Description
この発明は、検査依頼に基づき医用画像撮影装置により取得された医用画像に対して、検査目的及び所見文が記述された読影レポートを作成する読影レポート作成支援装置、及び、読影レポート作成支援方法に関し、例えば、Ｘ線コンピュータ断層撮影装置（ＣＴ）や磁気共鳴イメージング装置（ＭＲＩ）などの医用画像撮影装置で撮影された患者の医用画像に対する医学的所見の報告書を作成する読影レポート作成支援端末を中心に、この端末とネットワークで接続された、前記医用画像を保管する医用画像保管装置と、保管された医用画像をユーザに参照させる医用画像参照装置とにより構成された読影レポート作成支援装置、及び、読影レポート作成支援方法に関するものである。 The present invention relates to an interpretation report creation support apparatus and an interpretation report creation support method for creating an interpretation report in which an examination purpose and a finding sentence are described for a medical image acquired by a medical imaging apparatus based on an examination request. For example, an interpretation report creation support terminal for creating a medical observation report for a medical image of a patient taken by a medical imaging apparatus such as an X-ray computed tomography apparatus (CT) or a magnetic resonance imaging apparatus (MRI) An image interpretation report creation support apparatus mainly composed of a medical image storage apparatus that stores the medical image, and a medical image reference apparatus that allows the user to refer to the stored medical image, connected to the terminal via a network, and The present invention relates to an interpretation report creation support method.
従来の技術としては、検査目的を基に、医用画像撮影装置により医用画像を取得し、読影医が、医用画像を医用画像参照装置で観察しながら、読影を行い、検査目的及び所見文が記述された読影レポートを作成する。所見文には、検査目的に対する応答文を含むが、応答文以外の所見も含まれる。 As a conventional technique, based on the purpose of examination, a medical image is acquired by a medical imaging device, and an interpreting doctor interprets the medical image while observing the medical image with a medical image reference device, and describes the purpose of the inspection and the findings. A written interpretation report. The finding sentence includes a response sentence for the inspection purpose, but also includes findings other than the response sentence.
読影医は、応答文の記載漏れがないように、所見文に応答文が含まれるか否かを確認する作業を効率化したいという要望がある。また、診療科医師は、自身が依頼した検査目的に対する応答文が所見文に含まれるか否かを確認する作業を効率化したいという要望がある。 There is a demand for an interpreting doctor to improve the efficiency of checking whether or not a response sentence is included in a finding sentence so that there is no omission in the description of the response sentence. In addition, there is a demand for the medical doctor to improve the efficiency of checking whether or not the response sentence for the examination purpose requested by himself / herself is included in the finding sentence.
前記読影レポートの作成作業を効率化するための従来の技術としては、例えば、画像に含まれる異常の種類と位置を所定の文章に構成するための定型文を記憶する装置と、画像処理で検出された異常の種類及び位置に応じて、前記定型文に基づいて所見文を生成する技術がある（特許文献１）。 Examples of conventional techniques for improving the efficiency of creating the interpretation report include, for example, an apparatus for storing a fixed sentence for configuring the type and position of an abnormality included in an image into a predetermined sentence, and detection by image processing. There is a technique for generating a finding sentence based on the fixed sentence according to the type and position of the abnormality (Patent Document 1).
また、レポートモニタに表示される医用レポートには所見欄が設けられ、所見欄には文字列が配列されている。参照情報モニタには、コンテンツ（医用画像、履歴情報等）が表示されている。文字列にカーソルを合わせてリンクさせたい文字列を特定する。また、コンテンツの中でリンクさせようとするコンテンツを、前記特定された文字列にドラッグアンドドロップすることで、その文字列に、当該コンテンツのアドレス情報をハイパーリンク形式で貼り付ける。同時に、ハイパーリンクが設定された文字列の色を変更し、かつ、下線を付して識別表示する技術がある（特許文献２）。 The medical report displayed on the report monitor is provided with a finding column, and character strings are arranged in the finding column. Content (medical images, history information, etc.) is displayed on the reference information monitor. Place the cursor on the character string and specify the character string to be linked. Also, by dragging and dropping the content to be linked in the content to the specified character string, the address information of the content is pasted to the character string in a hyperlink format. At the same time, there is a technique of changing the color of a character string to which a hyperlink is set and displaying it with an underline (Patent Document 2).
しかしながら、従来の技術では、読影医が作成する所見文には、検査目的に対する応答文以外の所見もあるため、検査依頼をした診療科医師が所見文を確認する際に、検査目的に対する応答文を見つけるのに時間を要するという問題点があった。また、上記特許文献１に記載された技術では、読影医による所見文の作成作業の効率化を図ることができるものの、所見文に応答文が含まれているか否かを確認する作業の効率化を図ることができない。 However, in the conventional technique, the finding sentence created by the interpretation doctor also includes findings other than the response sentence for the examination purpose. Therefore, when the clinician who requested the examination confirms the finding sentence, the response sentence for the examination purpose There was a problem that it took time to find. In addition, although the technique described in Patent Document 1 can improve the efficiency of creating a finding sentence by an interpreting doctor, the efficiency of checking whether or not a response sentence is included in the finding sentence. I can't plan.
