 M Distance

This is a basic measurement that is available in M Mode only. You can specify two points in an M image

and measure the distance, elapsed time and velocity between them.

1. Press the Softmenu button [1] Distance to select M Distance. “M Distance” is displayed on the left

side of the screen.

2. Specify two points and measure the straight distance between them. The method for measuring a

line is the same as in “2D Distance (Line).”

3. When the measurement is nished, its result is shown on the screen.

 Doppler Velocity

This is a basic measurement that is available in Spectral Doppler Mode only. You can specify two points

in a Spectral Doppler image and measure the distance between them, and the velocity at each point

to calculate the velocity change, time change and acceleration.

NOTE: In a Spectral Doppler image, the X- and Y-axes represent time and velocity, respectively.

You can measure acceleration for up to two segments and dierentiate the points of segments into

Point 1 and 2.

1. Press the Softmenu button [1] Distance to select Doppler Velocity. “Doppler Velocity” is displayed

on the left side of the screen.

2. Specify two points and measure the straight distance between them. The method for measuring a

line is the same as in “2D Distance (Line).”

3. When the measurement is nished, its result is shown on the screen.

▶

V1: Velocity at Point 1

▶

V2: Velocity at Point 2

▶

RI: Resistivity Index

▶

V1/V2: The Ratio of Velocity

▶

dV: Change in Velocity

▶

dT: Change in Time

▶

Acc: Acceleration
