Abstract

<P>PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device capable of easily correcting and determining an accurate gestational age regardless of the time of a medical examination by providing a means for plotting a measured result on a graph and then moving and displaying the gestational age at a plot position. <P>SOLUTION: A horizontal axis displays the gestational age, a vertical axis displays a measured value, the statistical average of CRL, the upper limit of a statistical deviation and the lower limit of the statistical deviation, and a measured CRL is plotted at the position of the gestational age calculated from an LMP. In the case that it is recognized from the graph that there is a slight deviation, the plot position is moved and matched with the statistical average of the CRL, and the gestational age recorded in a patient attribute part is overwritten and corrected. Further, by simultaneously displaying the statistical average and deviation graph of the CRL and a BPD and moving the gestational age so as to minimize the difference, the correction of a further accurate gestational age is easily performed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、産婦人科での妊婦の検査又は診断(以下、「検診」という)に適用される超音波診断装置、または胎児の出産日決定装置に関する。   The present invention relates to an ultrasonic diagnostic apparatus or a fetal birth date determination apparatus applied to examination or diagnosis (hereinafter referred to as “examination”) of a pregnant woman in obstetrics and gynecology.

従来の超音波診断装置は、図8に示すように胎児の指定の部位(図8の例では、胎児頭臀長(Crown-Rump Length以下、CRL)を計測し、CRLの値と、CRLの値から推定した妊娠周数(GA)の値を画面に表示する(例えば特許文献1参照)。妊娠周数(GA)、あるいはそこから決まる出産予定日は、まずは、最終月経日(Last Menstrual Period、以下、LMP)から推定されるが、LMPは、しばしば、記憶があいまいであって正確でないことや、忘れられていることがある。従って、出産予定日の精度を上げるために妊娠周数(GA)の修正は、前記CRLから推定したGA(例えば 62day)と、最終月経日(LMP)から推定したGA(例えば 63day)の数値比較から行っている。   As shown in FIG. 8, the conventional ultrasonic diagnostic apparatus measures the fetal designated part (in the example of FIG. 8, the fetal head length (hereinafter referred to as CRL)), the CRL value, and the CRL value. The value of the pregnancy frequency (GA) estimated from the value is displayed on the screen (see, for example, Patent Document 1.) The pregnancy frequency (GA) or the expected delivery date determined from the first is the last menstrual period The LMP is often ambiguous and inaccurate or has been forgotten, so the pregnancy frequency (in order to improve the accuracy of the expected date of birth) The correction of GA is performed by comparing numerical values of GA estimated from the CRL (for example, 62 days) and GA estimated from the last menstrual day (LMP) (for example, 63 days).

また、図9に示すように、グラフを用いて、CRLから推定したGA(例えば 62day)と、最終月経日(LMP)から推定したGA(例えば 63day)を視覚的に比較し、妊娠周数の修正を行っている。

以上のように構成された超音波診断装置について、図3、図4を用いてその動作を説明する。   The operation of the ultrasonic diagnostic apparatus configured as described above will be described with reference to FIGS.

まず、検査または診断(以下、検診と略す)を始めるときには、操作卓12より患者IDを入力し、また、このときLMPが分かれば操作卓12よりLMPを入力する。図3の例の場合では、LMPから計算した妊娠周数は、11週3日(図3の表示「11w3d」:以下同様)であったとする。入力した患者IDは、患者データ用メモリ15の患者F10の患者ID部21に、LMPとLMPから計算した妊娠周数は、患者データ用メモリ15の患者属性部22に記録される。超音波プローブ1を被検体(ここでは妊婦)にあて、超音波を送受信し、受信信号処理回路部4、DSC5,画像合成部6を通して、超音波画像がTVモニタ7に表示される。   First, when starting examination or diagnosis (hereinafter abbreviated as “examination”), the patient ID is input from the console 12. If the LMP is known at this time, the LMP is input from the console 12. In the case of the example in FIG. 3, it is assumed that the pregnancy frequency calculated from the LMP is 11 days and 3 days a week (display “11w3d” in FIG. 3: the same applies hereinafter). The entered patient ID is recorded in the patient ID section 21 of the patient F10 in the patient data memory 15, and the pregnancy frequency calculated from the LMP and LMP is recorded in the patient attribute section 22 of the patient data memory 15. The ultrasonic probe 1 is applied to a subject (here, a pregnant woman), ultrasonic waves are transmitted and received, and an ultrasonic image is displayed on the TV monitor 7 through the reception signal processing circuit unit 4, the DSC 5, and the image synthesis unit 6.

