Description

  The present invention relates to an ultrasonic diagnostic apparatus having a measurement function and a report display function for displaying a measurement result as a report.

  The ultrasonic diagnostic apparatus observes a tomographic image (B mode) of a soft tissue of a living body displayed on a monitor, or arranges the one-line tissue image in parallel along a time axis to change the tissue over time. It is possible to observe a detailed change (M mode) in detail. It is used in a wide range of fields, including the heart, abdomen, mammary gland, urology, obstetrics and gynecology.

  Many of such ultrasonic diagnostic apparatuses measure structural dimensions such as distance, area, and volume from a B-mode image, measure temporal changes from an M-mode image, and perform Doppler mode. It is possible to collect medical information of a plurality of items of a subject by measuring the cardiac output by the method. Various measurement application programs for collecting such medical information are provided, and measurement can be performed along a measurement menu screen.

  Such measurement functions have recently been specialized according to the diagnosis area, and the number of measurement items has become enormous. For example, in the obstetric area (OB: Obstertics), there are the following measurement items.

AA: abdominal cross section AC: trunk circumference APAD: abdominal anteroposterior diameter AFI: amniotic fluid index APTD: trunk anteroposterior diameter BPD: infant head large transverse diameter CER: cerebellum Cervix Len: cervical cervical canal length
Cist.magna: Cerebellar medullary tract Clavicle: Clavicle length CRL: Fetal head kidney length EFW: Estimated body weight
Fetal Ao: fetal aorta FHR: fetal heart rate FTA: trunk cross-sectional area FL: femoral length Fibula: rib foot Foot: fetal foot length GS: fetal sac diameter HA: head sectional area HC: head circumference Humerus: humerus
Kidney: Kidney length Lt Uterin: Left uterine artery MCA: Middle cerebral artery NT: Fetal segment transparency
Ocular D: Eye diameter OFD: Front and rear head diameter OOD: Binocular outer diameter
Radius: Rib Rt Uterin: Right uterine artery TAD: Abdominal width TC: Thoracic circumference THD: Thorax diameter
Tibia: Tibia TTD: Trunk width
Ulna: Ulna Umb A: Umbilical artery Umb VD: Umbilical vein diameter
Yolk Sac: Yolk Sac By the way, improvement of operability is always required for this kind of ultrasonic diagnostic equipment, and as part of this, measurement items are measured on the TCS (Touch Command Screen) which is the display on the console. In general, a function is provided in which a user touches a desired item with a fingertip to measure the item and collect medical information of the subject. In addition, when displaying the measurement menu, there are a type that enumerates all measurement items that can be measured and a type that displays the necessary measurement items separately according to the examination contents. In the latter case, for example, a fetal growth measurement menu The menu is divided into an early pregnancy menu, a late pregnancy menu, a Doppler menu, a menu that is not normally measured, and the like.

  As an example of a conventional measurement menu displayed on the TCS for reference, an early pregnancy menu is shown in FIG. In FIG. 7, 100 is a menu selection unit, 200 is a measurement item unit, 300 is a control selection unit, and 400 is a fetus switching unit. For example, each of up to four children can be measured. In addition, the currently selected item is colored and displayed.

In addition, as a measure to improve operability, users (physicians, laboratory technicians, etc.) enter the subject's ID to selectively display a measurement menu suitable for the subject on the TCS, and to make a number of measurements. Among the items, only the necessary measurement items are displayed, and unnecessary measurement items are hidden so that the measurement function can be selected efficiently (for example, Patent Document 1). reference.).

  By the way, when necessary measurement is performed along the measurement menu and medical information of the subject is obtained, the result is displayed on the TCS on the console as a report in a predetermined format. In this case, if many items are measured, the report may not be able to fit on one screen of the TCS and may be spread over a plurality of pages. Therefore, users such as doctors and laboratory technicians have to check data as measurement results while switching and displaying reports of a plurality of pages, and there is a problem that confirmation of measurement results takes time and effort.

  In addition, measurement items for obtaining an appropriate diagnosis result largely depend on the knowledge and experience of a user such as a doctor, and when there are many measurement items, there is a possibility that the measurement may be terminated without noticing a measurement omission.

  The present invention has been made for the purpose of solving such problems.

