Description

診断補助システム、及び診断補助情報表示方法Diagnostic assistance system and diagnostic assistance information display method
 本開示は、診断補助システム、及び診断補助情報表示方法に関し、例えば、被検者の臓器の機能に関連する診断を補助するための技術に関する。 The present disclosure relates to a diagnostic assistance system and a diagnostic assistance information display method, for example, a technique for assisting diagnosis related to a function of an organ of a subject.
 注意欠如・多動症(Attention Deficit and Hyperactivity Disorders : ADHD)は、代表的な脳機能障害の1つであり、不注意、多動性、衝動性を中核症状とする。従来のADHDの診断方法は、行動観察が中心であり、しばしば医師による主観的な判断となっていた。また、ADHDの治療薬である塩酸メチルフェニデート徐放薬(Methylphenidate:MPH)、アトモキセチン(Atomoxetine:ATX)が脳内でどのように効くか、実際に効いているか、さらに薬の選択や変更、内服量の決定等についても行動観察を基に評価することが多かった。 ● Attention 注意 Deficit and Hyperactivity Disorders: ADHD is one of the typical brain dysfunctions, with inattention, hyperactivity and impulsivity as core symptoms. Conventional methods for diagnosing ADHD focus on behavioral observation, and are often subjectively determined by a doctor. In addition, methylphenidate hydrochloride (MPH), a therapeutic agent for ADHD, and how Atomoxetine (ATX) works in the brain. In many cases, the internal dose was determined based on behavioral observation.
 しかし、行動観察は観察者の主観に頼る評価方法である。従って、ADHDに特徴的な脳機能変化を可視化し、診断や治療効果の客観的評価方法の開発が必要とされていた。例えば、非特許文献1においては、客観的評価のための材料として、ADHD児への薬物治療効果を光脳機能計測で可視化することが示されている。また、非特許文献1及び非特許文献2には、薬の種類や脳の活動内容によって、それぞれの薬特有の脳機能の回復効果があることが明らかにされている。現状では、薬物治療効果の可視化を行う際、通常の光脳機能計測と同様に、例えば、特許文献1に示されるように、測定データの信号波形及び統計値のマップ及び活動領域を示すマップを表示することが多い。 However, behavior observation is an evaluation method that relies on the subjectivity of the observer. Therefore, it has been necessary to develop an objective evaluation method for diagnosis and treatment effect by visualizing changes in brain function characteristic of ADHD. For example, Non-Patent Document 1 shows that, as a material for objective evaluation, visualizing a drug treatment effect on an ADHD child by optical brain function measurement. In addition, Non-Patent Document 1 and Non-Patent Document 2 clarify that there is a recovery effect of the brain function unique to each drug depending on the type of drug and the activity content of the brain. At present, when visualizing the drug treatment effect, as shown in Patent Document 1, for example, as shown in Patent Document 1, a map of a signal waveform and a statistical value of a measurement data and a map showing an active area are displayed, as shown in Patent Document 1. Often displayed.

 しかしながら、これまでの測定結果表示方法及びそれらの組み合わせでは、治療判断及び薬効評価の観点では十分な効果のある表示方法とは言えない。また、特許文献1では被検体(患者)の治療情報とは無関係に測定データをマップ表示しているため、被検体への治療の効果を評価する補助としては十分では無い。このため、医師による治療の判断及び患者による病状把握を促すための効果的な結果表示方法が必要とされている。 However, the conventional measurement result display methods and combinations thereof are not sufficiently effective display methods from the viewpoint of treatment judgment and efficacy evaluation.

To. Measurement data of optical brain function measurement (for example, optical topography method), indices related to drug effects, treatment information, and the like are output or displayed in time series and effectively for doctors, operators, patients, and patient families. Furthermore, time-series information useful for diagnosis by a doctor is output and displayed with high reproducibility to a doctor, an operator, or a subject in an integrated and effective manner depending on treatment information. The treatment information and the brain activity information are displayed simultaneously, and the display ROI corresponding to the presence / absence of the treatment information and past information is optimized. In addition, a display method in which the brain function index and the treatment information of the past multiple times are associated is realized. In the inspection result display according to the implementation system of the present disclosure, the difference value display method is determined by determining whether or not the difference value of the amplitude amount is equal to or greater than a predetermined threshold (a magnitude relationship between the amplitude value and the predetermined threshold) change. The display method includes a background color of the difference value, a font for displaying the numerical value of the difference value, and a character color. Further, the measurement position to be displayed is selected according to the treatment information and the task to be used. Here, the treatment information is medication information including type, amount, and frequency of medicine, treatment history, and examination history including brain activity measurement.

You may have the function to change the measurement position (especially right and left) displayed by left and right handed hand information. It is automatically determined whether there is a data acquisition history in the past, and when there is past data, a plurality of latest past data are displayed simultaneously. In particular, in determining the effect of drugs in attention deficit / hyperactivity disorder (Attention Deficit / DSHyperactivityTRDisorder: ADHD), in addition to the evaluation scale of DSM-IV-TR scaled by behavioral observation of parents and teachers, Based on the index of medicinal efficacy judgment, for example, the temporal change of the brain function index and the temporal change of the treatment information are displayed simultaneously. In addition, although the example which acquires a brain function parameter | index by optical brain function measurement (optical topography etc.) was described here, not only this but the measuring method based on electromagnetic means, such as an electroencephalograph and a magnetoencephalograph, functional magnetic resonance What acquired based on the imaging method (fMRI) may be used.

(Iii) Sequence 303
The measurement unit 107 measures, for example, a biological signal (for example, an optical topography signal) in a state in which a subject who has received medication is performing a given task (task) and a state in which the task is not performed, and an input unit The biological signal is provided via 101. Note that the biological signal is sent to the calculation unit 109 so that it can be identified which part of which subject.
(iv)シーケンス304
 医師やオペレータの指示に基づいて、入力部101は、演算部109に対して解析設定の情報を提供する。ここで解析設定は、どの被検者がどのような課題を実行するかについての情報、及び後述の光トポグラフィ検査報告書に何を表示するかについての情報を含んでいる。なお、本実施形態の場合、計測設定で課題に対応する関心領域(ROI)を指定しているが、解析設定に実行課題に対応する注目部位の情報を含めても良い。また、当該注目部位の情報は、設定された課題に対応して自動的に設定しても良い。
(Iv) Sequence 304
Based on an instruction from a doctor or an operator, the input unit 101 provides analysis setting information to the calculation unit 109. Here, the analysis setting includes information on which subject performs what task, and information on what is displayed in an optical topography inspection report described later. In the case of the present embodiment, the region of interest (ROI) corresponding to the task is specified in the measurement setting, but information on the region of interest corresponding to the execution task may be included in the analysis setting.

FIG. 5 is a flowchart for describing processing until a test result report is displayed, which is executed by the brain function index output device 100 according to the embodiment of the present disclosure.
(i)ステップ501
 演算部109は、データベース104から取得した被検者情報及び治療情報を診断補助情報400に設定する。具体的には、演算部109は、データベース104から、被検者のID、氏名、及び性別等の被検者情報、並びに被検者の治療履歴、今回用いた治療薬や投薬量等の治療情報を取得し、被検者ID401、病院ID402、日付404、氏名405、性別406、誕生日407、治療履歴408、処方箋情報409、及び投与量410のそれぞれの欄に入力する。テーブル形式で情報を保持しない場合には、これらの情報が互いに関連付けられて(例えば、被検者ID401から治療履歴等の情報が直ちに取得できるように)記憶部102内に格納されることになる。
(I) Step 501
The calculation unit 109 sets the subject information and treatment information acquired from the database 104 in the diagnosis auxiliary information 400. Specifically, the calculation unit 109 stores the subject information such as the subject's ID, name, and gender from the database 104, the treatment history of the subject, and the treatments and dosages used this time. Information is acquired and input into each column of the subject ID 401, hospital ID 402, date 404, name 405, gender 406, birthday 407, treatment history 408, prescription information 409, and dose 410. When information is not held in a table format, these pieces of information are associated with each other (for example, information such as treatment history can be immediately acquired from the subject ID 401) and stored in the storage unit 102. .