さらに、上記特許文献２に記載された技術では、所見欄に記載された文字列に、コンテンツのアドレス情報をハイパーリンク形式で貼り付ける作業の効率化を図ることができるが、所見文に応答文が含まれているか否かを確認する作業の効率化を図ることができないとう問題点があった。 Furthermore, in the technique described in Patent Document 2, it is possible to improve the efficiency of pasting the address information of content in a hyperlink format to the character string described in the finding column. There is a problem in that it is impossible to improve the efficiency of the work of confirming whether or not it is included.
この発明は、上記の問題を解決するものであり、所見文に応答文が含まれているか否かを確認する作業の効率化を図ることが可能な読影レポート作成支援装置、及び、読影レポート作成支援方法を提供することを目的とする。 The present invention solves the above-described problem, and an interpretation report creation support apparatus capable of improving the efficiency of work for confirming whether or not a response sentence is included in a finding sentence, and interpretation report creation The purpose is to provide support methods.

この発明の一の実施形態に係る読影レポート作成支援装置の構成について図１を参照して説明する。図１は、読影レポート作成支援装置を含む画像診断部門システムの機能ブロック図である。 A configuration of an interpretation report creation support apparatus according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a functional block diagram of an image diagnosis department system including an interpretation report creation support apparatus.
画像診断部門システムにおいて、読影レポート作成支援端末１、医用画像保管装置２、医用画像参照装置３、レポートサーバ４、クライアント端末５、ウェブサーバ６、病院情報システム（ＨＩＳ；Ｈｏｓｐｉｔａｌ Ｉｎｆｏｒｍａｔｉｏｎ Ｓｙｓｔｅｍ）７、情報管理システム（ＲＩＳ；Ｒａｄｉｏｌｏｇｙ Ｉｎｆｏｒｍａｔｉｏｎ Ｓｙｓｔｅｍ）８、及び、医用画像撮影装置（モダリティ）９が、ネットワークで相互に接続されている。ここで、読影レポート作成支援装置は、読影レポート作成支援端末１を中心に、それ以外の上記装置又はシステムを１以上組み合わせることにより構成されても良く、読影レポート作成支援端末１単独で構成されても良い。 In the diagnostic imaging department system, an interpretation report creation support terminal 1, a medical image storage device 2, a medical image reference device 3, a report server 4, a client terminal 5, a web server 6, a hospital information system (HIS) 7, information A management system (RIS; Radiology Information System) 8 and a medical image photographing device (modality) 9 are connected to each other via a network. Here, the interpretation report creation support apparatus may be configured by combining one or more of the above-described devices or systems with the interpretation report creation support terminal 1 as the center, or configured by the interpretation report creation support terminal 1 alone. Also good.
診療科医師が患者の容態を勘案しながらＨＩＳ端末７ａで、検査依頼（検査オーダー）を発行する。検査オーダーは電子化され、ネットワークで情報管理システム８に伝達される。撮影技師は、ＲＩＳ端末８ａで検査オーダーを確認し、医用画像撮影装置９で患者を撮影する。それにより、医用画像が生成される。生成された医用画像は、医用情報の標準通信規格であるＤＩＣＯＭ（Ｄｉｇｉｔａｌ Ｉｍａｇｉｎｇ ａｎｄ ＣＯｍｍｕｎｉｃａｔｉｏｎ ｉｎ Ｍｅｄｉｃｉｎｅ）にて医用画像保管装置２に転送され、保管、管理される。 The medical doctor issues an inspection request (inspection order) at the HIS terminal 7a while taking into account the condition of the patient. The inspection order is digitized and transmitted to the information management system 8 via the network. The radiographer confirms the examination order with the RIS terminal 8 a and images the patient with the medical image imaging device 9. Thereby, a medical image is generated. The generated medical image is transferred to the medical image storage device 2 by DICOM (Digital Imaging and Communication in Medicine), which is a standard communication standard for medical information, and stored and managed.
読影医は、転送された医用画像を医用画像参照装置３で観察しながら、読影（医用画像に写っている所見をスクリーニング作業）を行い、その読影時の結果をまとめた読影レポート（報告書）を作成する。読影時には、読影医は診療科医師により示される検査目的を中心に読影を行い、検査目的に対する応答文を記載するが、検査目的に関連する内容以外にも、医用画像に写っている所見については全て記載する。したがって、読影レポートの所見文内には、検査目的に対する応答文以外の文も記載される。作成された読影レポート及び医用画像は、院内画像参照システムを構成する前記ウェブサーバ６に保管される。 The interpretation doctor performs interpretation (screening of findings in the medical image) while observing the transferred medical image with the medical image reference apparatus 3, and interprets the interpretation report (report) that summarizes the results of the interpretation. Create At the time of interpretation, the interpreting doctor interprets mainly the examination purpose indicated by the clinician and writes a response to the examination purpose. In addition to the contents related to the examination purpose, about the findings reflected in the medical image List all. Therefore, sentences other than the response sentence for the inspection purpose are also described in the finding sentence of the interpretation report. The created interpretation report and medical image are stored in the web server 6 constituting the in-hospital image reference system.