In order to solve the above-described problem, the invention described in claim 1 generates an ultrasonic image of a subject based on transmission / reception of ultrasonic waves, and medical treatment of a plurality of items of the subject from the generated ultrasonic image. An ultrasonic diagnostic apparatus that measures information along a measurement menu screen includes report display means for displaying a result of the measured medical information as a report, and the report display means is defined as a normal range of the medical information. Only the medical information deviating from the measured value is selectively displayed, and the medical information registered by the user to be evaluated in combination with the medical information is displayed.

Further, the invention according to claim 2 is registered by a user who should be evaluated together in diagnosis by selecting the medical information item displayed by the report display means in the ultrasonic diagnostic apparatus according to claim 1. has been out of the medical information, the instrumented other medical information item medical information items and unmeasured, characterized by being adapted to identifiably displayed on the measurement menu screen.

According to a third aspect of the present invention, in the ultrasonic diagnostic apparatus according to the first or second aspect, the normal range and the diagnosis of the medical information displayed on the report display means are defined. Another feature is that the user can arbitrarily register other medical information items to be evaluated together .

  As shown in the section of the means for solving the above problems, according to the invention of each claim described in the claims of the present invention, the following effects can be obtained.

According to the first aspect of the present invention, as the report for evaluating the measurement result, only the measurement result out of the definition of the normal range that needs to be focused on is displayed. Data can be provided, measurement results can be easily checked, the burden on the user can be reduced, and in addition to medical information that deviates from the value defined as the normal range, the above-mentioned medical information and diagnosis are evaluated together Since the medical information registered by the user to be displayed is displayed, it is possible to greatly reduce the burden on the user's thought process and to obtain a more reliable diagnosis result.

According to the invention described in claim 2, among the medical information registered by the user to be evaluated together on the measurement menu screen , the measured medical information item and the other unmeasured medical information items are displayed on the measurement menu screen. Since it is displayed so that it can be easily identified, measurement leaks can be reliably prevented, better diagnostic results can be obtained, and the burden on the subject accompanying remeasurement can be prevented. .

According to the third aspect of the present invention, the evaluation data that the user, who is supported by a long experience or the like, thinks that it is optimal can be used, so that a better diagnosis result can be obtained.

  Hereinafter, an embodiment of an ultrasonic diagnostic apparatus according to the present invention will be described in detail with reference to FIGS.

  FIG. 1 is a system diagram shown for explaining a schematic configuration of an embodiment of an ultrasonic diagnostic apparatus according to the present invention.

  This ultrasonic diagnostic apparatus is an ultrasonic probe 1 (hereinafter simply referred to as a probe) for acquiring biological information as an acoustic signal from a subject by transmitting and receiving ultrasonic waves to and from the subject. An ultrasonic wave is transmitted by applying a drive signal to the probe 1 and a transmission / reception circuit 2 for receiving an echo signal from the subject, and an observation condition set for a signal received by the transmission / reception circuit 2 DSC (Digital scan converter) circuit 3 that performs various processes based on the above, an image collection circuit 4 that collects images from the DSC circuit 3, and an image collected by the image collection circuit 4 A graphic memory 5; an image display circuit 6 for taking out an image from the graphic memory 5 and enabling display; and an image signal obtained from the image display circuit 6 and the DSC circuit 3 A control having an output signal switching circuit 7 for switching and supplying to the monitor 8, a CPU for organically controlling these circuits and graphic memory, a memory for recording various measurement items, measurement menus, subject information, and the like Unit 9 and a TCS (Touch Command Screen) 10a for displaying a measurement menu, a report, and the like. The TCS 10a is touch-operated to exchange command signals with the control unit 9 and perform control. An operation console 10 having a numeric keypad, a trackball, various switches and the like for supplying a user command signal to the unit 9 is provided.

  In the ultrasonic diagnostic apparatus according to the present invention configured as described above, when various measurements are performed in accordance with the collection of ultrasonic images, a measurement menu is displayed on the TCS 10a of the console 10, and the measurement menu is followed. Will be executed. For example, if the subject is a person in early pregnancy, the early pregnancy menu shown in FIG. 7 is displayed, and GS (fetal sac diameter), CRL (fetal head kidney length), BPD (child head large lateral diameter),...・ Measure such as. The measurement result is stored while being sequentially compared with the normal range data held in the control unit 9, and the comparison result with the measurement value and the normal range data is displayed on the TCS 10a as a report.

  Such functions are the same as the conventional ones, but the feature of the present invention is that, apart from the normally created report, the measurement items that are out of the normal range definition by comparison with the normal range data among the measurement values By displaying only the measurement item and selecting that item, it is possible to display the measurement results for the measurement items that should be evaluated together for diagnosis, and to support a more appropriate diagnosis, For measurement items that are out of the definition of the normal range, the measurement items that should be measured in order to make a diagnosis are specified to prevent the occurrence of measurement leakage.

