[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic diagnostic apparatus for transmitting an ultrasonic wave from an ultrasonic probe to a subject and obtaining an ultrasonic image based on reflected ultrasonic waves from the subject, and particularly for the subject. The present invention relates to an ultrasonic diagnostic apparatus accompanied by measurement.

2. Description of the Related Art Conventionally, in this type of ultrasonic diagnostic apparatus, in addition to the measured value of the subject, a standard value is displayed, a normal range is displayed, and the measured value is not within the normal range. There were things such as displaying it with a mark.

[0003]

However, in the above-mentioned conventional ultrasonic diagnostic apparatus, the inspector reads a standard value or a numerical value indicating a normal range, in addition to the measured value, and further compares the measured value with the measured value to judge the magnitude. However, there is a problem that the burden on the inspector is large. In addition, in the ultrasonic diagnostic equipment that displays the judgment of normality or abnormality with a mark, even if the mark is not displayed because it is judged to be normal, if the measured value is within the normal range, the cause of the subject to be abnormal in the future There was a fear that the person might overlook.

The present invention is intended to solve such a conventional problem, and an object thereof is to provide an excellent ultrasonic diagnostic apparatus capable of reducing the burden on the inspector and making an accurate diagnosis. To do.

[0005]

In order to achieve the above-mentioned object, the present invention was calculated from statistical values and measured values corresponding to the standard distribution function of the object in addition to displaying the measured values for the object. The statistics are displayed together. Further, when the measured value is out of the normal range, a warning sound is generated to warn that.

[0006]

Therefore, according to the present invention, it is possible to immediately recognize where the measured value is located with respect to the standard distribution, and to easily determine the degree of normality or abnormality of the subject and the magnitude relationship with the standard value. , The alarm sound can immediately reveal the abnormality or measurement error of the subject.

A warning sound is generated by the signal from 3.

Next, the operation of the above embodiment will be described.
Ultrasonic waves are emitted to the diagnostic region of the subject, and the ultrasonic image processing unit 1 performs ultrasonic image processing on the diagnostic region by reflected ultrasonic waves from the subject. In addition, the diagnostic region of the subject is measured by the measuring unit 2, and the measured value is converted by the measured value display output unit 3 into character data that can be displayed by the character generator. On the other hand, by the input from the keyboard 5, the LMP, the diagnostic part, and the warning sound generation value setting unit 4
P, the type of diagnostic part, the value that should generate a warning sound,
From these values, the average value / standard deviation value generation unit 6 outputs the average value and standard deviation value. Average and standard deviation value generator 6
Then, as shown in FIG. 2, the LMP is input to a table or a mathematical expression selected according to the type of the diagnosis site, and the average value and the standard deviation value are output. In addition, here, it is assumed that the distribution of the measured values follows the normal distribution, but if the measured values follow another distribution, for example, the Weibull distribution, those characteristic parameters can be used. The percentile calculation unit 7 is a percentile indicating where the statistical population is located from the average value, the average value and the standard deviation value from the standard deviation value generation unit 6, and the actual measurement value from the measurement unit 2,
For example, the shaded portion in FIG. 3 is calculated, and the percentile display output unit 8 converts this into a displayable signal. The outputs of the ultrasonic image processing unit 1 and the measurement value display output unit 3 are added by the adder 9, and the output of the adder 9 and the output of the percentile display output unit 8 are added by the adder 10, and the monitor 11 The measurement value and the statistical value are displayed visually on the screen as shown in FIG. 4, for example, together with the ultrasonic image. In the example of FIG. 4, since the percentile value with respect to the diagnostic site FOD is small, there is a possibility of an abnormal diagnostic site or measurement error.

The statistical value output from the percentile calculation unit 7 and the warning sound generation value indicating the normal range preset by the LMP, the diagnostic site, and the warning sound generation value setting unit 4 are input to the comparison unit 12. Are compared, and it is determined whether or not the measured value obtained from the measuring means 2 is within the normal range. If the measured value is not within the normal range, the warning sound generating unit 13 generates a warning sound from the speaker 14.

You can easily determine the magnitude relationship with the standard value,
An alarm sound from the speaker 14 enables immediate determination of abnormality or measurement error of the subject.

In the above embodiment, the percentile value corresponding to the normal distribution is displayed on the monitor 11. However, as shown in FIG. 5, when the ratio to the standard deviation and the measured value follow another distribution. Needless to say, those characteristic values may be displayed on the display.

[0012]

As described above, according to the present invention, since the statistical value of the measured value is displayed in addition to the measured value of the subject, the information amount for the diagnostic site is increased as compared with the conventional one, and the standard The difference between the values can be intuitively determined, and the subject can be easily and accurately diagnosed, and the diagnostic time can be shortened. In addition to displaying statistical values, by issuing a warning sound when the measured value exceeds the normal range, it is possible to immediately judge abnormalities and measurement errors in the diagnosis area and eliminate unnecessary remeasurement.