(ii)ステップ502
 演算部109は、医師或いはオペレータが入力した解析設定を取得し、取得する生体信号の解析方法を設定する。解析設定には、被検者が実行する課題の情報、注目すべき部位もしくは関心領域(ROI)、及び検査結果表示のための条件(例えば、表示解像度、ノイズ除去の有無、過去のデータを同時表示するか否か、検査結果の表示態様を示す表示設定情報等)等が含まれる。上述したように、演算部109は、課題の情報に基づいて、それに対応する注目すべき部位を特定しても良い。
(Ii) Step 502
The calculation unit 109 acquires analysis settings input by a doctor or an operator, and sets the analysis method of the acquired biological signal. In the analysis settings, information on the subject to be executed by the subject, a region to be noticed or region of interest (ROI), and conditions for displaying the test result (for example, display resolution, presence / absence of noise removal, past data) Whether or not to display, display setting information indicating a display mode of the inspection result, and the like). As described above, the calculation unit 109 may identify a notable part corresponding to the information based on the task information.
(iii)ステップ503
 演算部109は、被検者が行った課題の結果を課題部105から取得する。課題の結果(課題実行結果)には、課題の種類、被検者の課題に対する反応時間、及び被検者の課題に対する正答率等が含まれる。
(Iii) Step 503
The calculation unit 109 acquires the result of the task performed by the subject from the task unit 105. The result of the task (task execution result) includes the type of task, the reaction time for the subject's task, the correct answer rate for the subject's task, and the like.
(iv)ステップ504
 演算部109は、測定部107から被検者の生体信号を取得し、診断補助情報400に設定する。より具体的には、演算部109は、測定部107から被検者情報(例えば、被検者ID)とともにそれに関連付けられた測定結果である生体信号や測定日の情報を取得する。そして、演算部109は、同じ被検者IDや日付に対応する生体信号412の欄に生体信号を入力する。テーブル形式で情報を保持しない場合には、被検者IDと生体信号が互いに関連付けられて(例えば、被検者IDから生体信号が直ちに取得できるように)記憶部102内に格納されることになる。
(Iv) Step 504
The calculation unit 109 acquires the biological signal of the subject from the measurement unit 107 and sets it in the diagnostic auxiliary information 400. More specifically, the calculation unit 109 acquires from the measurement unit 107 information on a biological signal and measurement date that are measurement results associated with the subject information (for example, a subject ID). And the calculating part 109 inputs a biological signal into the column of the biological signal 412 corresponding to the same subject ID and date. When the information is not held in a table format, the subject ID and the biological signal are associated with each other (for example, the biological signal can be immediately acquired from the subject ID) and stored in the storage unit 102. Become.
(v)ステップ505
 演算部109は、取得した生体信号を解析する。例えば、生体信号にフィルタを掛けてノイズを除去したり、被検者が課題を実行している時間、及び実行していない時間における生体信号を用いた統計解析を行ったりする。統計解析に関し、より具体的には、演算部109は、例えば、複数回実行される課題の結果に対し、対象の被検者の特定の時間におけるデータの平均値を算出する。また、演算部109は、例えば、被検者が課題を実行している時間帯と安静にしている時間帯における生体信号の差分値もしくは比を算出する。さらに、演算部109は、治療薬投与前後の生体信号の差分値もしくは比を算出しても良い。解析結果は、診断補助情報400の1つとして登録しても良い。
(V) Step 505
The calculation unit 109 analyzes the acquired biological signal. For example, the biological signal is filtered to remove noise, or statistical analysis is performed using the biological signal during the time when the subject is executing the task and when the subject is not executing the task. More specifically, regarding the statistical analysis, the calculation unit 109 calculates an average value of data at a specific time of the subject subject, for example, with respect to a result of a task executed a plurality of times. Moreover, the calculating part 109 calculates the difference value or ratio of the biosignal in the time slot | zone when the subject is performing the task, and the time slot | zone which is resting, for example. Further, the calculation unit 109 may calculate a difference value or a ratio of biological signals before and after administration of the therapeutic agent. The analysis result may be registered as one of the diagnostic auxiliary information 400.
(vi)ステップ506
 演算部109は、被検者が課題を実行し、得られた生体信号を解析した後、データベース104における被検者情報及び治療情報を更新する。対象となる被検者が初めて投薬され、課題を実行した場合には、以前当該被検者の情報及び治療情報はデータベース104に登録されていない。また、対象となる被検者が以前投薬され、課題を実行したことがある場合であっても、今回の測定結果や治療情報はまだデータベース104には登録されていない。そこで、演算部109は、新たに得られた情報やデータをデータベース104に登録し、被検者情報及び治療情報を更新する。
(Vi) Step 506
The calculation unit 109 updates the subject information and treatment information in the database 104 after the subject executes the task and analyzes the obtained biological signal. When the subject subject is administered for the first time and the task is executed, the subject information and treatment information have not been registered in the database 104 before. Further, even if the subject subject has been previously administered and has performed the task, the current measurement results and treatment information are not yet registered in the database 104. Therefore, the calculation unit 109 registers newly obtained information and data in the database 104, and updates the subject information and the treatment information.
(vii)ステップ507
 演算部109は、対象の被検者に関し、今回の生体信号(光脳機能計測信号)の測定が初回か否か判断する。初回か否かは被検者情報がデータベース104に登録されておらず、新たに作成したか否かによって判定することができる。初回の場合(ステップ507でYesの場合)には、処理はステップ510に移行する。以前にも測定したことがある場合(ステップ507でNoの場合)には、処理はステップ508に移行する。
(Vii) Step 507
The calculation unit 109 determines whether or not the current measurement of the biological signal (optical brain function measurement signal) is the first time for the subject. Whether or not it is the first time can be determined based on whether or not the subject information is registered in the database 104 and is newly created. In the first case (Yes in step 507), the process proceeds to step 510. If it has been measured before (No in step 507), the process proceeds to step 508.
(viii)ステップ508
 演算部109は、入力された解析設定に含まれる複数データ(過去の測定データ)同時表示設定の有無の情報に基づいて、今回の表示が複数データを同時に表示するものか否か判断する。複数データ同時表示設定である場合(ステップ508でYesの場合)、処理はステップ509に移行する。複数データ同時表示設定ではない場合(ステップ508でNoの場合)、処理はステップ510に移行する。
(Viii) Step 508
The calculation unit 109 determines whether or not the current display displays a plurality of data at the same time based on information on whether or not a plurality of data (past measurement data) simultaneous display settings are included in the input analysis settings. If the multiple data simultaneous display setting is selected (Yes in step 508), the process proceeds to step 509. If the multiple data simultaneous display setting is not set (No in step 508), the process proceeds to step 510.
(ix)ステップ509
 演算部109は、当該被検者の過去のデータ(例えば、以前測定された生体信号やそのときの治療情報等)をデータベース104、或いは診断補助情報400から取得する。
(Ix) Step 509
The calculation unit 109 acquires past data (for example, previously measured biological signals and treatment information at that time) from the database 104 or the diagnostic auxiliary information 400.
(x)ステップ510
 演算部109は、今回測定された生体信号、解析結果(例えば、算出した平均値や差分値)、被検者情報、必要に応じて過去の測定された生体信号等、及び医師やオペレータによって入力された表示設定情報を、出力部103を介して表示部106に提供する。表示部106は、当該表示設定情報に基づいて、生体信号、解析結果、被検者情報等を画面にレイアウトし、表示する。
(X) Step 510
The calculation unit 109 inputs the biological signal measured this time, the analysis result (for example, the calculated average value or difference value), the subject information, the biological signal measured in the past as necessary, and the doctor or operator. The displayed display setting information is provided to the display unit 106 via the output unit 103. Based on the display setting information, the display unit 106 lays out and displays biological signals, analysis results, subject information, and the like on the screen.
 <検査結果表示(デフォルト)の構成例>
 図6は、本実施形態による検査結果表示(光トポグラフィ検査報告書)の初期設定(デフォルト)構成(例)600を示す図である。
<Examination result display (default) configuration example>
FIG. 6 is a diagram showing an initial setting (default) configuration (example) 600 of the inspection result display (optical topography inspection report) according to the present embodiment.
 検査結果表示の初期設定構成600は、被検者情報表示領域601と、プローブ配置表示領域602と、波形表示領域603と、統計データ表示領域604と、コメント記載欄605と、参考情報表示領域606と、関係者等情報表示領域607と、を構成項目として含んでいる。検査結果表示をこのような構成にすることにより、課題及び治療情報に応じた領域表示を設定することができ、医師の診断を補助することができるようになる。 The initial setting configuration 600 for displaying the examination result includes a subject information display area 601, a probe arrangement display area 602, a waveform display area 603, a statistical data display area 604, a comment description column 605, and a reference information display area 606. And a related person information display area 607 as configuration items. By configuring the test result display in such a configuration, it is possible to set a region display according to the problem and the treatment information, and to assist a doctor's diagnosis.
