition of the marker indicating the feature region on the image corresponding to the added lesion, the image related to the change influence range is included. May be. When the image is not associated with the finding, the change influence range for displaying the thumbnail image is displayed in the same manner as the other change influence ranges. In other words, when the content of the change is a change in expression indicating recognition of a lesion, the changed item and the item related to the changed item, the findings on the image to be diagnosed At least items included in each of the information, the diagnosis information for the diagnosis target, and the information about the treatment policy derived from the diagnosis.

  For example, in the case where the description “Reticulated shadow” is added to an item that does not include an expression that indicates a lesion or abnormality, in particular, the change detailed information is “ Add ”is acquired, and the rules of R905 are applied. The change type is presumed to be “addition of findings content”, and the change influence range is an item of the findings that have been changed. Any relevant items described with reference to these findings are also included in the scope of change impact. If a diagnosis has already been made, an expression indicating a lesion or abnormality may not be described in the findings item. In such a case, even if the doctor adds an expression indicating a lesion or abnormality to the finding item, the diagnosis derived from the finding may not change. Therefore, in the example shown in FIG. 9, the change influence range is the finding item that has been changed and the related item that is described with reference to the finding. That is, when the content of the change is a change in which a description about the lesion name is added to an item that has no description about the name of the lesion, at least the changed item is specified.

  For example, when the description “spicula” is added to a certain item included in the finding information, the change detailed information is acquired as “addition of expression of lesion / abnormal name”, and the rule of R906 is applied. The change type is presumed to be “change in the content of the findings”, and the change influence range is from the findings items to the diagnosis items derived from the findings. Furthermore, if there are relevant items described with reference to the findings, they are also included in the scope of change impact. When a representation of a lesion is added, a diagnosis change guided by the added lesion information may occur. Further, it can be considered that a lesion name is added because a feature that has been overlooked is newly found on the image, and the image referred to in the finding may be included in the change influence range. Thereby, it is possible to assist the user not to overlook the addition of the marker indicating the feature region on the image corresponding to the added lesion. That is, if the content of the change is a change that adds a description about the name of the lesion, the changed item and the item related to the changed item, the image to be diagnosed At least items included in each of the information on the findings, the information on the diagnosis on the diagnosis target, and the information on the treatment policy derived from the diagnosis are specified. Even when the above-described R905 rule is applied, the R906 rule may be applied.

  For example, when the description of “low absorption range” is changed to “high absorption range” in a certain item included in the findings information, the change detailed information is acquired as “change of expression of image feature name” and the rule of R907 is Applied. The change type is presumed to be “change in the content of the findings”, and the change influence range is from the findings items to the diagnosis items derived from the findings. Furthermore, if there are relevant items described with reference to the findings, they are also included in the scope of change impact. The change in the expression of the image feature name may be a change accompanied by a change in the position of the feature region on the image, and the image referred to in the finding may be included in the change influence range. That is, if the content of the change is a name change indicating the characteristics of the image to be diagnosed, the changed item and the item associated with the changed item, At least items included in the information on the findings on the image, the information on the diagnosis on the diagnosis target, and the information on the treatment policy derived from the diagnosis are specified.

  For example, when the description of “accepting low absorption range” is changed to “not allowing low absorption range” in a certain item included in the findings information, the change detailed information is “change of perceptual expression added to image feature name” ”And the rules of R908 are applied. The change type is presumed to be “change in the content of the findings”, and the change influence range includes the items of the findings, the images referred to in the findings, and the diagnosis items derived from the findings. Since whether or not a region showing a certain feature is recognized on the image has been changed, there is a possibility that the image and the diagnosis derived from the changed findings may change. Furthermore, if there are related items described with reference to the findings and diagnoses related to the findings, they are also included in the scope of change. That is, when the content of the change is a change in the expression added to the name indicating the characteristics of the image to be diagnosed, the changed item is an item related to the changed item. Thus, items included in the information on the image to be diagnosed, the information on the findings on the image, the information on the diagnosis on the diagnosis target, and the information on the treatment policy derived from the diagnosis are specified.

