Description

  The present invention relates to an ultrasonic diagnostic imaging apparatus having a measurement function.

  The ultrasonic diagnostic imaging apparatus observes a tomographic image (B mode) of a soft tissue of a living body, or arranges one line of tissue images in parallel along the time axis to change the morphology of the tissue over time ( M mode) can be observed 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 imaging apparatuses can measure structural dimensions such as distance, area, and volume from a B-mode image, and can measure temporal changes from an M-mode image. Various application programs for measurement are provided for this purpose. Such measurement functions have recently been specialized according to the diagnosis area. 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

Tibia: Tibia TTD: Trunk width
Uina: Ulna Umb A: Umbilical artery Umb VD: Umbilical vein diameter
Yolk Sac: Yolk Sac By the way, improvement of operability has always been demanded for this kind of ultrasonic diagnostic imaging equipment, and recently, as part of this, test items are displayed as measurement menus on TCS (Touch Command Screen), Generally, a function is provided so that an operator can measure a desired item by touching the desired item with a fingertip. In addition, when displaying the measurement menu, there are a type that enumerates all the test items that can be measured and a type that displays the necessary test items separately according to the test 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.

  For reference, examples of conventional menus displayed on the TCS are shown in FIGS. 4 is an early pregnancy menu, FIG. 5 is a late pregnancy menu, FIG. 6 is a Doppler menu, and FIG. 7 is a menu that is not normally measured. Although not shown, there are various patterns that are uniquely divided by the author. In each of these drawings, 100 is a menu selection unit, 200 is an inspection item unit, 300 is a control unit, and 400 is a fetus switching unit. For example, up to four children can be inspected. The currently selected item is displayed in a colored manner.

Furthermore, as a measure for improving the operability, the operator (surgeon) inputs the subject's ID to selectively display an examination menu suitable for the subject on the TCS, and to display a number of examination items. Among them, there has been proposed an apparatus in which only necessary inspection items are displayed and unnecessary inspection items are hidden so that inspection functions can be selected efficiently (for example, see Patent Document 1). ). According to this technique, for example, it is possible to determine whether a subject who has consulted obstetrics is in the early pregnancy stage or in the middle of pregnancy and to display a menu suitable for it.
JP 2001-299749 A (3rd page, FIG. 4)

  By the way, when carrying out fetal growth measurement using an ultrasonic diagnostic imaging apparatus, it is possible to determine the pregnancy time based on the subject's ID information and automatically display, for example, an early pregnancy menu as a test menu on the TCS. it can. Therefore, the surgeon usually performs various measurements using this menu.

  However, there are some pregnant women who are at risk (hereinafter referred to as high-risk pregnant women) and those who are not, and high-risk pregnant women have more items to be examined than those without risk. Necessary. Therefore, the surgeon needs to select the necessary items from the menu that is not normally measured in addition to the initial pregnancy menu for high-risk pregnant women, while conscious of whether or not they are high-risk pregnant women. It was. Therefore, there is a problem that the surgeon neglects to be recognized as a high-risk pregnant woman or forgets to make necessary measurements. In addition, there is a possibility that there are cases where items to be checked are not checked while being recognized as a high-risk pregnant woman and performing various measurements.

  The present invention has been made to solve such problems.

In order to solve the above-described problem, the ultrasonic diagnostic apparatus according to the present invention performs fetal measurement by transmitting and receiving ultrasonic waves to and from a subject, and acquires a plurality of items of medical information based on the fetal measurement. An ultrasonic diagnostic imaging apparatus having a measurement function for storing a plurality of measurement items and storage means for storing high-risk criterion data, and including at least the age of the subject and the number of miscarriages of the subject Information acquisition means for acquiring information unique to the person, information specific to the subject acquired by the information acquisition means, and the high-risk determination reference data, and based on the comparison result, Determination means for determining whether or not the subject has a risk, and the risk of the subject from the measurement items stored in the storage means based on the determination by the determination means Measurement items according to An extraction measuring item extraction means, characterized by comprising a display means for displaying a measurement item extracted by the measurement item extracting means as a measurement menu.