 被検者情報表示領域601は、被検者ID、被検者氏名、被検者の年齢、被検者の性別、被検者の利き手、被検者の生年月日、検査日、被検者が実行した検査課題、検査コメント等を表示するための領域である。さらに、被検者情報表示領域601は、ファイルから被検者の情報を読み込むためのファイル選択ボタンを備えている。図7を用いて後述するように、被検者情報表示領域601に表示する項目については適宜変更可能となっている。 A subject information display area 601 includes a subject ID, a subject name, a subject's age, a subject's gender, a subject's dominant hand, a subject's date of birth, an examination date, and a subject.

A plurality of channel displays 6021 indicate a part (region: channel) from which a biological signal (for example, a signal indicating increase or decrease of detection light) is acquired, and can be appropriately selected as a region of interest by a doctor or an operator (for example, the type of task) And the type of therapeutic agent administered). In this embodiment, 22 channels are set, and when the prefrontal cortex and parietal lobe are targeted, the channels to be noted may be determined in advance. The light source probe 6022 emits near-infrared light to measure the active state of the cerebral cortex. The light detection probe 6023 detects reflected light when near infrared light irradiated on the scalp returns to the scalp again. Since the hemoglobin concentration is known by the increase / decrease of the detection light, the blood volume in the cerebral cortex is known, and the active state of the brain can be measured. Note that an illustration (a method for displaying the face portion) may be superimposed on the MRI structure image to obtain a 3D display, or a dedicated image in which the state of probe mounting on the temporal region can be easily understood. In the initial setting, the number of light sources, the number of detectors, and the arrangement thereof are determined in advance. However, the doctor or the operator can display the number of light sources and the number of detectors displayed in the probe arrangement display area 602. May be set arbitrarily.
 波形表示領域603は、選択された領域における、生体信号の平均値の波形、或いは差分平均値の波形を表示する領域である。初期設定(デフォルト)では、領域1の生体信号の差分平均値の波形が示される。波形表示領域603に表示される波形についても医師或いはオペレータによって適宜選択可能になっている。ここでは生体信号の平均値の波形について述べたが、これに限らず、生体信号の所定期間の積分値、重心値、傾き、所定波形や複数の所定期間における波形間相関値、等を表示しても良い。 The waveform display area 603 is an area for displaying the waveform of the average value of the biological signal or the waveform of the difference average value in the selected area. In the initial setting (default), the waveform of the difference average value of the biological signals in region 1 is shown. The waveform displayed in the waveform display area 603 can be appropriately selected by a doctor or an operator. Although the waveform of the average value of the biological signal has been described here, the present invention is not limited to this, and the integral value, centroid value, inclination, predetermined waveform or correlation value between a plurality of predetermined periods of the biological signal, etc. are displayed. May be.
 統計データ表示領域604は、選択された領域(チャンネル)における、算出された統計データを示す領域である。被検者は、1回の検査において同じ課題を複数回実行する。そのため、1回の検査において取得された複数の生体信号の平均値を算出し、それを対応する検査の測定結果としている。統計データ表示領域604においてS(Stimulation)の値が課題実行中に計測された生体信号の平均値を示し、B(Base line)の値が課題を実行していない休憩中に計測された生体信号の平均値を示している。Sがある1日の検査における投薬後の計測(Bの計測後に服薬し、少なくとも1.5h以上経過後)を表し、Bが投薬前の計測を表すとして、Sの値がある1日における投薬後の課題実行中に計測された生体信号の平均値を示し、Bの値が投薬前の課題実行中に計測された生体信号の平均値を示すようにしても良い。また、B1及びS1が1回目の検査に対応し、B2及びS2が2回目の検査に対応する。差分平均値は、1回の検査における、課題実行前後の生体信号の差分の平均値、或いは治療薬を投与する前後の生体信号の差分の平均値を示している。ここでは生体信号の差分の平均値について述べたが、これに限らず、複数の生体信号間の相関値や比の平均値、生体信号の積分値の差分値、重心値の差分値、傾きの差分値であっても良い。 The statistical data display area 604 is an area showing the calculated statistical data in the selected area (channel). The subject performs the same task a plurality of times in one examination. Therefore, an average value of a plurality of biological signals acquired in one test is calculated and used as a measurement result of the corresponding test. In the statistical data display area 604, the value of S (Stimulation) indicates the average value of the biological signal measured during the task execution, and the value of B (Base line) is the biological signal measured during the break when the task is not executed. The average value is shown. S represents the measurement after medication in a day test (taken after measurement of B, at least 1.5 hours or more), and B represents the measurement before medication, and S represents the measurement before medication. The average value of the biological signal measured during the execution of the task may be shown, and the value of B may indicate the average value of the biological signal measured during the execution of the task before medication. B1 and S1 correspond to the first inspection, and B2 and S2 correspond to the second inspection. The difference average value indicates the average value of the difference between the biological signals before and after the execution of the task or the average value of the difference between the biological signals before and after the administration of the therapeutic agent in one examination. Although the average value of the difference between the biological signals has been described here, the present invention is not limited to this, and the average value of the correlation values and ratios between the plurality of biological signals, the difference value of the integral value of the biological signal, the difference value of the centroid value, the slope It may be a difference value.

 <検査結果表示のレイアウト設定>
 図8は、本実施形態による、検査結果表示のレイアウト設定画面の構成例を示す図である。当該レイアウト設定画面800は、例えば、図6の初期設定の画面で「レポート画面レイアウト」を押下するとポップアップ表示される。
 レイアウト設定画面800は、レイアウト編集可能領域表示部801と、表示内容設定部802と、カットオフ設定部803と、を構成項目として含んでいる。
<Inspection result display layout settings>
FIG. 8 is a diagram illustrating a configuration example of a layout setting screen for inspection result display according to the present embodiment. The layout setting screen 800 is displayed as a pop-up when “Report Screen Layout” is pressed on the initial setting screen of FIG. 6, for example.
The layout setting screen 800 includes a layout editable area display unit 801, a display content setting unit 802, and a cutoff setting unit 803 as configuration items.
 レイアウト編集可能領域表示部801は、被検者情報表示領域から関係者等情報表示領域までの領域が画面上でどのようにレイアウトされるかを示している。図8の例では、被検者情報表示領域と関係者等情報表示領域について固定領域として表示内容を変更できないようになっており、その他の領域については任意の内容に設定可能になっている。また、「大」領域は、被検者情報表示領域の下に設けられる。「大」領域と関係者等情報表示領域の間に、画面1から画面4までの4つの領域が配置されるようになっている。 The layout editable area display unit 801 indicates how the area from the subject information display area to the information display area for related parties is laid out on the screen. In the example of FIG. 8, the display contents cannot be changed as fixed areas for the subject information display area and the related person information display area, and the other areas can be set to arbitrary contents. The “large” area is provided below the subject information display area. Four areas from screen 1 to screen 4 are arranged between the “large” area and the information display area for related parties.
 内容表示設定部802は、検査結果表示を構成する各領域において表示すべき内容を医師やオペレータが選択するためのツールである。医師やオペレータは、内容表示設定部802を用いて、レポートの種類を入力すると共に、「大」領域、及び画面1乃至画面4の表示内容を入力することができる。図8では、プルダウンメニューによって入力内容を選択できるように構成されているが、医師等が直接入力できるようにしても良い。 The content display setting unit 802 is a tool for the doctor or operator to select the content to be displayed in each area constituting the test result display. A doctor or an operator can use the content display setting unit 802 to input the type of report and also input the “large” area and the display contents of the screens 1 to 4. In FIG. 8, the input content can be selected by a pull-down menu, but a doctor or the like may directly input.
 カットオフ設定部803は、例えば、治療薬が被検者に効果があったか否かを示すための閾値を設定するためのツールである。生体信号(平均値や差分平均値)の振幅値が閾値以上であれば治療薬が被検者に効果的であったことを意味し、閾値未満の場合には効果が小さかったことを意味する。このようにすることにより、検査結果報告表示おける統計データ表示領域604において、生体信号(平均値や差分平均値)が設定された閾値以上の場合にはその旨が分かるようなデータ表示形態(例えば、該当する欄の背景を赤く表示する)とすることが可能となる。また、カットオフ設定部803は治療薬の効果に限らず、測定結果をあらかじめ設定された分類(例えば,分類A,分類B)に分けるための境界値(閾値)として設定するためのツールとして用いることも可能である。 Cut-off setting unit 803 is a tool for setting a threshold value for indicating, for example, whether or not a therapeutic drug has an effect on a subject. If the amplitude value of the biological signal (average value or difference average value) is equal to or greater than the threshold value, it means that the therapeutic agent is effective for the subject, and if it is less than the threshold value, the effect is small. . By doing in this way, in the statistical data display area 604 in the test result report display, when the biological signal (average value or difference average value) is equal to or higher than the set threshold value, a data display form (for example, that can be understood) , The background of the corresponding column is displayed in red). The cut-off setting unit 803 is not limited to the effect of the therapeutic agent, and is used as a tool for setting the measurement result as a boundary value (threshold value) for dividing the measurement result into preset classifications (for example, classification A and classification B). It is also possible.