診療科医師を含む利用者は、院内に設置されているＨＩＳ端末７ａあるいはクライアント端末５からウェブブラウザを用いて、ウェブサーバ６にアクセスして、保管された医用画像及び読影レポートを簡便に参照することができる。 Users including medical doctors access the web server 6 from the HIS terminal 7a or the client terminal 5 installed in the hospital using the web browser, and simply refer to the stored medical images and interpretation reports. be able to.
次に、主に、レポート作成支援装置の構成について、図２を参照して説明する。図２は、レポート作成支援装置に関わる構成を示した機能ブロック図である。 Next, the configuration of the report creation support apparatus will be mainly described with reference to FIG. FIG. 2 is a functional block diagram showing a configuration related to the report creation support apparatus.
レポート作成支援装置に関わる構成は、レポート保管部１１、検査目的解析部１２、所見文解析部１３、検査目的関連文判定部１４、出力部１５、及び、検査目的関連文表示部１６が含まれる。 The configuration related to the report creation support device includes a report storage unit 11, an inspection purpose analysis unit 12, a finding sentence analysis unit 13, an inspection purpose related sentence determination unit 14, an output unit 15, and an inspection purpose related sentence display unit 16. .
（レポート保管部）
先ず、レポート保管部１１について、図２及び図１６を参照して説明する。図１６は、読影レポートの表示画面を示す図である。
(Report storage department)
First, the report storage unit 11 will be described with reference to FIGS. FIG. 16 is a diagram showing a display screen of an interpretation report.
レポート保管部１１は、読影レポート作成支援装置内に設けられた記憶部であっても良く、読影レポート作成支援装置外に設けられた記憶部であっても良い。レポート保管部１１では、読影レポート作成支援装置で読影医が作成した読影レポートを保管する。読影レポートは、少なくとも診療科医師が記載する検査目的２０と、読影医がその検査の画像の診断を行なった結果を記載した所見文３０を含む。検査目的２０及び所見文３０を含む読影レポートの表示画面を図１６に示す。 The report storage unit 11 may be a storage unit provided in the interpretation report creation support apparatus, or may be a storage unit provided outside the interpretation report creation support apparatus. The report storage unit 11 stores the interpretation report created by the interpretation doctor using the interpretation report creation support apparatus. The interpretation report includes at least the examination purpose 20 described by the medical doctor and the finding sentence 30 describing the result of the diagnosis performed by the interpretation doctor on the image of the examination. A display screen of an interpretation report including the inspection purpose 20 and the finding sentence 30 is shown in FIG.
（検査目的解析部）
次に、検査目的解析部１２について、図２〜図６を参照して説明する。図３は、検査目的種別と形式記述とを対応付けて記憶した対応テーブル、図４は検査目的の形式記述を取得するまでの処理を示すフローチャート、図５は、検査目的の分類毎の特徴語を表した特徴語辞書を示す図、図６は、医学用語分類辞書を示す図である。
(Inspection purpose analysis department)
Next, the inspection purpose analysis unit 12 will be described with reference to FIGS. FIG. 3 is a correspondence table in which the inspection purpose type and the format description are stored in association with each other, FIG. 4 is a flowchart showing a process until acquiring the inspection purpose format description, and FIG. 5 is a feature word for each inspection purpose classification. FIG. 6 is a diagram illustrating a medical term classification dictionary.
図４に示すフローチャートにおいて、検査目的解析部１２が、予め記憶している特徴語辞書４０を参照し、取得した検査目的２０の文章に含まれる文字列が特徴語辞書４０中の特徴語と一致するか否かを検索する。取得した検査目的２０の文章が特徴語を含む場合、取得した検査目的２０の文章を特徴語に対応付けられた検査目的種別に分類する（ステップＳ１０１）。 In the flowchart shown in FIG. 4, the examination purpose analysis unit 12 refers to the feature word dictionary 40 stored in advance, and the character string included in the acquired sentence of the examination purpose 20 matches the feature word in the feature word dictionary 40. Search whether or not to do. When the acquired sentence of the inspection purpose 20 includes a feature word, the acquired sentence of the inspection purpose 20 is classified into an inspection purpose type associated with the feature word (step S101).
これを、取得した検査目的２０の文章が“上肺野の気腫の有無”である一例で説明すると、検査目的２０の文章“上肺野の気腫の有無”に含まれる文字列“有無”が、特徴語４１の“有無”の文字列と一致するので、検査目的解析部１２は、図５の特徴語辞書４０に示す特徴語と検査目的種別との対応関係から、“有無”という特徴語４１に対応関係にある「存在の有無」という検査目的種別４２に、前記検査目的２０の文章を分類する。以下、検査目的種別４２を分類先の検査目的種別という。なお、図５に示す特徴語辞書４０の形式は、この例に限定されない。特徴語は、正規表現のような文字列のパターンでも構わないし、ある語句とある語句が含まれる場合というように共起情報でも構わない。 This will be explained with an example in which the acquired sentence of the examination purpose 20 is “presence / absence of upper lung field emphysema”. The character string “presence / absence” included in the sentence of the examination purpose 20 “presence / absence of emphysema of the upper lung field” "" Matches the character string of "presence / absence" of the feature word 41, the inspection purpose analysis unit 12 calls "presence / absence" from the correspondence between the feature word and the inspection purpose type shown in the feature word dictionary 40 of FIG. The sentence of the inspection purpose 20 is classified into the inspection purpose type 42 “existence / non-existence” that has a correspondence relationship with the feature word 41. Hereinafter, the inspection purpose type 42 is referred to as a classification destination inspection purpose type. Note that the format of the feature word dictionary 40 shown in FIG. 5 is not limited to this example. The feature word may be a character string pattern such as a regular expression, or may be co-occurrence information such as a case where a certain phrase is included.