  As indicated in the section of 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 present invention, the measurement item for high-risk pregnant women is displayed as a menu in the case of a subject (high-risk pregnant woman) who is at risk based on the subject's personal information, It is possible to reliably prevent omissions in measurement items specific to high-risk pregnant women due to cognitive omissions as well as omissions in cognition of being high-risk pregnant women.

  Hereinafter, an embodiment of an ultrasonic diagnostic imaging apparatus according to the present invention will be described in detail with reference to FIGS. 1 to 3.

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

  This ultrasonic diagnostic imaging apparatus transmits and receives ultrasonic waves to and from a subject, thereby acquiring an ultrasonic probe 1 for acquiring medical information from the subject, and the ultrasonic probe 1. Based on the transmission / reception circuit 2 for receiving the echo signal from the subject and the observation condition set for the signal received by the transmission / reception circuit 2 A DSC circuit 3 that performs various processes, an image collection circuit 4 that collects images from the DSC circuit 3, a graphic memory 5 that stores images collected by the image collection circuit 4, and an image that is extracted from the graphic memory 5 A recording image display circuit 6 for enabling display, an output signal switching circuit 7 for switching an image signal obtained from the recording image display circuit 6 and the DSC circuit 3 and supplying the image signal to the monitor 8, and each of these circuits and graphics. Between the control unit 9 having a CPU for organically controlling the memory and a memory for recording various measurement items, measurement menus, subject information, and the like, and the control unit 9 provided with the TCS 10a by touching the TCS 10a A console 10 is provided for sending and receiving command signals.

  Next, the operation of the ultrasonic diagnostic imaging apparatus in such an embodiment will be described based on the flowchart shown in FIG.

  First, in step 1, a subject ID is input by operating a numeric keypad provided on the console 10 or the like. This subject ID is compared with the subject data stored in the control unit 9 to determine whether or not this is the first visit (step 2). When it is determined that the patient is a first visitor, the process proceeds to Step 3 and medical information necessary for diagnosis regarding the subject, for example, in obstetrics, age, last menstruation start date, obstetric history (number of pregnancy, normal childbirth, Enter the number of miscarriages, abortions, etc.), past medical history, family medical history, etc.

  On the other hand, if it is determined in step 2 that the person is not a first visitor (that is, a reexamination person), the process proceeds to step 4 to call the subject information already registered in the control unit 9. That is, information specific to the subject is acquired here. Then, as Step 5, based on the called subject information for the revisited person and the subject information input in Step 3 for the first-examined person, it is compared with the high risk criterion data already registered in the control unit 9. To do. Here, if the high-risk criteria data is included in the subject information, it is determined that there is a high-risk subject (high-risk pregnant woman), and if not, the risk is If no high risk is set as being a subject who does not have a high risk, and if high risk is set, then in step 6, what (if there is more than one) of the subject information is high risk. A program is set up to set the basis for determining whether or not it is determined. It is possible to default to a definition standard with high risk.

  Through such steps, in step 7, it is automatically determined whether the subject is a high-risk pregnant woman. If it is determined that the subject is a pregnant woman who has no risk, a normal measurement menu is displayed on the TCS 10a as step 8. This measurement menu is, for example, as shown in FIGS. As a result, the surgeon proceeds to step 12 and performs an examination along the displayed measurement menu, and the result is compiled into a diagnostic report.

  On the other hand, when it is determined in step 7 that the subject is a high-risk pregnant woman, in step 9, a measurement menu for high-risk pregnant women is displayed on the TCS 10a. The measurement menu for high-risk pregnant women displayed in this step 9 includes, as shown in FIG. 3, for example, items that are usually measured, in addition to BPD, HC, AC, FL, Umb A, MCA, and high-risk pregnant women. For this purpose, Ocular D, OOD, Cist Magna, NT, TC, Rt Uterin, Lt Uterin, Fetal Ao, etc. have been added. At this time, in order to make the operator strongly recognize that the subject is a high-risk pregnant woman, this fact is displayed on the monitor 8 and the TCS 10a. Of course, an alarm sound may be emitted. In FIG. 3, reference numeral 500 denotes a measurement technique switching unit, and other parts that are the same as those in FIGS. 4 to 7 are given the same reference numerals.