  For example, if the description “low absorption range” in a certain item included in the findings information is added to an item that does not include an expression indicating the feature of the image, the change detailed information is “ Add ”is acquired, and the rules of R909 are applied. The change type is presumed to be “addition of findings”, and the item of the finding becomes the change detail range. Any relevant items described with reference to these findings are also included in the scope of change impact. If a diagnosis has already been made, an expression indicating the characteristics of the image may not be described in the finding item. In such a case, the diagnosis derived from the findings may not change even if the doctor adds an expression indicating the characteristics of the image to the findings item. Therefore, in the example shown in FIG. 9, the change influence range is the finding item that has been changed and the related item that is described with reference to the finding. That is, if the content of the change is a change that adds a name indicating the characteristics of the image to be diagnosed to an item for which there is no description about the name indicating the characteristics of the image to be diagnosed, at least the change is made. Items are identified.

  For example, when the description “low absorption range” is added to a certain item included in the findings information, the change detailed information is acquired as “addition of expression of image feature name”, and the rule of R910 is applied. The change type is presumed to be “change in the content of the findings”, and the change influence range is from the findings items to the diagnosis items derived from the findings. Furthermore, if there are relevant items described with reference to the findings, they are also included in the scope of change impact. When an expression indicating the feature of the image is added, there is a possibility that a diagnosis change guided by the added finding information may occur. Moreover, it can be considered that an expression indicating the feature is added because a feature that has been overlooked is newly found on the image, and the image referred to in the finding may be included in the change influence range. Thereby, it is possible to assist the user not to overlook the addition of the marker indicating the feature region on the image corresponding to the added lesion. That is, when the content of the change is a change that adds a name indicating the feature of the image to be diagnosed, the changed item and the item associated with the changed item, At least items included in the information on the findings on the image of the object, the information on the diagnosis on the diagnosis object, and the information on the treatment policy derived from the diagnosis are specified. Even in the case where the above-described R909 rule is applied, the R910 rule may be applied.

  For example, when the description “nodule is recognized” is changed to “a 1 cm nodule is recognized” in a certain item included in the findings information, the change detailed information is “an image feature name or an incidental representation of a lesion / abnormal name”. Add ”is acquired, and the rules of R911 are applied. The change type is presumed to be “addition of findings”, and the item of the observation becomes the change influence range. Furthermore, if there are relevant items described with reference to the findings, they are also included in the scope of change impact. If a diagnosis has already been made, the incidental expression of the lesion may not be described in the findings item. In such a case, even if a doctor adds an incidental expression of a lesion to the finding item, the diagnosis derived from the finding may not change. Therefore, in the example shown in FIG. 9, the change influence range is the finding item that has been changed and the related item that is described with reference to the finding. The same applies to the case where an accompanying expression of a name indicating the feature of the image is added. That is, when the content of the change is a change that adds an expression indicating the degree or shape of the feature of the diagnosis target image, at least the changed item is specified. When the content of the change is a change that adds an expression indicating the degree or shape of the lesion, at least the changed item is specified.

  For example, in a certain item included in the findings information, if the description “1 cm nodule is recognized” is changed to “an irregular 1 cm nodule is recognized”, the change detailed information is “image feature name or lesion / “Addition of an anomaly name supplementary expression” is acquired, and the rule of R912 is applied. The change type is presumed to be “change in the content of the findings”, and the change influence range is from the findings items to the diagnosis items derived from the findings. Furthermore, if there are relevant items described with reference to the findings, they are also included in the scope of change impact. If some additional expression is added to a lesion name that already has an accompanying expression, the diagnosis derived from the changed findings may change. For example, the extent and shape of the lesion may be important information for confirming the diagnosis. That is, when the content of the change is a change in which an expression indicating the size, degree, or shape is further added to the name indicating the feature of the image to be diagnosed accompanied by an expression indicating the size, degree, or shape Is the item that has been changed, the item that is related to the item that has been changed, information about the findings of the image to be diagnosed, information about the diagnosis of the image to be diagnosed, and the treatment policy derived from the diagnosis Items included in each of the information about are identified. In addition, when the content of the change is a change in which an expression indicating the size, degree, or shape is added to the name of a lesion accompanied by an expression indicating the size, degree, or shape, the change is made. Items, items related to the changed items, information on findings on the image to be diagnosed, information on the diagnosis on the object to be diagnosed, and information on the treatment policy derived from the diagnosis The included items are identified.