次に、検査目的解析部１２は、取得した検査目的の文章に含まれる各語句の概念を特定する（ステップＳ１０２）。上記と同様に、取得した検査目的２０の文章が“上肺野の気腫の有無”である一例で説明すると、検査目的解析部１２は、予め記憶している図６に示す医学用語分類辞書５０を参照し、“上肺野の気腫の有無”という検査目的２０の文章中の“肺野”という語句５１から「部位」という概念５２を特定し、また、“気種”という語句５３から「現象」という概念５４を特定する。 Next, the examination purpose analysis unit 12 specifies the concept of each word / phrase included in the acquired examination purpose sentence (step S102). In the same manner as described above, when the acquired sentence of the examination purpose 20 is “presence / absence of upper lung field emphysema”, the examination purpose analysis unit 12 stores the medical term classification dictionary shown in FIG. 50, the concept 52 of “part” is specified from the phrase 51 of “lung field” in the sentence of the examination purpose 20 “presence / absence of emphysema in the upper lung field”, and the phrase 53 of “kind” From this, the concept 54 of “phenomenon” is specified.
次に、検査目的解析部１２は、分類先の検査目的種別４２が有する概念の全部が、検査目的２０の文章中の概念に含まれるか否かを判断し、前記概念の全部が検査目的２０の文章中の概念に含まれると判断した場合に、分類先の検査目的種別４２の形式記述を参照して、検査目的の意味内容を表す検査目的の形式記述を取得する（ステップＳ１０３）。 Next, the inspection purpose analysis unit 12 determines whether or not all of the concepts included in the inspection purpose type 42 of the classification destination are included in the concepts in the sentence of the inspection purpose 20, and all of the concepts are included in the inspection purpose 20. If it is determined that it is included in the concept in the sentence, the format description of the inspection purpose representing the meaning content of the inspection purpose is acquired with reference to the format description of the inspection purpose type 42 of the classification destination (step S103).
上記一例で説明すると、検査目的解析部１２は、分類先の検査目的種別４２が有する概念の全部（図３に示す対応テーブル６０の「部位」という概念６１及び「現象」という概念６２）が、ステップ１０２で特定した、検査目的２０の文章中の概念（「部位」という概念５２、及び、「現象」という概念５４）に含まれるかを判断し、含まれていると判断した場合に、形式記述として“isThere（肺野,気腫）”という記述を取得する。 Explaining in the above example, the inspection purpose analysis unit 12 has the concept of the inspection purpose type 42 of the classification destination (the concept 61 “part” and the concept 62 “phenomenon” in the correspondence table 60 shown in FIG. If it is determined whether it is included in the concept (concept 52 of “part” and concept 54 of “phenomenon”) specified in step 102 in the sentence of the inspection purpose 20, A description “isThere (lung field, emphysema)” is acquired as a description.
検査目的２０での文章の表現方法に違いが存在しても、その意味内容が同じであれば同じ形式記述を取得する。例えば、“上肺野に気腫は存在するか?”という検査目的２０が記載されている場合、“存在するか”という特徴語４３が図５の特徴語辞書４０中の「存在の有無」という検査目的種別４２に属するので、検査目的解析部１２は、この検査目的２０の文章を検査目的種別４２に分類し、形式記述として、前例と同じく“isThere（肺野,気腫）”という記述を取得する。 Even if there is a difference in the expression method of the sentence for the inspection purpose 20, the same format description is acquired if the semantic content is the same. For example, when the examination purpose 20 “is emphysema present in the upper lung field?” Is described, the feature word 43 “is present” is “existence presence / absence” in the feature word dictionary 40 of FIG. Therefore, the examination purpose analysis unit 12 classifies the sentence of the examination purpose 20 into the examination purpose type 42, and the description “isThere (lung field, emphysema)” is the same as the previous example. To get.
以上によれば、表現を変えた文字列が各検査目的２０の文章中に含まれた場合であっても、文字列の意味内容を基に、文字列を概念化し、特徴語辞書４０に登録しておけば、特徴語辞書４０を参照することにより、各検査目的２０の文章を、適正な検査目的種別に分類することが可能となる。 According to the above, even if a character string whose expression is changed is included in the sentence for each inspection purpose 20, the character string is conceptualized based on the semantic content of the character string and registered in the feature word dictionary 40. Then, by referring to the feature word dictionary 40, it is possible to classify the sentences for each inspection purpose 20 into appropriate inspection purpose types.