測定したい部位が描出できたら、操作卓12で、画像をフリーズさせる。フリーズした画像に計測したい部位を表示できていれば、操作卓12で計測キーを押して、計測を開始する。例えば、測定したい部位として胎児の頭臀長(以下、CRL)を計測する場合には、操作卓12で、TVモニタ7に表示される計測用カーソルを移動し、計測の始点と終点を決定する。   When the part to be measured is drawn, the console 12 freezes the image. If the part to be measured can be displayed on the frozen image, the measurement key is pressed on the console 12 to start measurement. For example, when measuring the length of the head of the fetus (hereinafter referred to as CRL) as a region to be measured, the measurement cursor displayed on the TV monitor 7 is moved on the console 12 to determine the measurement start and end points. .

この例では、41mmであったとする(図3の例の場合は、(11週3日、41mm)の位置55)。ここまでの計測の一連の操作は、中央制御回路11が制御し、計測用カーソルの表示は、グラフィックス制御回路13、グラフィックスメモリ回路14、画像合成部6を介して、TVモニタ7に表示される。   In this example, it is assumed that the distance is 41 mm (in the case of the example in FIG. 3, the position 55 at (11 weeks 3 days, 41 mm)). A series of measurement operations so far are controlled by the central control circuit 11, and a measurement cursor is displayed on the TV monitor 7 via the graphics control circuit 13, the graphics memory circuit 14, and the image composition unit 6. Is done.

さらに、操作卓12で、CRLを計測した旨を決定するためのキーを押すと、中央制御回路部11は、CRLの計測結果を患者データ用メモリ15の患者F10の計測データ部23の診察日1のエリアに、検診の日付とともに記録する。   Further, when a key for determining that CRL is measured is pressed on the console 12, the central control circuit unit 11 displays the CRL measurement result on the examination date of the measurement data unit 23 of the patient F10 in the patient data memory 15. Record in 1 area with date of screening.

ここで、操作卓12で、胎児の発育度合いを示すグラフ(以下、成長曲線)を表示する旨のボタン(不図示)を押す。ボタンは中央制御回路部11によって認識され、グラフィックス制御回路13、グラフィックスメモリ回路14、画像合成部6を介して、TVモニタ7に図3のようにグラフ表示される。このときグラフは、横軸50が妊娠周数、縦軸51が計測値となっている。また、CRLの統計的平均値52、統計的偏差の上限53、統計的偏差の下限54を同時に表示する。計測したCRLは、LMPから計算された周数(図3の例の場合は、11週3日、41mm)の位置55にプロットされる。   Here, on the console 12, a button (not shown) for displaying a graph indicating the degree of fetal growth (hereinafter, growth curve) is pressed. The button is recognized by the central control circuit unit 11 and displayed on the TV monitor 7 as a graph as shown in FIG. 3 via the graphics control circuit 13, the graphics memory circuit 14, and the image composition unit 6. In this graph, the horizontal axis 50 is the pregnancy frequency and the vertical axis 51 is the measured value. The CRL statistical average value 52, the statistical deviation upper limit 53, and the statistical deviation lower limit 54 are simultaneously displayed. The measured CRL is plotted at the position 55 of the frequency calculated from the LMP (in the case of FIG. 3, 11 weeks, 3 days, 41 mm).