  For example, if the description of “granuloma” is changed to “primary lung cancer” in a certain item included in the diagnosis information, the change detailed information is acquired as “addition / change of expression of disease name” and the rules of R913 are applied. The The change type is presumed to be “change of diagnosis contents”, and the change influence range is from the diagnosis item to the finding item leading to the diagnosis. When disease names are added or changed, there are changes in findings that lead to such changes, and the findings may change. Furthermore, if there are relevant items described with reference to the findings, they are also included in the scope of change impact. That is, when the content of the change is a change in the name of the disease to be diagnosed, the changed item and the item related to the changed item, the information on the findings on the image to be diagnosed Then, items included in each of the diagnosis information for the diagnosis target and the information on the treatment policy derived from the diagnosis are specified. In addition, in the case of a change to add a disease name to be diagnosed, the changed item, the item related to the changed item, information on findings on the diagnosis target image, and diagnosis Items included in each of information on diagnosis for a subject and information on a treatment policy derived from the diagnosis are specified.

  For example, when the description “lung cancer is not suspected” is changed to “suspect lung cancer” in a certain item included in the diagnosis information, the change detailed information is acquired as “correction of perceptual expression added to disease name”, and R914 The following rules apply. The change type is presumed to be “change of diagnosis contents”, and the change influence range includes the diagnosis item, the finding item leading to the diagnosis, and the diagnosis target image. If there is a change in the content of the diagnosis, there may be a change in the findings leading to such a change, and there will also be a change to indicate the feature region of the image that will lead to such a change in the findings there is a possibility. Furthermore, if there are relevant items described with reference to the findings, they are also included in the scope of change impact. That is, when the content of the change is a change in the expression added to the name of the disease to be diagnosed, the changed item and the item associated with the changed item, The items included in the information on the findings on the image, the information on the diagnosis on the diagnosis target, and the information on the treatment policy derived from the diagnosis are specified.

  The rule as illustrated in FIG. 9 can be arbitrarily set by the user. Items included in the change influence range estimated by this rule are searched. For example, when the part labeled “Right Lung” is changed to “Left Lung”, R902 is applied, and “Image-Findings-Diagnosis-(Related)” becomes the change influence range. The change influence range includes the image and diagnosis items that are related to the finding item that is currently being changed, and the items associated with those items. The change range identification module 364 searches for an image related to the finding item that has been changed, and if so, includes it in the change influence range. Similarly, the diagnosis item associated with the changed finding item is similarly processed. Further, an item related to an item included in the change influence range is searched, and if included, it is included in the change influence range. In this way, items included in the change influence range are specified. Note that the change influence range is specified based on the content of the change and the relationship information related to the item that has been changed, and the change type does not necessarily have to be estimated in the rules illustrated in FIG. By presuming the change type in advance, a part of the process to be performed for specifying the change influence range and the process related to the display of the specified change influence range is determined. it can.

  In S611, the change influence range specified in S610 is compared with the previous change influence range, and it is determined whether or not to update the display of the change influence range. Here, the previous change influence range is, for example, the change influence range obtained by the process shown in FIG. 6 when the change has been previously made and the process shown in FIG. 6 is performed. is there. Since the input history since the start of the interpretation report generation is stored as the interpretation report status / history information in the area 352 of the server 230, the change influence range obtained last time is obtained from the history information. Can do. If the comparison results are the same, the process proceeds to S602, and if not, the process proceeds to S612.

  In S612, the change influence range obtained last time is updated to the change influence range specified in S610. The editing module 363 outputs information about the changed influence range updated to the PC client 213. The PC client 213 causes the display module 342 of the interpretation report editor 341 to display the updated change influence range on the display device 109 of the PC client 213 based on the information about the updated change influence range. Here, the display of the change influence range is to distinguish and display items specified as the change influence range by the change range specifying module 364 and items not specified. That is, the editing module 363 functions as a display control unit that displays the item specified by the change range specifying module 364, which is the specifying unit, on the display device, which is a display unit, in distinction from the item not specified by the specifying unit. For example, the items included in the change influence range can be distinguished by surrounding them with a frame, or the identified items and the unidentified items can be displayed in different colors. That is, when at least one of the plurality of items included in the interpretation report is changed by the processing up to S612, based on the content of the change and the relationship information about the changed item. Thus, at least one of the plurality of items included in the interpretation report is specified, and the specified item is displayed separately from the unspecified item.