 <ファイル選択画面の構成>
 図9は、本実施形態によるファイル選択画面の構成例を示す図である。ファイル選択画面900は、例えば、初期起動画面(図6)において「ファイル選択」のアイコンを押下することにより表示される。このファイル選択画面900を用いることにより、検査結果表示する対象データを選択することができる。例えば、被検者ID、姓、名、性別、生年月日、IDコメントの何れか1つ以上の項目に検索したい情報を入力すると、入力された項目に対応するデータが表示され、医師やオペレータは、そのうち1つを選択することができる。
<Configuration of file selection screen>
FIG. 9 is a diagram showing a configuration example of a file selection screen according to the present embodiment. The file selection screen 900 is displayed, for example, by pressing the “file selection” icon on the initial startup screen (FIG. 6). By using this file selection screen 900, it is possible to select target data to display the inspection result. For example, when information to be searched is input to one or more items of a subject ID, surname, first name, gender, date of birth, and ID comment, data corresponding to the input item is displayed, and a doctor or operator Can select one of them.
 想定される使用方法としては、例えば、1日目(初診時)の計測データに対し検査結果表示(検査報告書)を作成した後、同被検者の2日目(投薬後2週間経過)の計測データを1日目データに追加して検査報告書を作成する、といった使用形態である。従って、2日目の計測データに関する検査報告書を作成する際に、ファイル選択画面を用いて1日目のデータを取得することができる。このようにすることにより、過去データの参照を自動化することができ、医師やオペレータの手間を削減できる等の効果が期待できる。また、複数日の計測データを容易に比較できるという効果が期待できる。 As an assumed usage method, for example, after creating a test result display (test report) for the measurement data on the first day (at the first visit), the second day of the subject (two weeks after administration) The measurement data is added to the first day data to create an inspection report. Therefore, when the inspection report related to the measurement data on the second day is created, the data on the first day can be acquired using the file selection screen. By doing so, it is possible to automate the reference of past data and to expect effects such as reduction of the labor of doctors and operators. Moreover, the effect that the measurement data of multiple days can be compared easily can be expected.
 <関心領域(ROI)の設定処理>
 図10は、本実施形態による関心領域(ROI)の設定処理を説明するためのフローチャート例である。
<Region of interest (ROI) setting process>
FIG. 10 is a flowchart illustrating the region of interest (ROI) setting process according to the present embodiment.
(i)ステップ1001
 医師或いはオペレータが入力部101を用いて初期設定画面(図6)の「表示」を押下すると、演算部109が「表示」の押下を検知し、図11に示されるパラメータ設定画面1100を表示する。
(I) Step 1001
When the doctor or operator presses “display” on the initial setting screen (FIG. 6) using the input unit 101, the calculation unit 109 detects the press of “display” and displays the parameter setting screen 1100 shown in FIG. .
 パラメータ設定画面1100は、表示パラメータ設定部1101と、解析パラメータ設定部1102と、関心領域設定ボタン1103と、再解析ボタン1104と、を備えている。表示パラメータ設定部1101は、表示すべき生体信号の波形のレンジを設定するためのツールである。図11においては、ヘモグロビンの濃度変化の最大値を0.5、最小値を-0.5とするように設定されている。 The parameter setting screen 1100 includes a display parameter setting unit 1101, an analysis parameter setting unit 1102, a region of interest setting button 1103, and a reanalysis button 1104. The display parameter setting unit 1101 is a tool for setting the waveform range of the biological signal to be displayed. In FIG. 11, the maximum value of hemoglobin concentration change is set to 0.5, and the minimum value is set to −0.5.
 解析パラメータ設定部1102は、生体信号のどの時間区間を解析対象とするか設定するためのツールである。解析においては、例えば課題が複数回繰り返して呈示される場合、時系列データを各課題区間(ブロック)に分割し加算平均化処理することで、課題に同期した信号を抽出することが行われる。その上で、例えば、「課題区間」が選択されると、上記ブロックにおける時間範囲(解析区間)が、あらかじめ測定部107で測定時に設定された課題区間に自動で設定される。ここでは、例えば測定ブロック開始後17秒から38秒までの生体信号を解析対象とするように設定される。つまり、「課題区間」の場合、解析区間は固定区間として設定される。また、図示されてはいないが、「全区間」を選択すると全ブロック区間が解析区間として自動で設定され、「任意区間」を選択すると、医師やオペレータは解析区間を数値入力して自由に設定することができるようになっている。 The analysis parameter setting unit 1102 is a tool for setting which time section of the biological signal is to be analyzed. In the analysis, for example, when a task is repeatedly presented, a time-sequential data is divided into task sections (blocks) and an averaging process is performed to extract a signal synchronized with the task. In addition, for example, when “task section” is selected, the time range (analysis section) in the block is automatically set to the task section set at the time of measurement by the measurement unit 107 in advance. Here, for example, a biological signal from 17 seconds to 38 seconds after the start of the measurement block is set as an analysis target. That is, in the case of “task section”, the analysis section is set as a fixed section. In addition, although not shown in the figure, if “all sections” is selected, all block sections are automatically set as analysis sections. If “any section” is selected, doctors and operators can freely set the analysis sections by entering numerical values. Can be done.
 関心領域設定ボタン1103は、当該ボタンを押下して関心領域設定画面(図12)に移行するためのボタンである。関心領域設定画面を用いて解析対象のチャンネル(領域)を設定することができるようになる。 The region-of-interest setting button 1103 is a button for moving to the region-of-interest setting screen (FIG. 12) by pressing the button. An analysis target channel (region) can be set using the region of interest setting screen.
 再解析ボタン1104は、例えば、パラメータを変更した場合に押下し、変更したパラメータで再度解析の実行を指示するためのボタンである。 The re-analysis button 1104 is, for example, a button that is pressed when a parameter is changed and instructs execution of analysis again with the changed parameter.
(ii)ステップ1002
 演算部109は、医師やオペレータが図11のパラメータ設定画面を用いて設定された、生体信号波形を表示するグラフのレンジの設定、及び解析対象区間の設定を取得(受信)し、検査結果表示に反映する。
(Ii) Step 1002
The calculation unit 109 acquires (receives) the setting of the graph range for displaying the biological signal waveform and the setting of the analysis target section set by the doctor or operator using the parameter setting screen of FIG. To reflect.
(iii)ステップ1003
 演算部109は、医師やオペレータによって別途設定入力されたプローブの光源数及び検出器数、もしくはプローブ配置の情報に基づいて、光源及び検出器をイラスト上に表示する。例えば、設定された光源及び検出器はなるべく等間隔になるように配置される。
(Iii) Step 1003
The calculation unit 109 displays the light source and the detector on the illustration based on the information on the number of probe light sources and the number of detectors or probe arrangement separately set and input by a doctor or an operator. For example, the set light sources and detectors are arranged at equal intervals as much as possible.
(iv)ステップ1004
 演算部109は、医師やオペレータによって関心領域設定ボタン1103が押下されたことを検知すると、例えば、図12に示される関心領域設定画面1200をポップアップ表示する。
(Iv) Step 1004
When the calculation unit 109 detects that the region of interest setting button 1103 has been pressed by a doctor or operator, for example, the calculation unit 109 pops up the region of interest setting screen 1200 shown in FIG.
 関心領域設定画面1200は、関心領域(チャンネル)選択部1201と、関心領域登録部1202と、を備えている。関心領域選択部1201では、3つの領域を選択できるように示されているが、3つ以上であっても良い。関心領域設定部1201は、プローブ配置領域602において、解析対象チャンネルとして設定する領域を選択するためのツールである。関心領域登録部1202は、解析対象チャンネルとして選択された領域1乃至3の組み合わせに名称を付けて登録するためのツールである。解析対象チャンネルとして登録される領域の数は治療薬や課題の種類によって変動してもよく、常に3つの領域がセットで登録されるわけではなく、1つの場合もあれば2つの場合もある。 The region of interest setting screen 1200 includes a region of interest (channel) selection unit 1201 and a region of interest registration unit 1202. Although the region of interest selection unit 1201 is shown so that three regions can be selected, it may be three or more. The region-of-interest setting unit 1201 is a tool for selecting a region to be set as an analysis target channel in the probe placement region 602. The region-of-interest registration unit 1202 is a tool for naming and registering combinations of regions 1 to 3 selected as analysis target channels. The number of regions registered as analysis target channels may vary depending on the therapeutic agent and the type of problem, and the three regions are not always registered as a set, and may be one or two.