  Next, the operation of the ultrasonic diagnostic apparatus according to the present invention having such a function will be described with reference to the flowchart shown in FIG.

  First, in step 1, a measurement menu is displayed on the TCS 10a, and measurement is performed along the menu (step 2). When the measurement is completed, the report creation function is activated as step 3. Then, the process proceeds to step 4, and the results of only the measurement items that are out of the normal range definition are displayed on the report screen of the TCS 10a. In addition, when starting a report, you can select whether to default the screen that displays all measurement results or the screen that displays only the results of measurement items that are out of the normal range definition, using presets, etc. Is possible.

  FIG. 3 shows a report screen displaying the results of only the measurement items that are out of the normal range definition as step 4. Here, as an example of the measurement result for fetus A in the obstetrics area, BPD (child head large horizontal diameter) is considered as a case where only BPD (child head large horizontal diameter) is out of the definition of the normal range among the measurement items. The measured value was 59.0 mm, and the defined normal range was 40.0 to 55.0 mm. Note that this normal range is not uniquely defined, but is defined in various ways by a large number of authors. Which author definition is adopted is determined by the user and is uniquely defined by the user. You may register.

  Here, the user can confirm the measurement results of the measurement items that should be evaluated together for diagnosis based on the result that the BPD (large size of the baby head) is out of the normal range. In this case, the selection may be made by touching “BPD” on the screen of the TCS 10 a with a finger or the like as step 5. By this operation, the process proceeds to step 6, and the screen of the TCS 10a is changed to a report screen as shown in FIG.

  In other words, in addition to the measurement results of BPD (large child head horizontal diameter), the report screen includes measured AC (trunk circumference) and FL (femoral length) as measurement items to be evaluated together for diagnosis. ) And the data indicating the normal range are added and displayed. As a result, the user has already measured AC (trunk circumference) and FL (femur length) as measurement items that need to be evaluated together for diagnosis, and both measured values are within the normal range. I can confirm that.

  In this case, when returning to the measurement menu screen, the screen is as shown in FIG. 5. In FIG. 5, 100 is a menu selection unit, 200 is a measurement item unit, 300 is a control selection unit, and 400 is a fetus switching unit. Represents. The selected item “BPD” in the measurement item portion 200 is displayed in blue, for example, and the measured items “AC” and “FL” are displayed in green, for example. Other unmeasured items are not specially colored and are in a normal display state.

  However, for example, if HC (child head circumference) is required as a measurement item to be evaluated but this item has not been measured, the item “HC” on the measurement menu screen is displayed in red, for example. By displaying (step 7), the user is warned so that there is an item of measurement loss and which item is the item at a glance. In this way, since the item of measurement leakage can be known at a glance, the user can perform additional measurement (step 8), reliably preventing measurement leakage and ending a series of measurements. And better diagnostic results can be obtained.

  FIG. 6 shows an example of a registration screen when the user independently registers the normal range data of the inspection items and the items to be measured. Here, for the measurement item “BPD”, the registration field of the normal range data for each pregnancy week and the case where “HC”, “AC”, “FL” are registered as items to be measured are shown. Other measurement items can be registered in the same manner.

  As described above in detail, according to the present invention, as the report for evaluating the measurement result, only the measurement result that is out of the definition of the normal range that needs to be focused on is displayed, so that the point is simplified. Can be provided to the user. In addition, when the measured value is out of the normal range, the item to be measured for the diagnosis is clearly indicated, and whether or not the item has been measured and the result is displayed if measured. Therefore, it is possible to prevent measurement leakage and obtain a better diagnostic result.

It is the systematic diagram shown in order to demonstrate the schematic structure of one Example of the ultrasound diagnosing device which concerns on this invention. 5 is a flowchart shown for explaining the flow of operation of the ultrasonic diagnostic apparatus according to the present invention. It is the figure which showed an example of the report screen which displayed the result of only the measurement item from which the definition of the normal range was removed. It is the figure which showed an example of the report screen which wrote together the measurement item which should be evaluated together for a diagnosis. It is the figure which showed an example of the measurement menu screen. It is the figure which showed an example of the registration screen in case a user registers the data of the normal range of an inspection item uniquely, and the item which should be measured together. It is the figure which showed the pregnancy early menu as an example of a measurement menu screen.