  When the process of S612 is completed, the process proceeds to S602 and the above-described process is performed. When the change is confirmed in S605, the process proceeds to S613.

  In S613, the recorded change contents are structured by associating the change type, the user identification information, the start time and the end time of the change for each changed item, and processing to obtain a change history is performed.

  In S <b> 614, the interpretation report work management service 332 updates and records the history information created in S <b> 613 as the revision history confirmed in the interpretation report status / history information 352.

  Through the processing as described above, a change in one item and a change influence range associated with the change are displayed. Note that the process for specifying and displaying the change influence range illustrated in FIG. 6 can be performed in parallel for the change of a plurality of items. In this case, when the processing related to the change of other items is started without confirming the change in S605, the change history is recorded by the interpretation report work management service 332 as a temporary change history. The change history is recorded in the interpretation work information 351 or the interpretation report status / history information 352.

  FIG. 10 is a diagram exemplifying display of a screen in the above-described process accompanying a change in one item. FIG. 10 is an example of a screen when a change for adding a description to a finding is started after the interpretation report illustrated in FIG. 5 is created. The same reference numerals as those in FIG. 5 are assigned to the same components as those in FIG. 5 such as the window configuration, and the detailed description thereof is omitted here with the aid of the description in FIG.

  In order to add a description to the finding item 1008, the image interpretation doctor 202 clicks and selects the item 1008 using a mouse which is an example of the input device 104 of the PC client 213, for example. Thereby, the process which specifies the change influence range illustrated in FIG. 6 is performed, and the item 1008 is specified as the change influence range. In order to distinguish the identified item 1008 from other items, the display module 342 displays a frame 1016 in the vicinity of the item 1008 based on the input from the change range identifying module 364. The display module 342 displays a character cursor 1017 in the item 1008, and a confirmation button 1018 for performing an operation for confirming the change contents is displayed in the vicinity of the item 1008. The interpretation doctor 202 inputs from the position of the character cursor 1017 and changes the description content of the finding 1008 while moving the character cursor 1017. The process illustrated in FIG. 6 is performed on the change content, and the display indicating the change influence range changes according to the change content.

  FIG. 11 shows an example in which the content displayed on the screen of the display device 109 is changed by the display module 342 in accordance with the input of the changed content. The same components as those in FIGS. 5 and 10 are denoted by the same reference numerals, and the detailed description thereof is omitted here by using the description in FIGS. 5 and 10. FIG. 11A illustrates a screen when the interpretation doctor 202 is inputting the finding item 1108 to which the input content 1119 is added. FIG. 11B illustrates a screen when the interpretation doctor 202 inputs the finding item 1121 to which the input content 1120 is added. FIG. 11C illustrates a screen when a diagnosis item 1127 in which the input content 1125 is added to the diagnosis item is being input.

  In FIG. 11A and FIG. 11B, the input operation of the interpretation doctor and the change in the display on the screen proceed to the input contents and FIG. 11C, and the processing illustrated in FIG. 6 is performed for each input. Based on the input of the change range identification module 364, the display module 342 updates the display of the change influence range. In FIG. 11B, from the change that the image feature name “infiltrated shadow” and the perceptual expression of “acknowledge” are added to the image feature name in the processing of S608 shown in FIG. Detailed change information “addition of feature name expression” is acquired. Accordingly, the rule R910 illustrated in FIG. 9 is applied in the processing of S609 illustrated in FIG. The change influence range is specified as a finding item 1211 and a diagnosis item 509. Thereby, a frame 1122 for displaying the item 1121 and the item 509 separately from the other items is displayed. In FIG. 11C, the image interpretation doctor 202 adds input contents 1125 to the diagnosis items included in the frame 1122 and performs input while moving the character cursor 1126.

  When the description is completed and the interpretation doctor 202 clicks the confirmation button 1123, the screen illustrated in FIG. 12 is displayed by the processing from S613 shown in FIG. The change for adding the input content 1225 to the diagnosis item is confirmed, and the diagnosis item 1226 is displayed. Here, there is no display such as a frame indicating the change influence range in FIG. 10 or FIG. 11 or a character cursor. The same components as those in FIGS. 5, 10, and 11 are denoted by the same reference numerals, and the detailed description is omitted here by using the above description. In this way, when the change is made, the display of the change influence range changes according to the change content, so that the target to be confirmed with the interpretation doctor can be indicated, and occurrence of omission can be reduced.