  Therefore, the surgeon proceeds to step 12 and performs an examination according to the measurement menu for high-risk pregnant women displayed on the TCS 10a as shown in FIG. 3, for example. If the table 10 is operated (step 10), the information on which the subject is determined to be a high-risk pregnant woman in step 7 can be displayed on the monitor 8 (step 11). That is, when it is determined in step 7 that the subject is a high-risk pregnant woman, a mark or the like indicating that is displayed on the TCS 10a. Can be displayed. In addition, when the high-risk pregnant measurement menu is displayed without waiting for the operator's operation, the apparatus side may display the determination basis unilaterally. By doing so, the surgeon can carefully perform the examination after clearly recognizing that the subject is a high-risk pregnant woman and what kind of risk it has.

  Now, whether it is a normal subject or a subject who is at risk, the test is performed along the displayed measurement menu as step 12, and if there is no particular problem, the test is terminated. However, during the examination, from the measurement data, the normal subject was registered as a high-risk pregnant woman, or conversely, the subject who was a high-risk pregnant woman was deregistered as a high-risk pregnant woman because the risk was resolved. May be appropriate. It may also be necessary to change the risk basis for high-risk pregnant women. In the present invention, such a case can be dealt with.

  That is, as a result of the inspection in step 12, the operator determines that the subject needs to be newly registered as a high-risk pregnant woman, or determines that registration as a high-risk pregnant woman should be cancelled. If so, the console 10 is operated as a step 13 to call the high risk registration change function. Thereby, the high risk registration change screen is displayed on the monitor 8 or the TCS 10a (step 14). Therefore, based on the high risk registration change screen, the surgeon changes the setting of items related to risk for the patient information of the subject (step 15). This changed content is immediately reflected in the patient information of the subject. Of course, standard high-risk pregnant measurement items can be added or deleted to make them suitable for the subject, and user-specific items can be added. It is also possible to customize measurement items for high risk.

  On the other hand, the basis for changing the registration for high risk is also changed based on the previous high risk registration change screen (step 16). Here, as a basis for defining the high risk, a user-specific item may be added to a standard item, and a function for returning a user-changed item to a standard definition may be provided. The contents of the change in step 16 are surely reflected in the next examination of the subject, and the examination ends.

  As described above in detail, according to the embodiment of the present invention, a measurement menu suitable for the subject is presented based on the personal information of the subject, and this is also warned in the case of a high-risk pregnant woman. Therefore, forgetting measurement due to a simple mistake of the surgeon, missing measurement due to recognition error of being a high-risk pregnant woman, missing measurement due to misidentification of the subject, etc. Can be prevented. In addition, in the course of follow-up, if a high-risk pregnant woman is reconsidered, it is possible to promptly take measures such as registering as a high-risk pregnant woman or canceling the registration of a high-risk pregnant woman. It can contribute to improvement. Furthermore, since high-risk measurement items can be customized, it is possible to perform examinations suitable for high-risk pregnant women, increase the degree of freedom of examination, and contribute to improving the management and care of high-risk pregnant women.

It is the systematic diagram shown in order to demonstrate the schematic structure of one Embodiment of the ultrasonic image diagnostic apparatus which concerns on this invention. Example 1 3 is a flowchart shown for explaining the operation in the embodiment of the ultrasonic diagnostic imaging apparatus according to the present invention. Example 1 It is the figure which showed an example of the measurement menu for high-risk pregnant women in embodiment of this invention. Example 1 It is the figure which showed the pregnancy early menu among the conventional fetal growth measurement menus. It is the figure which showed the late pregnancy menu among the conventional fetal growth measurement menus. It is the figure which showed the Doppler menu among the conventional fetal growth measurement menus. It is the figure which showed the item menu which is not normally measured among the conventional fetal growth measurement menus.