この例の場合、CRLの統計的平均値52は、11週1日までしか得られていないが、41mmという検診による計測結果は、CRLの統計的平均値からは、わずかにずれがあることがグラフからわかる。操作者である医者は、ここで、LMPが確かなものか患者に確認するが、患者の記憶が正確でないと申告された場合、操作卓12の操作で、プロット位置55を図4に示すプロット位置56の位置まで移動する。移動した結果、CRLの統計的平均と一致する事ができ、そのときの妊娠周数の修正した値が、11週1日であることがわかる。   In this example, the CRL statistical average value 52 is obtained only up to 1st day of 11 weeks, but the measurement result by the screening of 41 mm may slightly deviate from the CRL statistical average value. You can see from the graph. Here, the doctor who is the operator confirms with the patient whether the LMP is reliable, but if the patient's memory is declared inaccurate, the plot position 55 shown in FIG. Move to position 56. As a result of the movement, it is possible to agree with the statistical average of the CRL, and it is understood that the corrected value of the pregnancy frequency at that time is 1 day of 11 weeks.

医者は、ここで、操作卓12で、修正した妊娠周数を記憶する旨のキーを押して、患者データ用メモリ15の患者F10の患者属性部22に記録した妊娠周数を上書きして修正、記録する。これら一連の動作は、中央制御回路11によってコントロールされる。   Here, the doctor presses the key for storing the corrected pregnancy frequency on the console 12 and overwrites and corrects the pregnancy frequency recorded in the patient attribute section 22 of the patient F10 in the patient data memory 15. Record. These series of operations are controlled by the central control circuit 11.

このような本発明の第1の実施の形態の超音波診断装置によれば、妊娠周数を上書きして修正、記録する一連の動作をコントロールできる中央制御回路11と中央制御回路11を含む制御系回路部10を設けることにより、LMPから求めた妊娠周数が、任意部位の統計的平均値が得られている有効周数からわずかに範囲外の場合でも、その統計的平均値のグラフを見ながら、より正確な妊娠周数を容易に修正することができる。また、推定または修正し決定した新たな妊娠周数を記録することができる。   According to the ultrasonic diagnostic apparatus of the first embodiment of the present invention, the control including the central control circuit 11 and the central control circuit 11 that can control a series of operations for overwriting and correcting and recording the pregnancy frequency. By providing the system circuit section 10, even if the pregnancy frequency obtained from the LMP is slightly outside the effective frequency range where the statistical average value of an arbitrary part is obtained, a graph of the statistical average value is obtained. While looking, it is possible to easily correct a more accurate pregnancy frequency. It is also possible to record a new pregnancy frequency determined by estimation or correction.

以上のように、計測結果をグラフ上にプロットした後、プロット位置の周数を移動させ、表示する手段を設けることにより、検診を行う期間によらず、正確な妊娠周数を容易に修正し決定することができるという効果を有する。
なお、計測結果をグラフ上にプロットした後、プロット位置の周数を移動させて表示するにあたり、前後のプロットの区別がつくように表示するグラフの要素の色、形状、あるいは輝度等を変えて重畳して表示してもよい。
As described above, after plotting the measurement results on the graph, the exact pregnancy frequency can be easily corrected regardless of the screening period by providing a means to move and display the frequency at the plot position. It has the effect that it can be determined.
In addition, after plotting the measurement results on the graph, when changing the frequency of the plot position and displaying it, change the color, shape, brightness, etc. of the graph elements so that the plots before and after can be distinguished You may superimpose and display.