(v)ステップ1005
 医師やオペレータが関心領域設定画面1200上で解析対象チャンネルとして設定する領域1乃至3の何れかの領域ボタンを選択すると、演算部109は、プローブ配置領域602の複数のプローブ及びチャンネルが配置された臓器(脳)もしくはその表面のイラストを表示する。そして、医師やオペレータが当該イラスト上で上述の選択された領域(領域1乃至3の何れか1つの領域)として登録すべきチャンネルを例えばマウス(入力部101に相当)操作で設定すると、演算部109はその設定を検知し、選択された領域として登録すべきチャンネルの位置の情報を図示しないメモリに一旦格納する。このような動作が繰り返され、必要とされる全ての領域が解析対象チャンネルとして設定されると、処理はステップ1006に移行する。
(V) Step 1005
When the doctor or operator selects any one of the region buttons 1 to 3 to be set as the analysis target channel on the region-of-interest setting screen 1200, the calculation unit 109 arranges a plurality of probes and channels in the probe placement region 602. Displays an illustration of the organ (brain) or its surface. When a doctor or an operator sets a channel to be registered as the above-described selected region (any one of regions 1 to 3) on the illustration, for example, by a mouse (corresponding to the input unit 101) operation, the calculation unit 109 detects the setting and temporarily stores information on the position of the channel to be registered as the selected area in a memory (not shown). When such an operation is repeated and all the required areas are set as analysis target channels, the process proceeds to step 1006.
 なお、ここでは臓器のイラスト上に表示されたプローブ及びチャンネル配置から1つのチャンネルを選択することにより解析対象チャンネルを設定するようにしているが、この形態には限られない。例えば、設定された全てのチャンネルの波形を描画する画面を表示し、波形を医師やオペレータに選択させることによって解析対象チャンネルを設定しても良い。 Note that, here, the analysis target channel is set by selecting one channel from the probe and channel arrangement displayed on the organ illustration, but this is not a limitation. For example, the analysis target channel may be set by displaying a screen for drawing the waveforms of all the set channels and allowing the doctor or operator to select the waveforms.
(vi)ステップ1006
 医師やオペレータが関心領域登録部1202に解析対象チャンネルとして設定する領域1乃至3の組み合わせの登録名称を入力し、「保存」ボタンを押下すると、演算部109は、当該領域の組み合わせを例えば記憶部102に登録する。このように解析対象チャンネルの組み合わせを登録しておくことにより、同様な検査を行う場合や別のレポート作成をするような場合に、解析対象チャンネルを再度設定する必要がなくなると共に容易に同一領域を設定することができるので、利用者にとっては非常に便利である。
(Vi) Step 1006
When a doctor or an operator inputs a registered name of a combination of regions 1 to 3 to be set as an analysis target channel in the region of interest registration unit 1202 and presses a “save” button, the calculation unit 109 stores the combination of the regions, for example, a storage unit 102. By registering the combination of analysis target channels in this way, it is not necessary to set the analysis target channel again when performing the same inspection or creating another report, and easily set the same area. Since it can be set, it is very convenient for the user.
 <カスタマイズされた検査結果表示の構成例>
 図13は、医師やオペレータによって初期設定検査結果表示(図6参照)がカスタマイズでされた検査結果表示の構成例を示す図である。検査結果表示は、初期設定検査結果表示(図6)が表示された後に、図7乃至12で説明した動作が実行されることによってカスタマイズされる。図13は一例であり、医師やオペレータによる選択が異なればレイアウトや各領域に表示される情報は異なってくるものである。図13に示される検査結果表示では、被検者情報、表示パラメータ(ヘモグロビン変化の軸範囲)、及び関心領域設定がカスタマイズされている。
<Configuration example of customized inspection result display>
FIG. 13 is a diagram illustrating a configuration example of a test result display in which the initial test result display (see FIG. 6) is customized by a doctor or an operator. The inspection result display is customized by executing the operations described with reference to FIGS. 7 to 12 after the initial setting inspection result display (FIG. 6) is displayed. FIG. 13 is an example, and the layout and information displayed in each area differ depending on the selection by the doctor or operator. In the test result display shown in FIG. 13, the subject information, display parameters (axis range of hemoglobin change), and region of interest setting are customized.
 図13において、カスタマイズされた検査結果表示1300は、例えば、被検者情報表示領域601と、プローブ配置表示領域602と、波形表示領域603と、統計データ表示領域604と、コメント記載欄605と、参考情報表示領域606と、関係者等情報表示領域607と、を構成項目として含んでいる。
 図13に示されるように、被検者情報表示領域601においては、被検者の姓名を表示しないように設定変更されている。
In FIG. 13, a customized test result display 1300 includes, for example, a subject information display area 601, a probe placement display area 602, a waveform display area 603, a statistical data display area 604, a comment description column 605, The reference information display area 606 and the related person information display area 607 are included as configuration items.
As shown in FIG. 13, in the subject information display area 601, the setting is changed so as not to display the first and last names of the subject.
 プローブ配置表示領域602では、チャンネル10が領域1として設定され、領域1を示す印(1301)が表示され、チャンネル6が領域2として設定され、領域2を示す印(1302)が表示されている。ここでは、課題として注意課題(オドボール検査)が実施されているため、前頭前野及び頭頂葉に対する2つの領域が解析対象チャンネルとして設定されている。なお、プローブ配置表示領域602においては、脳表(MNI座標系もしくはTalairach座標系)でのチャンネル(測定位置)表示としてもよい。この場合、被検者の利き手情報に基づいて、表示する計測部位を左右で切り替えても良い。例えば、右利きの場合、右側部位を表示し、左利きの場合、左側部位を表示する。これにより、利き手により左右脳部位において異なる活動及び反応が期待される場合に、医師及びオペレータにとって有用な情報を効率的に表示できるという効果がある。 In the probe arrangement display area 602, the channel 10 is set as the area 1, the mark (1301) indicating the area 1 is displayed, the channel 6 is set as the area 2, and the mark (1302) indicating the area 2 is displayed. . Here, since an attention task (odd ball inspection) is performed as a task, two regions for the prefrontal cortex and parietal lobe are set as analysis target channels. In the probe arrangement display area 602, a channel (measurement position) display on the brain surface (MNI coordinate system or Talairach coordinate system) may be used. In this case, the measurement site to be displayed may be switched between left and right based on the dominant hand information of the subject. For example, when right-handed, the right part is displayed, and when left-handed, the left part is displayed. Thus, when different activities and reactions are expected in the left and right brain regions by the dominant hand, there is an effect that information useful for the doctor and the operator can be efficiently displayed.
 波形表示領域603では、ヘモグロビン変化の軸範囲が-0.10から0.10に設定され、領域1の差分平均値波形(酸素化ヘモグロビン濃度及び脱酸素化ヘモグロビン濃度の差分波形)が表示されている。ここでは差分波形を表示しているが、医師やオペレータの選択により、ベースライン期間、課題実行期間の平均値の比の値及び比の波形を表示しても良い。さらに、波形の時間的積分値、平均値、所定期間で算出された波形の重心値、波形における所定期間の傾き、所定波形(例えば,Hemodynamic response function: HRF)との相関値、等の情報を表示しても良い。 In the waveform display area 603, the axial range of hemoglobin change is set from −0.10 to 0.10, and the difference average value waveform (difference waveform of oxygenated hemoglobin concentration and deoxygenated hemoglobin concentration) in area 1 is displayed. Yes. Although the differential waveform is displayed here, the ratio value of the average value of the baseline period and the task execution period and the waveform of the ratio may be displayed by the selection of the doctor or the operator. Furthermore, information such as the temporal integration value of the waveform, the average value, the centroid value of the waveform calculated in a predetermined period, the slope of the waveform in a predetermined period, the correlation value with a predetermined waveform (for example, Hemodynamic response function: HRF), etc. You may display.
