Measurement
Refer to Acceleration Measurement for measuring methods.
HR Measurement
Function: To depict a cardiac cycle through the measurement mark dis-
played in the form of vertical line, based on which the HR can be deter-
mined.

RI (Resistance Index) Measurement
Function: This measurement is used to calculate the resistance index, mea-
suring the peak systole (PS) and the velocity of end diastole (ED) as well as
their velocity rate.
Refer to Velocity Measurement for its measuring methods.
D-Flow and A-Flow Measurement
D-Flow is diameter flow measurement and A-Flow is area flow measure-
ment. The default measurement method can be changed in the Preset or in
the soft menu.
The preset method is: press Config/Dialog key on the keyboard → click
Meas/Text → click General Meas on the sub-menu above the screen, and
change the default settings to the flow measurement method.

Select HR in the main menu.
Roll the trackball to place the caliper on the starting point of the car-
diac cycle on the spectrum, and press Set key on the control panel.
Roll the trackball to place the caliper on the end point of the cardiac
cycle, and press Set key on the control panel.
The measurement results will be displayed in the Measurement re-
sult table.
Making a Diameter Flow Volume Method
Function: Diameter flow is an estimated value of the flow that is calcu-
lated based on the vascular diameter. Diameter flow needs to carry out
the measurement of vascular diameter in B mode with Doppler veloci-
ty tracing.
Select the corresponding menu items on the toggle Flow Vol-
STEP 1
ume, then select D-Flow.
Put the cursor at the starting point of PW mode image, and
STEP 2
press Set key on the control panel.
Roll the trackball to place the cursor on the end point, and
STEP 3
press Set key on the control panel.
Roll the trackball and move the caliper to the B mode image,