本実施形態では、検査目的２０の意味内容により、検査目的２０を図３に示す通り８つの種別（存在の有無、性状確認、経時変化確認、部位の特定、病期診断、再発・転移確認、部位精査、その他）に分類したが、検査目的種別の数及び各検査目的種別の内容は、これに限定されるものではない。ここで、特徴語とは、目的とする検査の結論を要求する用語であり、検査目的種別とは、検査目的２０をその意味内容により区別した検査目的２０の種類を示す用語である。また、概念は、検査目的２０の対象物を表すものであり、例えば、「存在の有無」の検査目的種別では、どこの部位にどのような現象の有無を確認するのかを表す、「部位」という概念５２、及び、「現象」という概念５４が与えられる（図３参照）。 In this embodiment, according to the meaning content of the examination purpose 20, the examination purpose 20 is classified into eight types as shown in FIG. 3 (presence / absence, property confirmation, change with time, site identification, staging, recurrence / metastasis confirmation, However, the number of inspection purpose types and the contents of each inspection purpose type are not limited to this. Here, the feature word is a term for requesting a conclusion of the target inspection, and the inspection purpose type is a term indicating the type of the inspection purpose 20 that distinguishes the inspection purpose 20 by its meaning content. The concept represents an object of the inspection purpose 20. For example, in the inspection purpose type of “presence / absence”, “part” that indicates what kind of phenomenon is confirmed in which part. And a concept 54 of “phenomenon” (see FIG. 3).

FIG. 11, FIG. 11 is a diagram showing a medical term dictionary, FIG. 12 is a diagram showing a case adjunct expression dictionary, and FIG. 13 is a correspondence table in which finding sentence types and format descriptions are stored in association with each other.
所見文解析部１３は、読影レポートの所見欄に読影医が記載した各所見文３０から、その意味内容を表す形式記述を取得する。所見文３０の形式記述を取得するまでの処理について、図７に示すフローチャートを参照して説明する。 The finding sentence analysis unit 13 acquires a format description representing the meaning content from each finding sentence 30 described by the interpretation doctor in the finding column of the interpretation report. Processing until the format description of the finding sentence 30 is acquired will be described with reference to a flowchart shown in FIG.
その説明の一例として、“上肺野に気腫像を認める。”という文章が与えられた場合について述べる。 As an example of the explanation, a case will be described in which a sentence “an emphysema image is recognized in the upper lung field” is given.
所見文解析部１３は、予め記憶している図１０に示す述語表現辞書７０を参照し、“上肺野に気腫像を認める。”という文章中の“認める”という文字列が、述語表現辞書７０中の“認める”という表層表現７１と合致するため、文章に、“認める”という述語が含まれると判定し、「認める」というＮｏ．５の述語を特定する（ステップＳ２０１）。 The finding sentence analysis unit 13 refers to the predicate expression dictionary 70 shown in FIG. 10 stored in advance, and the character string “recognize” in the sentence “recognizes an emphysema image in the upper lung field” is predicate expression. Since it matches the surface expression 71 “accept” in the dictionary 70, it is determined that the predicate “accept” is included in the sentence. 5 predicates are identified (step S201).
次に、所見文解析部１３は、所見文３０の文章を構成する格を抽出する（ステップＳ２０２）。まず、前例の文章の形態素解析を行い、形態素に分解する。形態素解析の結果、付属語と解析された形態素から、予め記憶している図１２に示す付属語表現辞書９０に従い、文章に含まれる格を得る。 Next, the finding sentence analysis part 13 extracts the case which comprises the sentence of the finding sentence 30 (step S202). First, the morphological analysis of the sentence of the previous example is performed and decomposed into morphemes. As a result of the morpheme analysis, the case included in the sentence is obtained from the analyzed morpheme and the attached word according to the previously stored attached word expression dictionary 90 shown in FIG.
前例である“上肺野に気腫像を認める。”という文章を形態素に分解した形態素解析結果として「／上＜名＞／肺野＜名＞＋に＜付＞／気腫＜名＞／像＜尾＞＋を＜付＞／認め＜下一＞＋る＜活尾＞／。＜句読＞」を図８に示す。 As a result of the morphological analysis that decomposed the sentence “Recognize emphysema in the upper lung field” into the morpheme, “/ Up <Name> / Lung field <Name> + <Appendix> / Emema <Name> / The image <tail> + is <attached> / recognized <lower one> + ru <live tail> / <punctuation> is shown in FIG.
上記形態素解析結果から分かるように、所見文解析部１３は、付属語として“に”、及び“を”を抽出し、これらの付属語を、図１２の付属語表現辞書９０を参照することにより、ニ格、ヲ格となりえる付属語だと判別し、この結果、前例の文章から、二格として“肺野に”、ヲ格として“気腫を”という文字列を得る。 As can be seen from the morpheme analysis result, the finding sentence analysis unit 13 extracts “ni” and “wo” as an appendix, and refers to the appendix expression dictionary 90 in FIG. As a result, a character string “in the lung field” as the second case and “emphysema” as the case is obtained from the sentence of the previous example.