次に、本発明の第2の実施の形態の超音波診断装置について、図5、図6を用いてその動作を説明する。最初の検診で患者からLMPを確認し、妊娠周数を10週2日と決定する。操作卓12で、患者IDとLMPを入力し、それぞれ患者データ用メモリ15の患者F11の患者ID部21、患者属性部22に記録、検診の日付も患者属性部22に記録する。次に、超音波画像でCRLを表示させ、操作卓12で計測を行う。計測結果は32mmだったとすると、それは患者データ用メモリ15の患者F11の計測データ部23の診察日1のエリアに記録される。また、操作卓12で、成長曲線を表示する旨のボタンを押すと、図5の57の位置にプロット、表示される。(この段階では、図5の63、64は、まだプロットされていない。)この段階で、計測結果は、CRLの統計的平均値52のグラフと一致していないことが分かるが、ここでは、妊娠周数の修正は行わずに、単に計測結果を記録するだけにしておく。   Next, the operation of the ultrasonic diagnostic apparatus according to the second embodiment of the present invention will be described with reference to FIGS. LMP is confirmed from the patient at the first screening, and the pregnancy frequency is determined to be 10 weeks and 2 days. The patient ID and LMP are input on the console 12 and recorded in the patient ID part 21 and the patient attribute part 22 of the patient F11 of the patient data memory 15, respectively, and the examination date is also recorded in the patient attribute part 22. Next, the CRL is displayed as an ultrasonic image, and measurement is performed on the console 12. If the measurement result is 32 mm, it is recorded in the area of the examination date 1 of the measurement data section 23 of the patient F11 in the patient data memory 15. Further, when a button for displaying a growth curve is pressed on the console 12, a plot is displayed at the position 57 in FIG. (At this stage, 63 and 64 in FIG. 5 are not yet plotted.) At this stage, it can be seen that the measurement results do not agree with the graph of the statistical average value 52 of the CRL. Just record the measurement result without correcting the pregnancy frequency.

その後、1週間+2日後の妊娠周数では11週4日に当たる日に上述と同じ患者さんが検診に来たとする。操作卓12で患者IDを入力すると、前回検診時のデータを患者データ用メモリ15の患者F11の患者ID部21で、患者IDが一致することで検索し、患者F11の患者属性部22から前回検診時の妊娠周数を読み出す。読み出した妊娠周数は、10週2日となっているが、今日は、それから1週間と2日経過しているので、今日の妊娠周数は、11週4日であることが計算でき、患者属性部22に新たに計算した妊娠周数と検診の日付が記録される。ここで超音波画像でBPDを表示させる。操作卓12で、BPDの計測を行い、計測結果が19mmであったとするとその旨が検診の日付とともに、患者データ用メモリ15の患者F11の計測データ部23の診察日2のエリアに記録される。この日の検診でも妊娠周数の修正は行わずに、これで検診を終了する。   Thereafter, it is assumed that the same patient as described above comes to the examination on the day corresponding to the 4th week of the 11th week in the gestational frequency after 1 week + 2 days. When the patient ID is entered on the console 12, the previous examination data is searched in the patient ID part 21 of the patient F11 in the patient data memory 15 by matching the patient ID, and the previous data is retrieved from the patient attribute part 22 of the patient F11. Read the number of pregnancy laps at the time of screening. The read pregnancy lap is 10 days and 2 days, but since today, 1 week and 2 days have passed since then, it can be calculated that today's pregnancy lap is 11 days and 4 days, The newly calculated pregnancy frequency and examination date are recorded in the patient attribute section 22. Here, the BPD is displayed as an ultrasonic image. If the BPD is measured on the console 12 and the measurement result is 19 mm, this is recorded in the area of the examination date 2 of the measurement data section 23 of the patient F11 in the patient data memory 15 together with the examination date. . The screening is completed without correcting the pregnancy frequency even during the screening on this day.

さらに3週間+5日後の妊娠周数では15週と2日に当たる日に検診を行ったとする。前回検診時と同様にデータが患者データ用メモリ15の患者F11から読み出され、今日の妊娠周数15週2日が、患者属性部22に検診の日付とともに記録される。超音波画像でBPDを表示させる。操作卓12で、BPDの計測を行い、計測結果が29mmであったとすると、その旨は、検診の日付とともに、患者データ用メモリ15の患者F11の計測データ部23の診察日3のエリアに記録される。   Further, it is assumed that the examination is performed on the days corresponding to the 15th week and the 2nd day in the gestational frequency after 3 weeks + 5 days. Data is read from the patient F11 in the patient data memory 15 as in the previous examination, and today's pregnancy frequency of 15 weeks and 2 days is recorded in the patient attribute section 22 together with the examination date. BPD is displayed with an ultrasonic image. If BPD is measured on the console 12 and the measurement result is 29 mm, this is recorded in the area of the examination date 3 of the measurement data section 23 of the patient F11 in the patient data memory 15 together with the examination date. Is done.

