Imaging

3 Press the MMODE key.

The time scale above the trace has small marks

at 200ms intervals and large marks at

one-second intervals.

4 Do any of the following as needed:

• Select the sweep speed (Slow, Med,

or Fast).

•Press the

UPDATE key to toggle between the

M-line and M-Mode trace.

• If using a duplex layout, press the

MMODE

key to toggle between the full-screen

M-line and the duplex layout.

To set a duplex layout, see “Presets

setup” on page 22.

CPD and color Doppler imaging

Color power Doppler (CPD) and color Doppler

(Color) are optional features.

CPD is used to visualize the presence of detectable

blood flow. Color is used to visualize the presence,

velocity, and direction of blood flow in a wide range

of flow states.

To display the CPD or Color image

1 Press the COLOR key.

A ROI box appears in the center of the 2D

image.

2 Select CPD or Color.

The current selection also appears in the upper

left-hand screen.

The Color indicator bar on the upper left-hand

screen displays velocity in cm/s in Color imaging

mode only.

3 Using the touchpad, position or resize the ROI

box as needed. Press the

SELECT key to toggle

between position and size.

While you position or resize the ROI box, a green

outline shows the change. The ROI box indicator

on the left-hand screen shows which touchpad

function is active.

4 Adjust controls as desired. See “CPD and

Color controls.”

CPD and Color controls

In CPD or Color imaging, you can set the following

on-screen controls.

Color, CPD Toggle between CPD and Color.

The current selection appears in

the upper left-hand screen.

Color

Suppress

Shows or hides color information.

You can select Show or Hide

while in live or frozen imaging. The

setting shown on-screen is the

current selection.

Flow

Sensitivity

The current setting appears

on-screen.

• Low optimizes the system for

low flow states.

• Med optimizes the system for

medium flow states.

• High optimizes the system for

high flow states.

PRF Scale Select the desired pulse repetition

frequency (PRF) setting by

pressing the control keys.

There is a wide range of PRF

settings for each Flow Sensitivity

setting (Low, Med, and High).

Available on select transducers.

Wall Filter Settings include Low, Med, and

High.

Available on select transducers.

Steering Select the steering angle setting of

the color ROI box (-15, 0, or

+15). If adding PW Doppler, see

“PW Doppler controls” on

page 29.

Available on select transducers.
