Calculation Formula & Reference
This section describes the procedure for carrying out obstetric measurements, based on the assumption that the
equipment is in an as-shipped condition.
Descriptions of the basic operations of the measurement functions and each measurement method (mark type =
Caliper, Trace, etc.) are given in the Section 1. “MEASUREMENT FUNCTIONS”.
This section consists of 104 pages.

Cardiac Measurement Functional Outline
4-2-1. Cardiac Measurement Functional List
Cardiology Measurement use studies consisting of various combinations of measurement menu, report display, and
so on, depending upon the part being examined and the purpose of the examination.
[Remark]
When the equipment leaves the factory, it contains “Cardiac Func.” and “Coronary” measurements.
The cardiac measurement is divided as shown in the figure below for each mode.

Description of left ventricle volume measurement
The following description is applicable to the 2B mode using the 2B Mapping function.
When using 2B Mapping, you can display end-diastolic and end-systolic images for the same cardiac cycle.
Use this function to measure the volume of the left ventricle.
Be careful of the following points when performing blood flow measurement related to Doppler.
Angle correction operation:
Before starting Doppler measurement, perform angle correction.
[Remark]
If the Doppler angle exceeds 20 degrees, the accuracy of the measurement results may be adversely affected. For
this reason, we recommend that you project the beam parallel to the blood vessel as far as possible.
Re-using existing measurement values:
You can re-use existing measurement values, so there is no need to repeat the same measurement.
A description of the layout and functions of the switches and keys used for measurement is given in the section entitled, Description of basic operations for, Section 1. “MEASUREMENT FUNCTIONS”.
The measured values of the blood flow values obtained using this equipment are the absolute values displayed on
the observation monitor. They are controlled as positive and negative values for the purpose of calculating the arithmetic index.If the display of each measured value in a report is set to "Average" in a preset, the positive and negative
values are added together and displayed as a mean value. Consequently, when performing multiple measurements
of blood flow on the blood flow waveform drawn using the color Doppler method as a guide, use identical recording
conditions (forward and reverse flow directions) for all of the blood flow waveforms in order to correctly display
each of the arithmetic values arranged in the report.

[Remark]
Arch of the apex cordis:
There is a report to the effect that if the left ventricular long-axis lengths (LVL4d, LVL2s) obtained from the apical
four-chamber or two-chamber cross-section differ from each other by more than 20%, it is conceivable that the correct apex cordis cross-section is not correctly displayed, and that this measurement should not be performed. Display
a correct image of the apex cordis, while referring to the value of %dif shown in the measurement results.
If these diameters differ by more than 20%, the left ventricular volume for each phase will not be calculated. (The
result will appear as ***ml.)