 統計データ表示領域604では、領域1及び2におけるベースライン期間、課題実行期間の平均値、及びそれらの差である差分平均値が表示されている。また、これらの値が図8で入力されたカットオフ値803以上である場合には、対応する値の背景色が変化するように表示される。ここでは、波形の時間的積分値、平均値、所定期間で算出された波形の重心値、波形における所定期間の傾き、所定波形(例えば,Hemodynamic response function: HRF)との相関値、等の情報を表示しても良い。 In the statistical data display area 604, the baseline period in the areas 1 and 2, the average value of the task execution period, and the difference average value that is the difference between them are displayed. If these values are equal to or higher than the cutoff value 803 input in FIG. 8, the corresponding values are displayed so that the background color changes. Here, information such as the temporal integration value of the waveform, the average value, the centroid value of the waveform calculated for a predetermined period, the slope of the waveform for a predetermined period, the correlation value with a predetermined waveform (for example, Hemodynamic response function: HRF), etc. May be displayed.
 参考情報表示領域606には、測定部107によって測定されたデータの測定日時が自動で入力される。そして、医師やオペレータは、測定日時に対応させて治療薬及びその投与量の情報や実行課題の情報を入力(選択入力)することができるようになっている。なお、参考情報として治療薬や実行課題の情報を入力すると、その入力に対応して解析対象チャンネルが自動的に登録されるようにしても良い。 In the reference information display area 606, the measurement date and time of the data measured by the measurement unit 107 is automatically input. A doctor or an operator can input (selective input) information on a therapeutic agent and its dose and information on an execution task in correspondence with the measurement date and time. Note that when information on a therapeutic drug or an execution task is input as reference information, the analysis target channel may be automatically registered in response to the input.
 <検査結果表示のレイアウト設定の変形例>
 図14は、本実施形態の変形例による、検査結果表示のレイアウト設定画面の構成例を示す図である。当該レイアウト設定画面1400は、レイアウト設定画面800と同様、例えば、図6の初期設定の画面で「レポート画面レイアウト」を押下するとポップアップ表示される。
<Modification of layout setting for inspection result display>
FIG. 14 is a diagram illustrating a configuration example of a layout setting screen for inspection result display according to a modification of the present embodiment. Similar to the layout setting screen 800, the layout setting screen 1400 is displayed as a pop-up when “report screen layout” is pressed on the initial setting screen of FIG.
 レイアウト設定画面1400は、レイアウト編集可能領域表示部1401_1及び1401_2と、表示内容設定部1402と、パラメータ設定部1403と、を構成項目として含んでいる。 The layout setting screen 1400 includes layout editable area display units 1401_1 and 1401_2, a display content setting unit 1402, and a parameter setting unit 1403 as configuration items.
 レイアウト編集可能領域表示部1401_1及び1401_2は、被検者情報表示領域から関係者等情報表示領域までの領域が画面上でどのようにレイアウトされるかを示している。図14の例では、被検者情報表示領域と関係者等情報表示領域について固定領域として表示内容を変更できないようになっており、その他の領域については任意の内容に設定可能になっている。また、「大」領域は、被検者情報表示領域の下に設けられる。「大」領域と関係者等情報表示領域の間に、画面1から画面10までの10個の領域が配置されるようになっている。 The layout editable area display sections 1401_1 and 1401_2 indicate how the area from the subject information display area to the information display area for related parties is laid out on the screen. In the example of FIG. 14, the display contents cannot be changed as fixed areas for the subject information display area and the related person information display area, and the other areas can be set to arbitrary contents. The “large” area is provided below the subject information display area. Ten areas from the screen 1 to the screen 10 are arranged between the “large” area and the information display area for related parties.
 内容表示設定部1402は、検査結果表示を構成する各領域において表示すべき内容を医師やオペレータが選択するためのツールである。医師やオペレータは、内容表示設定部1402を用いて、レポートの種類を入力すると共に、「大」領域、及び画面1乃至画面10の表示内容を入力することができる。図14では、プルダウンメニューによって入力内容を選択できるように構成されているが、医師等が直接入力できるようにしても良い。画面の種類としては、例えば、領域1波形(差分)、解析範囲の平均値表、コメント、計測実施日の参考情報、服用情報等の治療情報、特徴量マップ、評価スケール(例えば、Rating Scale)、領域2波形(差分)、領域1波形(オリジナル)、前記波形等の積分値、前記波形等の重心値、前記波形等の傾き、前記波形と他の所定の波形との相関値、等が挙げられる。図14では、コメント欄として2つ設定されているが、例えば、画面3に入力されたコメントは、診断補助情報400(図4参照)の診断結果416に自動的に反映され、画面8に入力されたコメントは、今後の治療に関する処置417に自動的に反映されるようにしても良い。 The content display setting unit 1402 is a tool for the doctor or operator to select the content to be displayed in each area constituting the test result display. A doctor or an operator can use the content display setting unit 1402 to input the type of report and input the “large” region and the display contents of the screens 1 to 10. In FIG. 14, the input content can be selected by a pull-down menu, but a doctor or the like may directly input. Examples of screen types include region 1 waveform (difference), analysis range average value table, comments, reference information on the date of measurement, treatment information such as medication information, feature map, evaluation scale (for example, Rating Scale) , Region 2 waveform (difference), region 1 waveform (original), integrated value of the waveform etc., centroid value of the waveform etc., inclination of the waveform etc., correlation value between the waveform and another predetermined waveform, etc. Can be mentioned. In FIG. 14, two comment fields are set. For example, a comment input to the screen 3 is automatically reflected in the diagnosis result 416 of the diagnosis auxiliary information 400 (see FIG. 4) and input to the screen 8. The comment that has been made may be automatically reflected in the treatment 417 regarding the future treatment.
 パラメータ設定部1403は、例えば、治療薬が被検者に効果があったか否かを示すための閾値や特徴量マップの横軸及び縦軸を設定するためのツールである。生体信号(平均値や差分平均値)の振幅値が閾値以上であれば治療薬が被検者に効果的であったことを意味し、閾値未満の場合には効果が小さかったことを意味する。このようにすることにより、検査結果報告表示おける統計データ表示領域604において、生体信号(平均値や差分平均値)が設定された閾値以上の場合にはその旨が分かるようなデータ表示形態(例えば、該当する欄の背景を赤く表示する)とすることが可能となる。 The parameter setting unit 1403 is, for example, a tool for setting a threshold value and a horizontal axis and a vertical axis of a feature amount map for indicating whether or not a therapeutic drug has an effect on a subject. If the amplitude value of the biological signal (average value or difference average value) is equal to or greater than the threshold value, it means that the therapeutic agent is effective for the subject, and if it is less than the threshold value, the effect is small. . By doing in this way, in the statistical data display area 604 in the test result report display, when the biological signal (average value or difference average value) is equal to or higher than the set threshold value, a data display form (for example, that can be understood) , The background of the corresponding column is displayed in red).

<Example of information displayed on each screen>
FIGS. 15 to 18 are diagrams for explaining examples of information that can be displayed on the layout editable area display units 1401_1 and 1401_2 of the layout setting screen 1400 of the inspection result display. Each information (tool) listed below is generated by the calculation unit 109 using information necessary for display.
(i)ADHD評価スケール(Rating Scale)
 図15は、検査結果表示の画面に表示することができる、ADHD評価スケールグラフ1501、及びADHD評価スケール表1502の表示例を示す図である。検査結果表示には両方を表示しても良いし、何れか一方であっても良い。
(I) ADHD rating scale (Rating Scale)
FIG. 15 is a diagram showing a display example of an ADHD evaluation scale graph 1501 and an ADHD evaluation scale table 1502 that can be displayed on the examination result display screen. Both may be displayed in the inspection result display, or either one may be displayed.
 ADHD評価スケールは、被検者の親や学校の担当教師(先生)が被検者を観察し、質問事項に主観的な観点で回答することにより得られるスコア値である。ADHD評価は、例えば不注意、多動・衝動、及びトータル(不注意及び多動・衝動を含めたトータルの行動)について行われる。このようにして得られるADHD評価スケールを被検者に関連付けてデータベース104に格納し、必要に応じて演算部109が取得しても良いし、入力部101から別途入力しても良い。 The ADHD evaluation scale is a score value obtained by observing the subject by the subject's parent or the teacher in charge of the school (teacher) and answering the question items from a subjective viewpoint. The ADHD evaluation is performed on, for example, carelessness, hyperactivity / impulse, and total (total behavior including carelessness, hyperactivity / impulse). The ADHD evaluation scale obtained in this way is stored in the database 104 in association with the subject, and may be acquired by the calculation unit 109 as necessary, or may be input separately from the input unit 101.