次に、所見文解析部１３は、予め記憶している図１１に示す医学用語辞書８０を用い、文章に含まれる格の概念を特定する。“上肺野に気腫像を認める。”という前例の文章では、“肺野”という格８１が「部位」という概念８２、“気腫”という格８３が「現象」という概念８４となるため、所見文解析部１３は、前例の文章に「部位」の概念８２、及び、「現象」の概念８４が含まれると特定する（ステップＳ２０３）。次に、図８に示す形態素解析結果の格に対し、前記特定した概念を付加する。概念を付加した結果として「／上＜名＞／肺野（部位）＜名＞＋に＜付＞／気腫（現像）＜名＞／像（画像現象）＜尾＞＋を＜付＞／認め＜下一＞＋る＜活尾＞／。＜句読＞」を図９に示す。また、付加した前記概念を図９に“（”及び、“）”で表したカッコ内に示す。 Next, the finding sentence analysis part 13 specifies the concept of the case contained in a sentence using the medical term dictionary 80 shown in FIG. 11 memorize | stored beforehand. In the precedent sentence, “an emphysema image is recognized in the upper lung field”, the case 81 “lung field” is the concept 82 “part”, and the case 83 “emphysema” is the concept 84 “phenomenon”. The finding sentence analysis unit 13 specifies that the “part” concept 82 and the “phenomenon” concept 84 are included in the precedent sentence (step S203). Next, the identified concept is added to the case of the morphological analysis result shown in FIG. As a result of adding the concept, “/ top <name> / lung field (part) <name> + to <append> / emphysema (development) <name> / image (image phenomenon) <tail> + <append> / "Recognition <lower one> + ru <active tail> /. <Punctuation>" is shown in FIG. Further, the added concept is shown in parentheses indicated by “(” and “)” in FIG.
次に、所見文解析部１３は、図１３に示す対応テーブル１００を参照して、述語と、その述語が取る格と、その格に含まれる概念との関係と、形式記述との関係により、所見文３０の形式記述を取得する（ステップＳ２０４）。“上肺野に気腫像を認める。”という前例の文章では、“認める”という述語が含まれ、二格及びヲ格が含まれ、二格には「部位」の概念、ヲ格には「現象」の概念が含まれる。このことから、前例の文章は、図１３の対応テーブル１００中のＮｏ．３に合致する。それにより、所見文解析部１３は、Ｎｏ．３の形式記述である“ThereIs（肺野,気腫）”を取得する。 Next, the finding sentence analysis unit 13 refers to the correspondence table 100 shown in FIG. 13, according to the relationship between the predicate, the case taken by the predicate, the concept included in the case, and the formal description. The format description of the finding sentence 30 is acquired (step S204). The precedent sentence that “recognizes emphysema in the upper lung field” includes the predicate “recognize” and includes the second case and wo case, the second case includes the concept of “part”, The concept of “phenomenon” is included. From this, the sentence of the previous example is No. in the correspondence table 100 of FIG. 3 is met. As a result, the finding sentence analysis unit 13 is 3. Obtain “ThereIs (lung field, emphysema)” which is the format description of 3.
所見文３０の形式記述として、“ThereIs(肺野，気腫)”という記述を取得したが、検査目的の形式記述と同様に、文章の表現に差異が存在しても、その意味内容が同じであれば同じ形式記述を得る。例えば、所見文３０に、“上肺野に気腫像を認めます”という文章が記載されている場合、“認めます“という表層表現７２が図１０の述語表現辞書７０中の「認める」という述語に属するので、所見文解析部１３は、この所見文３０の文章の形式記述として、前例と同じく“ThereIs（肺野,気腫）”という記述を取得する。 Although the description “ThereIs (lung field, emphysema)” was acquired as the formal description of the finding sentence 30, even if there is a difference in the expression of the sentence, the meaning content is the same as the formal description for the examination purpose. Then get the same formal description. For example, if the finding sentence 30 includes a sentence “recognize emphysema in the upper lung field”, the surface expression 72 “recognize” is “recognizes” in the predicate expression dictionary 70 of FIG. Since it belongs to the predicate, the finding sentence analysis unit 13 acquires the description “ThereIs (lung field, emphysema)” as the previous example as the form description of the sentence of the finding sentence 30.
（検査目的関連文判定部）
次に、検査目的関連文判定部１４について、図２、図１４及び図１５を参照して説明する。図１４は所見文の形式記述に検査目的の形式記述が含まれるか否かを判定する処理を示すフローチャート、図１５は検査目的の形式記述と所見文の形式記述との対応関係を定めた対応関係辞書を示す図である。
(Inspection purpose related sentence determination part)
Next, the examination purpose related sentence determination unit 14 will be described with reference to FIGS. 2, 14, and 15. FIG. 14 is a flowchart showing a process for determining whether or not a format description for an inspection purpose is included in the format description of the observation sentence, and FIG. It is a figure which shows a relational dictionary.
検査目的関連文判定部１４は、検査目的解析部１２により取得された検査目的２０の形式記述及び所見文解析部１３により取得された所見文３０の形式記述を基に、予め記憶している対応関係辞書１１０を参照して、検査目的２０に対して応答文１２０を記載している所見文３０を特定する。 The inspection purpose related sentence determination unit 14 stores the correspondence stored in advance based on the format description of the inspection purpose 20 acquired by the inspection purpose analysis unit 12 and the format description of the finding sentence 30 acquired by the finding sentence analysis unit 13. With reference to the relation dictionary 110, the finding sentence 30 in which the response sentence 120 is described with respect to the examination purpose 20 is specified.