操作卓12で成長曲線を表示する旨のボタンを押すと、患者データ用メモリ15の患者F11の計測データ部23の診察日1のエリアから読み出されたCRLの計測結果が、プロット位置57にプロットされ、患者データ用メモリ15の患者F11の計測データ部23の診察日2のエリアから読み出されたBPDの計測結果がプロット位置63にプロットされ、今日の検診の結果のBPDは、プロット位置64にプロット、表示される。プロット位置57、63をプロットするときの妊娠周数は、今日の妊娠周数と、それぞれ診察日1、診察日2のエリアに記録されている過去の検診の日付から計算して決められる。ここで、操作卓12の操作でグラフ表示する妊娠周数を移動する旨の操作を行い、図5のプロット位置57、63、64が、図6のプロット位置58、65、66に移動して表示される。再度、操作卓12の操作でグラフ表示する妊娠周数を先と逆の方向に移動する旨の操作を行い、移動を繰り返し行うこともできる。移動前後のプロット位置を見比べることで、図6のプロット位置のほうが、過去の3回の計測結果と統計的平均の値の差が少ない事が確認できる。ここで、操作卓12で、修正した妊娠周数を記憶する旨のキーを押して、患者データ用メモリ15の患者F11の患者属性部22に妊娠周数を上書きして修正、記録する。これら一連の動作は、中央制御回路11によってコントロールされる。   When the button for displaying the growth curve is pressed on the console 12, the CRL measurement result read from the area of the examination date 1 in the measurement data section 23 of the patient F11 in the patient data memory 15 is displayed at the plot position 57. The BPD measurement result that is plotted and read from the area of the examination date 2 of the measurement data section 23 of the patient F11 in the patient data memory 15 is plotted at the plot position 63, and the BPD as a result of today's examination is the plot position. 64 is plotted and displayed. The gestational frequency when plotting the plot positions 57 and 63 is determined by calculating from the gestational frequency of today and the dates of past medical examinations recorded in the areas of the medical examination date 1 and the medical examination date 2 respectively. Here, the operation of moving the pregnancy frequency displayed in the graph by the operation of the console 12 is performed, and the plot positions 57, 63, 64 in FIG. 5 are moved to the plot positions 58, 65, 66 in FIG. Is displayed. It is also possible to repeat the movement by performing an operation to move the pregnancy frequency displayed in the graph in the opposite direction to the previous one by operating the console 12 again. By comparing the plot positions before and after the movement, it can be confirmed that the plot position in FIG. 6 has a smaller difference between the past three measurement results and the statistical average value. Here, a key for storing the corrected pregnancy frequency is pressed on the console 12 to overwrite and correct the pregnancy frequency in the patient attribute section 22 of the patient F11 of the patient data memory 15. These series of operations are controlled by the central control circuit 11.

以上のように本発明の第2の実施の形態の超音波診断装置によれば、過去の3回の計測結果及びCRLとBPDという2つの部位について1つのグラフ上に表示させ、操作卓12の操作でグラフ表示する妊娠周数を移動する旨の操作をコントロールする中央制御回路11と中央制御回路11含む制御系回路部10を設けることにより、過去に決定した妊娠周数や、検診開始時に決定した妊娠周数と、今回の検診の複数の計測結果から求めた妊娠周数に相違があった場合に、その複数部位の統計的平均値のグラフを見ながら、3つ以上の妊娠周数の間の最適な妊娠周数を求めることができ、より正確な妊娠周数を容易に決定することができる。   As described above, according to the ultrasonic diagnostic apparatus of the second embodiment of the present invention, the past three measurement results and the two parts CRL and BPD are displayed on one graph, and the console 12 By providing the central control circuit 11 for controlling the operation to move the pregnancy frequency displayed in the graph by the operation and the control system circuit unit 10 including the central control circuit 11, the pregnancy frequency determined in the past or determined at the start of the examination If there is a difference between the number of pregnancy laps and the number of gestation laps obtained from the results of multiple measurements of this screening, the number of gestation laps of three or more An optimal pregnancy frequency can be obtained during this period, and a more accurate pregnancy frequency can be easily determined.