 B1(Base line 1)、S2(Stimulation 2)、S3(Stimulation 3)それぞれの記録は、次のような方法で行われる。例えば、B1計測時(計測前後の近い日)にRating Scale(1回目)を実施し、それを表の「B1」項目に記録する。また、S2計測時(前後の近い日)にRating Scale(2回目)を実施し、それを表の「S2」項目に記録する。さらに、S3計測時(前後の近い日)にRating Scale(3回目)を実施し、それを表の「S3」項目に記録する。 Recording of each of B1 (Base line 1), S2 (Stimulation 2), and S3 (Stimulation 3) is performed by the following method. For example, Rating Scale (first time) is performed at the time of B1 measurement (the days before and after the measurement), and this is recorded in the “B1” item of the table. Also, Rating Scale (second time) is performed at the time of S2 measurement (the days before and after), and is recorded in the “S2” item of the table. Further, Rating Scaling (third time) is performed at the time of S3 measurement (the days before and after), and is recorded in the “S3” item of the table.
 その他の画面領域には前述のように脳機能計測信号(生体信号の平均値等)が表示されるため、このような生体信号と評価スケール(例えば、Rating Scale)の時系列情報とを同時に表示することにより、医師の病状等に関する総合的判断を補助することができる。 Since the brain function measurement signals (average values of biological signals, etc.) are displayed in the other screen areas as described above, such biological signals and time series information of the evaluation scale (eg Rating Scale) are displayed simultaneously. By doing so, it is possible to assist a doctor's comprehensive judgment regarding medical conditions and the like.
(ii)特徴量マップ
 図16は、検査結果表示の画面に表示することができる特徴量マップ1600の表示例を示す図である。
(Ii) Feature Quantity Map FIG. 16 is a diagram showing a display example of a feature quantity map 1600 that can be displayed on the examination result display screen.
 ADHD検査(go / no-go(抑制課題:Inhibition task)・オドボール(注意課題:Attention task))においては、Rating Scale図・表(図15)の他、Rating Scaleと計測した光トポグラフィ計測における平均値との関連を散布図で表示する特徴量マップを表示する場合がある。この特徴量マップ1600は、主観的な評価スコア値(Rating Scale)と客観的な生体信号(解析区間におけるヘモグロビン濃度の測定値の平均値)との相関性を判断するためのツールである。ここでは評価スコア値と解析区間におけるヘモグロビン濃度の測定値の平均値の相関を示す特徴量マップを生成しているが、客観的指標としては他の値、例えば、生体信号のピーク値、分散値、積分値、重心値、傾き、相関値等に設定してもよい。 In ADHD inspection (go / no-go (inhibition task: Inhibition task) and oddball (attention task)), in addition to Rating Scale charts and tables (Figure 15), the average of optical topography measurements with RatingRScale There is a case in which a feature amount map that displays a relation with a value in a scatter diagram is displayed. This feature map 1600 is a tool for determining the correlation between a subjective evaluation score value (Rating Scale) and an objective biological signal (the average value of hemoglobin concentration measurement values in the analysis section). Here, a feature amount map is generated that shows the correlation between the evaluation score value and the average value of the measured values of hemoglobin concentration in the analysis interval, but other values such as the peak value of the biological signal and the variance value are used as objective indicators. , Integral value, centroid value, slope, correlation value, etc.
 このような特徴量マップ1600を提示することにより、評価スケールのスコア値と生体信号との比較を容易に行うことができ、評価者(医師やオペレータ)は両者の相関関係を把握しやすくなる。 By presenting such a feature amount map 1600, it is possible to easily compare the score value of the evaluation scale with the biological signal, and the evaluator (doctor or operator) can easily grasp the correlation between the two.
(iii)レーダチャート
 図17は、検査結果表示の画面に表示することができるレーダチャート1700の表示例を示す図である。図17においては、治療薬を服用し、与えられた課題を実施すると共に評価者(親や医師)によるRating Scale(スコア評価)を行うことを1セットとして、これを3回繰り返した場合の検査結果が示されている。
(Iii) Radar Chart FIG. 17 is a diagram showing a display example of a radar chart 1700 that can be displayed on the inspection result display screen. In FIG. 17, taking a therapeutic drug, performing a given task, and performing a rating scale (score evaluation) by an evaluator (parent or doctor) as a set, this test is repeated three times. Results are shown.
 レーダチャート1700は、薬効に関連する複数のパラメータを表示し、現在使用している治療薬が被検者にとって効果があるか否かについての評価者の判断を補助するためのツールである。レーダチャート1700においては、例えば、チャートの外側に行くほど改善したことを示すように軸が配置される。なお、各計測回に対応する多角形の面積を指標とし表示することも可能である。 The radar chart 1700 is a tool for displaying a plurality of parameters related to drug efficacy and assisting the evaluator in determining whether the currently used therapeutic drug is effective for the subject. In the radar chart 1700, for example, an axis is arranged so as to indicate that the improvement is made toward the outside of the chart. It is also possible to display the area of the polygon corresponding to each measurement time as an index.
 レーダチャート1700において表示されるパラメータとしては、例えば、へモグロビン変化信号差分値(治療薬服用前後の差分)1701と、ブロック間の相関係数1702と、反応時間の逆数1703、正答率1704と、Rating Scale(逆数)1705を挙げることができる。もちろんこれ以外のパラメータを含めても良い。 The parameters displayed in the radar chart 1700 include, for example, a hemoglobin change signal difference value (difference before and after taking a therapeutic drug) 1701, a correlation coefficient 1702 between blocks, an inverse number 1703 of a reaction time, a correct answer rate 1704, Rating Scale (reciprocal) 1705 can be mentioned. Of course, other parameters may be included.
 へモグロビン変化信号差分値1701は、治療薬服用前に測定したヘモグロビン濃度値(生体信号)と治療薬服用前に測定したヘモグロビン濃度値(生体信号)との差分値を示しており、差分値が大きいほど改善が見られたことを意味している。 The hemoglobin change signal difference value 1701 indicates the difference value between the hemoglobin concentration value (biological signal) measured before taking the therapeutic drug and the hemoglobin concentration value (biological signal) measured before taking the therapeutic drug. The larger the value, the better.
 ブロック間の相関係数1702は、1回の検査の際には被検者が複数回の課題を実施する(例えば、同じ課題(注意課題)を6回実施する)が、各回を1ブロックとしたときに各ブロック間に相関があるか否かを示す情報である。各ブロックにおいて類似した生体信号の波形が測定されれば相関が高いと判定され、非類似であると相関は小さくなる。薬効があった場合には相関はより高くなる。なお、相関の値は、一例として、生体信号を時間軸上で比較して差分をとり、当該差分の2乗の総和を算出することによって求めることができる。または、6回分の測定波形の任意の2回分の波形間の相関係数を、取り得る全組み合わせで算出し、平均化したものを相関の値としても良い。 The correlation coefficient 1702 between blocks is that a subject performs a plurality of tasks in one examination (for example, the same task (attention task) is performed six times), but each time is regarded as one block. This is information indicating whether or not there is a correlation between each block. If a waveform of a similar biological signal is measured in each block, it is determined that the correlation is high, and if it is dissimilar, the correlation is small. The correlation is higher when there is a medicinal effect. For example, the correlation value can be obtained by comparing the biological signals on the time axis to obtain a difference and calculating the sum of the squares of the difference. Alternatively, correlation coefficients between arbitrary two waveforms of six measured waveforms may be calculated in all possible combinations and averaged may be used as the correlation value.
 反応時間の逆数1703は、被検者が課題を実行した場合に得られる反応時間の逆数を取った値である。反応時間は小さいほど課題に対して好成績と判断されるため、ここでは逆数を取ることにしている。
 正答率1704は、被検者が課題を実行した場合に得られる正答率の値である。正答率は高い方が好成績と判断される。
The reciprocal 1703 of the reaction time is a value obtained by taking the reciprocal of the reaction time obtained when the subject executes the task. The smaller the reaction time is, the better the result is for the task, so the reciprocal is taken here.
The correct answer rate 1704 is a value of the correct answer rate obtained when the subject executes the task. The higher the correct answer rate, the better.
 Rating Scale(逆数)1705は、評価者(医師やオペレータ)による主観的な評価のスコア値の逆数を取った値である。スコア値は高いほどADHDの傾向が強い(症状改善が見られない)ことを意味し、小さいほど症状改善が見られることを意味するため、逆数を取ることにしている。 Rating Scale (reciprocal) 1705 is a value obtained by taking the reciprocal of the score value of subjective evaluation by the evaluator (doctor or operator). The higher the score value, the stronger the tendency of ADHD (the symptom improvement is not seen), and the smaller the value, the more the symptom improvement is seen. Therefore, the reciprocal is taken.
