Means for storing the result of the volume calculation, and
Ultrasound diagnostic equipment with means for searching based on the result of calculation
Place. (Background of Appendix 3)
Is disclosed in JP-A-62-97542. JP-A-62-97
The problem of 542 is that the disease name and / or
Search by symptom is not possible.
It is difficult to grasp the direction and it may be difficult to contribute to improving the therapeutic effect
That is. (Purpose of Appendix 3) Existence of the result of the volume calculation
It is an object of the present invention to provide an ultrasonic diagnostic apparatus having an effective use means. (Operation of Appendix 3) Data is calculated based on the result of volume calculation.
Data and search for disease names and / or
Search by example allows you to search for disease names and / or trends by case.
It is easy to chew and can contribute to the improvement of therapeutic effects
is there. 4. Ultrasound diagnosis characterized in that a pointer is displayed on a screen according to Supplementary Note 1.
Cutting device. (Background of Appendix 4)
Is disclosed in JP-A-55-94246. JP-A-55-94
The problem of 246 is that the cursor position is a planar image in the tomographic image.
Because the display position is limited, the degree of freedom of the cursor is poor
Less means for explanation, less persuasiveness,
It is possible that (Purpose of Supplementary Note 4)
By providing an ultrasonic diagnostic device with explanation means
is there. (Operation of Appendix 4) A pointer is always displayed on the monitor.
Is displayed and can be moved freely with a mouse etc.
Therefore, a means for explanation is provided, and a convincing explanation is possible.
It is a capability. According to the present invention as described above,
Manual and / or automatic tracing of the region of interest on the layer image
And the area of the region of interest based on the trace information.
Means for performing arithmetic operation and when the ultrasonic transmission / reception unit makes one rotation
Means for arithmetically calculating the volume from the distance traveled and the area.
Performing multiple volume calculations in an ultrasound diagnostic apparatus
Multiplying means, and calculating an average value of the results of the plurality of volume calculations
And means for calculating the average value
Extremely accurate body to calculate the average value of the result of volume calculation
Product measurements can be made.