  FIG. 13 illustrates a screen display in the process illustrated in FIG. 6 according to another example of the change in one item. FIG. 10 is an example of a screen when a change for adding a description to a finding is started after the interpretation report illustrated in FIG. 5 is created. About the same structure as FIG. 5, the same code | symbol as FIG. 5 is attached | subjected and detailed description is abbreviate | omitted here using the description in FIG.

  In order to add a description to the finding item 1308, the image interpretation doctor 202 clicks and selects the item 1008 using a mouse which is an example of the input device 104 of the PC client 213, for example. Thereby, the process for specifying the change influence range illustrated in FIG. 6 is performed, and the item 1308 is specified as the change influence range. In order to distinguish the identified item 1308 from other items, the display module 342 displays a frame 1316 based on the input from the change range identifying module 364. Interpretation doctor 202 performs input to finding 1308 while moving character cursor 1317.

  FIG. 14 illustrates that the content displayed on the screen of the display device 109 is changed by the display module 342 in accordance with the input of the change content. The same components as those in FIGS. 5 and 13 are denoted by the same reference numerals, and detailed descriptions thereof are omitted here with the aid of the descriptions in FIGS. 5 and 13. From FIG. 14A to FIG. 14B and FIG. 14C, the input operation of the interpretation doctor and the change in the display of the screen progress, and the processing illustrated in FIG. 6 is performed for each input. Based on the input from the change range specifying module 364, the display module 342 updates the display of the change influence range. FIG. 14A illustrates a screen when the interpretation doctor 202 inputs the input content 1419 for changing the region name from “upper right lobe” to “upper left lobe” in the finding item 1408. Yes. FIG. 14B illustrates a screen when the change influence range changes according to the change content.

  In the case of FIG. 14B, the medical term of the part name “upper right lobe of the right lung” and “upper lobe of the left lung” after change is obtained in the process of S608 shown in FIG. The change detailed information “change of expression” is acquired. Accordingly, the rule R902 of FIG. 9 is applied in the processing of S609 shown in FIG. As the change influence range, findings item 1408, image 507, diagnosis item 509, finding item 512 associated with these items, and image 511 are specified. FIG. 14C illustrates a screen when the interpretation doctor 202 changes the description of the finding item 1423 included in the change influence range.

  When the description is completed and the image interpretation doctor 202 clicks the confirmation button 1425, the screen illustrated in FIG. 15 is displayed by the processing after S613 shown in FIG. A change to the diagnosis item is confirmed, and a diagnosis item 1512 is displayed. Here, there is no display such as a frame indicating the change influence range and the character cursor in FIGS. The same components as those in FIGS. 5, 13, and 14 are denoted by the same reference numerals, and the detailed description is omitted here by using the above description. In this way, when the change is made, the display of the change influence range changes according to the change content, so that the target to be confirmed with the interpretation doctor can be indicated, and occurrence of omission can be reduced.

  FIG. 16 is an example of display when the entire display cannot be performed due to restrictions on the display size and resolution of the display device 109 in the display for inputting the change and confirming work. The same components as those in FIG. 5 are denoted by the same reference numerals, and detailed description thereof is omitted by using the description of FIG. The range displayed in the display device 109 is changed by an operation input to the scroll bar 1619 and the scroll bar 1620. Further, when the entire interpretation report cannot be displayed, automatic scrolling is performed so that the frame 1616 indicating the change influence range is contained within the screen of the display device 109 as much as possible. The range to be confirmed can be easily recognized in accordance with the change contents input by the image interpretation doctor 202.

  According to the present invention, when an interpretation report is changed, the influence range of the change can be specified in accordance with the change content, and a display suggesting a portion that is likely to be missed can be performed. As a result, it is possible to suppress change leakage and reduce the occurrence of errors in the description content of the interpretation report.