また、過去の検診結果と今回の検診結果を考慮して、より正確な妊娠周数の修正を容易に行う事ができる。   In addition, it is possible to easily correct the pregnancy frequency more accurately in consideration of the past screening result and the current screening result.

また、過去の検診時に記録された妊娠周数から求めた今日の妊娠周数と、今回の検診の計測結果から求めた妊娠周数に相違があった場合に、その統計的平均値のグラフを見ながら、正確な妊娠周数を容易に修正し決定することができる。   In addition, if there is a difference between the number of pregnancy gestations calculated from the number of pregnancy gestations recorded at the previous screening and the number of pregnancy gestations determined from the results of the current screening, a statistical average graph is shown. While observing, the exact pregnancy frequency can be easily corrected and determined.

また、図7には、3つのプロット位置の横に、計測結果と統計的平均から得られる妊娠周数と表示している妊娠周数(あるいは、表示している妊娠周数で計算される過去の検針日の妊娠周数)の日数の差を数値で表示している。図7−1は、第2の実施の形態で説明した妊娠周数変更前のグラフ、図7−2は、妊娠周数変更後のグラフとなっている。日数の差は、患者データ用メモリ15の患者F11の患者属性部22から読み出した妊娠周数と、計測データ部23から読み出した計測結果から中央制御回路11で計算され、この中央制御回路11と中央制御回路11を含む制御系回路部10を設けることにより、妊娠周数を修正しているときに、最初の妊娠周数との差異をグラフと数値(日数の差の値)の両方で確認しながら新たな妊娠周数を決定することができる。   In FIG. 7, next to the three plot positions, the pregnancy frequency obtained from the measurement result and the statistical average and the displayed pregnancy frequency (or the past calculated with the displayed pregnancy frequency). The difference in the number of days of pregnancy) is displayed as a numerical value. FIG. 7-1 is a graph before changing the pregnancy frequency described in the second embodiment, and FIG. 7-2 is a graph after changing the pregnancy frequency. The difference in the number of days is calculated by the central control circuit 11 from the pregnancy frequency read from the patient attribute part 22 of the patient F11 in the patient data memory 15 and the measurement result read from the measurement data part 23. By providing the control system circuit unit 10 including the central control circuit 11, when the pregnancy frequency is corrected, the difference from the first pregnancy frequency is confirmed by both a graph and a numerical value (the value of the difference in days). A new pregnancy frequency can be determined.

また、妊娠周数との差の日数をグラフ上に表示する代わりに、計測結果と統計的平均から求められる偏差をグラフ上に表示すると、妊娠周数を修正しているときに、最初の妊娠周数との偏差とグラフの両方で確認しながら新たな妊娠周数を決定することができる。   Also, instead of displaying the number of days of difference from the pregnancy frequency on the graph, displaying the deviation obtained from the measurement results and statistical averages on the graph allows the first pregnancy to occur when the pregnancy frequency is corrected. A new pregnancy frequency can be determined while confirming both the deviation from the frequency and the graph.