図１５に示す対応関係辞書１１０では、検査目的２０の形式記述と、その形式記述に対して、応答文１２０となり得る所見文３０の形式記述との対応関係が定められている。例えば、対応関係辞書１１０中のＮｏ．１において、“isThere(x,y)”と記述された検査目的２０の形式記述と、“ThereIs(x,y)”と記述された所見文３０の形式記述との対応関係が示されている。 In the correspondence dictionary 110 shown in FIG. 15, the correspondence between the format description of the examination purpose 20 and the format description of the finding sentence 30 that can be the response sentence 120 is defined for the format description. For example, in the correspondence dictionary 110, No. 1 shows the correspondence between the format description of the inspection purpose 20 described as “isThere (x, y)” and the format description of the finding sentence 30 described as “ThereIs (x, y)”. .
検査目的２０に対して応答文１２０を記載している所見文３０を特定するまでの処理を図１４に示すフローチャートを参照して説明する。 Processing until the finding sentence 30 in which the response sentence 120 is written for the examination purpose 20 is specified will be described with reference to the flowchart shown in FIG.
具体例としては、検査目的解析部１２により取得された検査目的２０の形式記述として、“上肺野の気腫の有無”（isThere（肺野,気腫））、所見文解析部１３により取得された所見文３０の形式記述“上肺野に気腫像を認める”（ThereIs（肺野,気腫））を挙げて説明する。 As a specific example, “existence / absence of upper lung field emphysema” (isThere (lung field, emphysema)), obtained by the finding sentence analysis unit 13 as the format description of the test purpose 20 acquired by the test purpose analysis unit 12 The following is a description of the formal description of the observation sentence 30 “There is an emphysema image in the upper lung field” (ThereIs (lung field, emphysema)).
検査目的関連文判定部１４が、検査目的解析部１２により“上肺野の気腫の有無”の検査目的２０から取得された検査目的２０の形式記述（isThere（肺野,気腫））を読み出す（ステップＳ３０１）。検査目的２０に記述されている文が複数文ある場合は、ステップＳ３０１〜Ｓ３０６は、全ての文について行う。 The examination purpose-related sentence determination unit 14 displays the format description (isThere (lung field, emphysema)) of the examination purpose 20 acquired from the examination purpose 20 of “the presence or absence of upper lung field emphysema” by the examination purpose analysis unit 12. Read (step S301). When there are a plurality of sentences described in the inspection purpose 20, steps S301 to S306 are performed for all sentences.
次に、検査目的関連文判定部１４が、所見文解析部１３により“上肺野に気腫を認める”の所見文３０から取得された所見文３０の形式記述（ThereIs（肺野,気腫））を読み出す（ステップＳ３０２）。所見文３０の形式記述の読み出しは、取得された所見文３０の形式記述がなくなるまで繰り返す（ステップＳ３０２〜Ｓ３０５）。 Next, the examination purpose-related sentence determination unit 14 forms the description of the finding sentence 30 obtained from the finding sentence 30 “recognize emphysema in the upper lung field” by the finding sentence analysis unit 13 (ThereIs (lung field, emphysema). )) Is read out (step S302). The reading of the format description of the finding sentence 30 is repeated until there is no longer any format description of the acquired finding sentence 30 (steps S302 to S305).
次に、検査目的関連文判定部１４が、図１５に示す対応関係辞書１１０を参照して、両方の形式記述が予め定められた対応関係を有するか否かを判定する（ステップＳ３０３）。前例では、検査目的２０の形式記述（isThere（肺野,気腫））と、所見文３０が形式記述（ThereIs（肺野,気腫））とが、図１５のＮｏ．１に示す対応関係辞書１１０に定められた、isThere(x,y)という検査目的２０の形式記述と、ThereIs(x,y)２０という所見文３０の形式記述との対応関係に相当する。 Next, the examination purpose related sentence determination unit 14 refers to the correspondence dictionary 110 shown in FIG. 15 and determines whether or not both format descriptions have a predetermined correspondence (step S303). In the previous example, the formal description of the examination purpose 20 (is There (lung field, emphysema)) and the finding sentence 30 are the formal description (ThereIs (lung field, emphysema)). This corresponds to the correspondence between the formal description of the examination purpose 20 called isThere (x, y) and the formal description of the finding sentence 30 called ThereIs (x, y) 20, which is defined in the correspondence dictionary 110 shown in FIG.
両方の形式記述が予め定められた対応関係を有すると検査目的関連文判定部１４が判定した場合（ステップＳ３０３；ＹＥＳ）、出力部１５が、検査目的に対する応答文１２０が有るとの判定結果を後述する検査目的関連文表示部１６に出力する（ステップＳ３０４）。一方、両方の形式記述が予め定められた対応関係を有しないと検査目的関連文判定部１４が判定した場合（ステップＳ３０３；ＮＯ）、出力部１５が、応答文無しの判定結果を検査目的関連文表示部１６に出力する（ステップＳ３０７）。 When the inspection purpose related sentence determination unit 14 determines that both format descriptions have a predetermined correspondence (step S303; YES), the output unit 15 gives a determination result that there is a response sentence 120 for the inspection purpose. It outputs to the examination purpose related sentence display part 16 mentioned later (step S304). On the other hand, when the inspection purpose related sentence determination unit 14 determines that both the format descriptions do not have a predetermined correspondence (step S303; NO), the output unit 15 determines the determination result of no response sentence as the inspection purpose related sentence. It outputs to the display part 16 (step S307).