 このようなレーダチャート1700を提示することにより、各回の検査時における被検者の状態を容易に把握でき、医師やオペレータに総合的な薬効判断を促すことができる。 By presenting such a radar chart 1700, it is possible to easily grasp the condition of the subject at the time of each examination, and to prompt a doctor or operator to make a comprehensive medicinal effect determination.
(iv)課題正答率の変化と平均反応時間との関係
 図18は、被検者が課題を実行した際に得られた課題正答率の変化(増加)と課題を回答する際に費やした反応時間との関係(例)を示す図(グラフ)である。
(Iv) Relationship between change in task correct answer rate and average reaction time FIG. 18 shows changes (increase) in task correct answer rate obtained when the subject executed the task and the response spent in answering the task. It is a figure (graph) which shows the relationship (example) with time.
 図18のグラフでは、検査を重ねることにより、課題正答率は増加し、平均反応時間が短くなっている。従って、このグラフから治療薬による改善が見られる場合には、正答率が増加すると共に平均反応時間が短くなることが分かるようになる。 In the graph of FIG. 18, by repeating examinations, the correct answer rate increases and the average reaction time decreases. Therefore, it can be seen from this graph that when the improvement by the therapeutic agent is seen, the correct response rate increases and the average reaction time decreases.
 このように、複数回の測定における課題正答率の増加及び平均反応時間を表示することにより、行動評価から治療効果を可視化することができる、また、これらを治療情報と同時に表示することにより、さらに効果的な情報提示を実現することができる。 Thus, by displaying the increase in the correct answer rate and average response time in multiple measurements, it is possible to visualize the treatment effect from the behavioral evaluation, and by displaying these simultaneously with the treatment information, Effective information presentation can be realized.
 <まとめ>
(i)本開示の実施形態において、脳機能指標出力装置(診断補助システム)は、データベースから被検体(被検者)に関する情報(ID、姓名、利き手、生年月日等)と、被検体に対する治療情報(治療薬とその投与量、投与日時等)を取得する。また、脳機能指標出力装置は、測定部によって測定された被検者の被検体の所定の部位(脳)における生体信号(脳の血管中のヘモグロビン濃度変化を示す光トポグラフィデータ)を取得する。そして、脳機能指標出力装置は、被検体に関する情報と、治療情報と、生体信号と、を統合して統合情報(診断補助情報)を生成し、当該統合情報に含まれる複数種類の情報を検査結果表示として表示装置の画面に同時に表示するための表示処理を実行する。このように、生体信号と被検者の治療情報を並列表示して提示することにより、医師やオペレータはわざわざ治療情報を別途取得して表示された生体信号と突き合わせる必要がなくなり、投薬などの治療による症状改善効果をより効果的に、定量的に評価することが可能となる。また、これにより、総合的な診断を補助することができるようになる。
<Summary>
(I) In the embodiment of the present disclosure, the brain function index output device (diagnosis auxiliary system) includes information (ID, first name, dominant hand, date of birth, etc.) on the subject (subject) from the database, Acquire treatment information (therapeutic drug and its dose, administration date, etc.). The brain function index output device also acquires a biological signal (optical topography data indicating a change in hemoglobin concentration in the blood vessels of the brain) in a predetermined part (brain) of the subject of the subject measured by the measurement unit. The brain function index output device generates integrated information (diagnosis auxiliary information) by integrating information on the subject, treatment information, and biological signals, and examines a plurality of types of information included in the integrated information. A display process for simultaneously displaying the result on the screen of the display device is executed. In this way, by displaying the biological signal and the treatment information of the subject in parallel, doctors and operators do not have to bother to acquire the treatment information separately and match the displayed biological signal. It becomes possible to evaluate the symptom improvement effect by treatment more effectively and quantitatively. In addition, this makes it possible to assist comprehensive diagnosis.
 脳機能指標出力装置は、さらに、課題部から所定の課題(注意課題や抑制課題)に対する被検体の実行結果(反応時間や課題の正答率)を取得し、当該実行結果を統合情報(診断補助情報)に含めて検査結果表示を生成する。このように課題に対する被検者の反応を表示情報として含めることにより、投薬などの治療による症状改善効果をより客観的に評価することができるようになる。 The brain function index output device further obtains the execution result (reaction time and correct answer rate) of the subject with respect to a predetermined task (attention task or suppression task) from the task unit, and integrates the execution result with the integrated information (diagnosis assistance) Information) to generate a test result display. By including the subject's reaction to the task as display information in this way, the symptom improvement effect by treatment such as medication can be more objectively evaluated.
 被検者の過去の検査結果がある場合、過去の検査において取得された生体信号と過去の課題の実行結果とを取得し、当該過去の生体信号及び課題の実行結果を統合情報に含めてもよい。これにより、過去と現在のデータを容易に比較することができるようになる。また、今回の検査において取得された課題の実行結果と、過去の検査において取得された課題の実行結果との比較を可能とする情報を生成して検査結果表示(図18)に含めても良い。さらに、被検者の過去の検査において取得された生体信号と過去の課題の実行結果とを取得すると共に、今回の検査及び過去の検査時における被検者に対する行動観察の評価結果の入力を受け付け、今回の検査において取得された生体信号及び過去の検査において取得された生体信号と、今回及び過去の検査時における評価結果との相関を示す情報(図16)を生成し、検査結果表示に含めてもよい。このように様々な情報を提供することにより、より客観的で効果的な診断ができるように補助することが可能となる。 If there are past test results of the subject, the biometric signal acquired in the past test and the execution result of the past task may be acquired, and the past biosignal and the execution result of the task may be included in the integrated information Good. This makes it possible to easily compare past and present data. Further, information that enables comparison between the execution result of the task acquired in the current examination and the execution result of the task acquired in the past examination may be generated and included in the examination result display (FIG. 18). . Furthermore, the biosignal acquired in the past examination of the subject and the execution result of the past task are obtained, and the input of the evaluation result of the behavior observation for the subject during the current examination and the past examination is accepted. The information (FIG. 16) indicating the correlation between the biological signal acquired in the current examination and the biological signal acquired in the previous examination and the evaluation result in the current examination and the past examination is generated and included in the examination result display. May be. By providing various information in this way, it is possible to assist so that a more objective and effective diagnosis can be performed.
 検査結果表示を生成する際には、医師やオペレータは、表示レイアウト及び表示内容について指示することができる。このように、カスタマイズされた検査結果表示を生成することにより、医師等にとって診断しやすい表示形態で情報を提供することができるようなる。 When generating a test result display, a doctor or an operator can instruct the display layout and display contents. In this manner, by generating a customized test result display, information can be provided in a display form that is easy for a doctor or the like to diagnose.
 また、生体信号を提供する場合には、測定データそのものを提供するのではなく、生体信号を統計処理(平均や差分平均を算出)して生成した統計データを提供する。生データを提供した場合にはデータのばらつきが誤診につながる可能性があるが、統計処理することにより、医師等による、より妥当な診断を促すことが可能となる。 Also, when providing a biological signal, the measurement data itself is not provided, but statistical data generated by statistical processing (calculating an average or difference average) of the biological signal is provided. When raw data is provided, data variation may lead to misdiagnosis, but statistical processing can encourage more appropriate diagnosis by a doctor or the like.
 検査結果表示において、統計データを数値表示する場合には、医師等により設定入力された閾値に基づいて統計データの表示形態を変化させるようにしても良い。これにより、治療効果があったか否か容易に判断することができるようになる。 In the test result display, when the statistical data is displayed numerically, the display form of the statistical data may be changed based on a threshold value set and inputted by a doctor or the like. Thereby, it becomes possible to easily determine whether or not there is a therapeutic effect.
 従来、医師やオペレータは、被検者が実行する課題や服用する治療薬の種類に応じて、脳のどの部位から生体信号を取得するか決定しなければならなかったが、本実施形態では、課題や治療薬の種類に応じて自動的に脳の部位を選択して解析対象チャンネル(領域)を設定し、そのチャンネルから生体信号を取得するようにしても良い。このようにすることにより、課題や治療薬の種類に応じて適切な部位の生体信号を確実に取得することができる。よって、経験が比較的浅い医師等にとっても効果的な診断補助を提供することが可能となる。 Conventionally, doctors and operators had to determine from which part of the brain to obtain a biological signal, depending on the subject executed by the subject and the type of therapeutic drug to be taken, in this embodiment, A brain region may be automatically selected according to the problem and the type of therapeutic agent, an analysis target channel (region) may be set, and a biological signal may be acquired from the channel. By doing in this way, the biological signal of an appropriate site | part can be acquired reliably according to a subject and the kind of therapeutic agent. Therefore, it is possible to provide effective diagnosis assistance even for doctors who have relatively little experience.