なお、第2の実施の形態の説明では、図5でLMPから計算される妊娠周数をもとに3回目の検診の日付で計算した妊娠周数のプロット位置57、65、66にプロットをしたが、最初のCRLの計測結果と統計的平均値から得られる妊娠周数を、最初の検診のときに、患者データ用メモリ15の患者F11の患者属性部22に記録するようにコントロールできる中央制御回路11を備えていても、同様に実施可能であり、LMPがわからない患者さんの場合であっても、計測結果から求めた妊娠周数と、その統計的平均値のグラフを見ながら、正確な妊娠周数を容易に決定することができる。   In the description of the second embodiment, plots are made at plot positions 57, 65, and 66 of the pregnancy frequency calculated on the date of the third examination based on the pregnancy frequency calculated from the LMP in FIG. However, it is possible to control the gestational frequency obtained from the first CRL measurement result and the statistical average value so as to be recorded in the patient attribute section 22 of the patient F11 of the patient data memory 15 at the first examination. Even if the control circuit 11 is provided, it can be implemented in the same way, and even in the case of a patient who does not know the LMP, while looking at the pregnancy frequency obtained from the measurement result and the statistical average graph, The number of pregnancy laps can be determined easily.

なお、以上の説明では、最初の検診時に、LMPから求めた妊娠周数を患者データ用メモリ15の患者属性部22に記録する例について説明したが、LMPからの計算でなく、妊娠周数を操作卓12の操作で直接、患者データ用メモリ15の患者属性部22に記録するコントロールができる中央制御回路11を備えていても、同様に実施可能であり、検診の最初の問診あるいは過去の検診の情報から決定した妊娠周数と、今回の検診の計測結果から求めた妊娠周数に相違があった場合に、その統計的平均値のグラフを見ながら、正確な妊娠周数を容易に修正し決定することができる。   In the above description, the example in which the pregnancy frequency obtained from the LMP is recorded in the patient attribute section 22 of the patient data memory 15 at the first examination is described. However, the pregnancy frequency is not calculated from the LMP. Even if it has the central control circuit 11 which can be controlled to be recorded in the patient attribute section 22 of the patient data memory 15 directly by operating the console 12, it can be implemented in the same manner. If there is a difference between the number of pregnancy gestations determined from the above information and the number of pregnancy gestations obtained from the results of this screening, the exact number of pregnancy gestations can be easily corrected while looking at the statistical average graph. Can be determined.

なお、以上の説明では、妊娠周数を修正するときには、操作卓12の操作で周数を移動させながら、移動前後のグラフを見比べることで、新たな妊娠周数を決定していたが、操作卓12の操作で、計測結果と統計的平均の妊娠周数と偏差(あるいは両者の妊娠周数の差の日数)を求め、1つのもしくは複数の部位について得た偏差の値(あるいは両者の妊娠周数の差の日数)が、最小になる新たな妊娠周数を決定するコントロールを中央制御回路11で行っても良い。この構成では、誤差の少ない新たな妊娠周数をさらに容易に決定することができる。   In the above explanation, when correcting the pregnancy frequency, the new pregnancy frequency was determined by comparing the graphs before and after the movement while moving the frequency by operating the console 12. The operation of the table 12 is used to obtain the measurement result and the statistical average pregnancy frequency and deviation (or the number of days of the difference between the two pregnancy frequency), and the deviation value obtained for one or more parts (or both pregnancy values). The central control circuit 11 may perform control for determining a new pregnancy frequency that minimizes the difference in the frequency). In this configuration, a new pregnancy frequency with less error can be determined more easily.


以上のように、本発明にかかる超音波診断装置は、計測結果をグラフ上にプロットした後、プロット位置の周数を移動させ、表示する手段を設けることにより、検診を行う期間によらず、正確な妊娠周数を容易に修正し決定することができるという効果を有し、産婦人科での妊婦の検査又は診断に適用される超音波診断装置、または胎児の出産日決定装置等として有用である。

As described above, the ultrasonic diagnostic apparatus according to the present invention, after plotting the measurement result on the graph, moves the frequency of the plot position and provides a means for displaying, regardless of the period of performing the examination, It has the effect of being able to easily correct and determine the exact pregnancy frequency, and is useful as an ultrasound diagnostic device or fetal birth date determination device that is applied to pregnant women's examinations or diagnoses in obstetrics and gynecology It is.