その後、次の所見文３０の形式記述があるかを判断する。次の所見文３０の形式記述がなれば、読み出しを終了し（ステップＳ３０５）、検査目的の形式記述の読み出しのループ（ステップＳ３０１〜Ｓ３０６）に戻り、次の検査目的２０の形式記述があるかを判断する。次の検査目的２０の形式記述がなれば、読み出しを終了する（ステップＳ３０６）。 Thereafter, it is determined whether there is a format description of the next finding sentence 30. When the format description of the next finding sentence 30 is completed, reading is terminated (step S305), and the process returns to the loop for reading the format description for inspection purpose (steps S301 to S306) to determine whether there is a format description of the next inspection purpose 20. Judging. When the format description of the next inspection purpose 20 is completed, the reading is terminated (step S306).
以上に、検査目的２０の形式記載と所見文３０の形式記載との対応関係の有無を判定し、その判定結果を検査目的関連文表示部１６に出力するまでの処理を、上記具体例を挙げてを説明したが、次に、“動脈瘤サイズチェック”という検査目的２０、及び、“右総腸骨にφ２４ｍｍの動脈瘤を認める”という所見文３０を挙げて説明する。 As described above, the process up to the determination of the presence / absence of the correspondence between the format description of the inspection purpose 20 and the format description of the finding sentence 30 and the output of the determination result to the inspection purpose-related sentence display unit 16 is described above as a specific example. Next, the examination purpose 20 of “aneurysm size check” and the finding sentence 30 of “recognizing an aneurysm of φ24 mm in the right common iliac bone” will be described.
検査目的解析部１２は、“動脈瘤サイズチェック”の検査目的２０から検査目的２０の形式記述（attribute(動脈瘤)）を取得する。また、所見文解析部１３は、“右総腸骨にφ２４ｍｍの動脈瘤を認める”という所見文３０から所見文３０の形式記載（ThereIs(総腸骨,動脈瘤)、Num(動脈瘤,φ２４ｍｍ)となる）を取得する。 The examination purpose analysis unit 12 acquires the format description (attribute (aneurysm)) of the examination purpose 20 from the examination purpose 20 of “aneurysm size check”. In addition, the finding sentence analysis unit 13 describes the form of finding sentence 30 to finding sentence 30 “There is an aneurysm of φ24 mm in the right common iliac bone” (ThereIs (common iliac, aneurysm), Num (aneurysm, φ24 mm ) Becomes).
検査目的２０の形式記述（attribute(動脈瘤)）と、所見文３０の形式記載（ThereIs(総腸骨,動脈瘤)、Num(動脈瘤,φ２４ｍｍ)となる）とが、図１５のＮｏ．２に示す対応関係辞書１１０に定められた、検査目的２０の形式記載（attribute(x)）と、所見文３０の記載形式（num(x,y)）との対応関係に相当する。それにより、両方の形式記述が予め定められた対応関係を有すると検査目的関連文判定部１４が判定し、その判定結果を検査目的関連文表示部１６に出力する。 The format description (attribute (aneurysm)) of the examination purpose 20 and the format description of the finding sentence 30 (ThereIs (general iliac, aneurysm), Num (aneurysm, φ24 mm)) are shown in No. 5 of FIG. This corresponds to the correspondence between the format description (attribute (x)) of the inspection purpose 20 and the description format (num (x, y)) of the finding sentence 30 defined in the correspondence relationship dictionary 110 shown in FIG. Thereby, the inspection purpose related sentence determination unit 14 determines that both format descriptions have a predetermined correspondence, and outputs the determination result to the inspection purpose related sentence display unit 16.
また、図１５の対応関係辞書１１０中のxやyなどの変数間に、包含関係、上位下位概念といった概念関係を定義することも可能である。検査目的２０の形式記述（isThere(x, y)）に対する所見文３０の形式記述（ThereIs(s,y), sはxの部分）と定義することにより、“肺塞栓の有無”という検査目的２０に対して、“肺尖野に塞栓を認める”といった、検査目的２０とまったく同一語句が出現していない所見文３０も、それらの形式記述が予め定められた対応関係を有すると検査目的関連文判定部１４が判定することが可能となる。 It is also possible to define conceptual relationships such as inclusion relationships and upper and lower concepts between variables such as x and y in the correspondence relationship dictionary 110 of FIG. By defining the formal description of the finding sentence 30 (ThereIs (s, y), s is part of x) to the formal description of the examination purpose 20 (isThere (x, y)), the inspection purpose of “presence / absence of pulmonary embolism” For the observation sentence 30 that does not appear exactly the same as the examination purpose 20 such as “recognize an embolus in the pulmonary apex” with respect to 20, the examination purpose-related sentence also indicates that the format description thereof has a predetermined correspondence relationship. The determination unit 14 can make the determination.