  In the interpretation report creation support apparatus according to the embodiment of the present invention, the display for indicating the item specified as the change influence range is not limited to the display illustrated in the frame 1016 of FIG. For example, by distinguishing by lighting only the frame of the item specified as the change influence range, or by displaying the item frame thickness, the frame color, or the color in the frame in a different color from the unspecified item It may be displayed. FIG. 17A shows a case where the thickness and color of the display frame are used. In the example of FIG. 17A, the finding item 1708 on which the character cursor 1717 is displayed is a changed item. By displaying the frame of the diagnosis item 1709 with a thicker line than the other items as the change influence range specified with the change, the specified item and the unspecified item are displayed separately. Yes.

  Further, when the change work is completed, a change history may be displayed. In the example of FIG. 17B, there are a frame 1748 and a frame 1750 that indicate the change influence range where the change has been completed, and at least change contents, change classification, changer, and change date and time are indicated for each change influence range. . A frame 1748 includes an item 1746 and an item 1747. In each item, the part displayed in bold is the changed content. Further, a change history display 1749 is displayed in the vicinity of the frame 1748. The change history display shows the change classification, the changer, and the change date and time. For example, “change of findings contents / change of diagnosis contents” as the change classification, “Suzuki” as the changer, and “October 10 15:32” as the change date and time are displayed in the change history display 1749. Similarly, a change history display 1751 is displayed near the frame 1750. For example, “change of findings” as the change classification, “Suzuki” as the changer, and “October 10 15:40” as the change date and time are displayed in the change history display 1751. Thus, when there are a plurality of changes and a plurality of change influence ranges are displayed, the change influence ranges for each change may be displayed separately. For example, a frame color indicating a certain change influence range or a color within the frame is displayed in a color different from other change influence ranges. That is, when there are a plurality of changes, the change influence range for each changed item is displayed separately on the display unit. As a result, the user can easily grasp what changes have been made in creating the interpretation report.

  The interpretation report creation support system according to the embodiment of the present invention can be used for other medical documents that explicitly show the logical structure in addition to the interpretation report. For example, the change influence range in a certain interpretation report may be displayed including descriptions in medical documents other than the interpretation report. In another example, a changed item is associated with the changed item and displays the presence of a description in another medical document. Thereby, the user can know the influence of the change to another medical document, and the change leak can be reduced. Furthermore, there is an item associated with a description item in another medical document in a certain interpretation report, and the creator of the interpretation report and the creator of another medical document may be different users. In such a case, a notification prompting the change or confirmation of the medical document is sent to the creator of another medical document. In the notification, the influence of the change to another medical document is transmitted using the structured relationship, and the description part included in the change influence range and the change type information of the changed interpretation report are sent. As a result, the creator of another medical document that has received the notification can know what kind of confirmation / correction needs to be performed.

  In each of the above embodiments, an interpretation report creation support system including a server and a client has been described as an example, but the present invention is not limited to this. The PC client 213 may have various modules included in the server 230 of FIG. For example, the PC client 213 may have a module for realizing the interpretation report work management service 232. At this time, the interpretation work information 351 and the history information 352 are stored in the external storage device 106 of the PC client 213. Further, when a certain amount of information is accumulated, history information may be output to the server 230 using the interpretation report work management service 232 of the server 230. In another example, the PC client 213 may not have the interpretation report editor 341. The PC client 213 outputs the content input by the image interpretation doctor 202 to the server 230. The server 230 that has received the input content reflects the input content as a description of the structured interpretation report by the function of the structuring module 362. The structured module 362 functions as a display output unit that outputs data for causing the PC client 213 to display the contents of the interpretation report being edited. The PC client 213 displays on the display device 109 of the PC client 213 based on the display data received from the server 230. The PC client 213 can display the display data output from the server 230 on the display device 109 by an application such as a web browser.

  The present invention is not limited to interpretation report creation support. When changing the description of a report, depending on the content of the change and the context of the changed part, it is necessary to check whether there is a part that should be changed other than the changed part. This is a common issue.

  For example, information systems used in offices include information sharing systems such as accounting, product inventory management, and document storage / retrieval. In addition, systems that link individual operations such as receipt and payment of payments, procedures such as ordering and ordering goods, delivery, and analysis of sales are increasing. In some cases, such an information system is used to create a report or report that describes the results of analysis based on advanced knowledge and experience, and examination of the response. Reports and reports are often accompanied by electronic data, digital photographs, and images. In order to show the validity of the results of studying analysis and response, it is necessary to logically describe the basis for these analysis and study. For such problems, the structured report creation support of the present invention can be used.
