Diagnosis Mode Types and Control

Diagnosis Mode Type

This product supports a variety of diagnosis modes including Basic mode, Combined mode,

Multi-Image mode, and 3D mode.

■ Basic Mode

2D Mode, Color Doppler Mode, Power Doppler Mode, M Mode, PW Spectral Doppler

Mode.

■ Combined Mode

PW Spectral Doppler Mode is added in Color Doppler Mode or Power Doppler Mode.

2D/C/PW mode or 2D/PD/PW is available.

■ Multi-Image Mode

In Dual Mode you can view two images side by side simultaneously and compare them.

■ 3D Mode

3D images can be obtained. Provides the Freehand 3D option, which allows viewing of

three-dimensional images.

Changing Diagnosis Mode Format

The following section explains how to change the display format that is common to all diagnosis

modes.

▐ Changing Active Image Mode

In combined mode, the control functions and screen menu configuration differ depending

on the active image mode. To change the active image mode press the Set or the Update

button on the control panel.

For example, you can change the currently active image mode in PW Spectral Doppler

Mode Æ 2D Mode order by pressing the Set or the Update button if 2D Mode is activated

in 2D/PW Mode.

However, the Set or the Update button is inactive in Freeze mode.

Chapter4. Diagnosis Modes 4 - 3

Trackball to set the position and size of the Zoom Box.

▐ Color Image Optimization

Changing ROI Box Position

The ROI is the area within the 2D image where color (blood flow) information is displayed

in Color Doppler Mode. Use the Trackball to change the ROI Box position.

Changing ROI Box Size

Enter the ROI Box Size Control Mode by rotating the Menu dial-button without opening the

pop-up menu or pressing the Change button on the control panel. Adjust the ROI Box size

Sensitivity decreases the frame rate.

Balance Control

This function is used to adjust the range of the color image displayed by comparing the

gray level of the 2D image with the Doppler signal value of the color image. If the Balance

value increases, the color image is seen even where the 2D image signal is strong (bright),

thereby increasing the color image range.

Select Balance using the Menu dial-button on the control panel and adjust the value.

Steer Function

When Linear probe is selected, this function adjusts the ultrasound beam angle to prevent

the loss of color information caused by the ultrasound beam angle.

NOTE

For further information about other PD Image optimization, refer to ‘Color

Doppler Mode’.

Chapter4. Diagnosis Modes 4 - 15

PW Spectral Doppler Mode

PW (Pulsed Wave) Spectral Doppler Mode gives information on the speed/direction of blood

flow at a specific site in the form of a spectral trace and audio signal. Since the pulse is

transmitted being divided according to time, distance (depth) information can be obtained. The

mode is suitable for measuring relatively slow blood flow such as that in abdominal and

peripheral vessels. The 2D Mode image is shown simultaneously allowing the marking and

adjustment of specific sites within blood vessels.

▐ PW Spectral Doppler Mode Screen

On the PW Spectral Doppler Mode image, the horizontal axis represents time, and the

vertical axis represents speed (or frequency).

Sample Volume

When Sample Volume is on the blood flow of 2D image, it represents Doppler Spectrum.

Its position is moved with the Trackball and displayed in the [email protected] mm format. The

format means that the Sample Volume of ‘xx.x’ mm size is located at a depth of ‘yy.y’ mm.

For example, [email protected] mm means that the Sample Volume of 2.0mm size is located at a

depth of 16.7mm.

▐ PW Spectral Doppler Mode Format Change

size (Large, Normal, or Small).

This function is activated in Simultaneous mode is on.

Activating Simultaneous Function

The PW Spectral Doppler image and 2D image can be displayed simultaneously or

separately. This function is not available in Steered CW Spectral Doppler Mode.

Select Simultaneous in the menu using the Menu dial-button on the control panel. If

Simultaneous is selected again when this mode is already on, the mode is deactivated.

Activate the Simultaneous function option by setting Simultaneous function as ‘Allow

2D/PW’ or ‘Allow 2D/C/PW’in the Misc. tab in the Setup window.

NB. Simultaneous function decreases Doppler PRF, thus decreasing the measurable

speed range.

Doppler Baseline Control

Press the Flexible soft button [2] Baseline and then use Menu. Turn the Menu dial-

button clockwise to raise the Baseline, and vice versa.

Doppler Axis Invert

Press the Flexible soft button [4] Invert on the control panel. The ‘+ velocity value’ and ‘-

velocity value’, shown at the Doppler axis, change positions.

changed, select the proper value with flexible soft button ([3] -60°, [4] 0°, [5] 60°). Or

use the Menu dial-button to select value from -80°to 80°to adjust the angle for accurate

measurement of speed.

Adjusting the angle of the sample volume helps accurate measurement of speed.

Doppler Sound Volume Control

Select Sound in the menu using the Menu dial-button. Select the value.

Average Control

The Average Control is used to increase spectrum quality.

Select Average in the menu using the Menu dial-button on the control panel. Select the

Average value (Low, Middle or High).

Spectrum Enhancement

The Spectrum Enhancement is used to compensate the signal of low gain Spectral

Doppler Spectrum. This function is available in Loop Only Mode or Simultaneous Function.

value.

HPRF (High PRF) Function

This function measures blood flow whose speed exceeds specified limits at a specified

depth. It doubles the original scale. This function is available only in PW Spectral Doppler

Mode(PW Only).

4 - 18 SONOACE PICO Operation manual

- HPRF Activation

To activate HPRF, increase the Scale values at the required depth. The Phantom Gate

appears over the sample volume in Doppler Line and the scale of Y-axis increase twice.

Once HPRF is activated, the PRF doesn’t increase even if the scale values are raised.

[Figure 4.12 HPRF]

- HPRF Exit

To exit HPRF, decrease Scale values by one notch while HPRF is activated. The

maximum PRF values in PW Spectral Doppler Mode are shown.

- Sample Volume Position Control

To move the Sample Volume position in the PW Only status, the system calculates PRF

values and the Phantom Gate position, and updates them on the PW Spectral Doppler

image. Exit HPRF when HPRF cannot be activated.

When Sample Volume is moved in the 2D Only status, the PRF values don’t change.

NOTE

HPRF is not activated in Simultaneous Mode. It is also not activated if

[PRF*2] exceeds 23KHz.

CAUTION

■ The Phantom Gate position can be located outside the 2D image area in

Zoom Mode.

■ Ensure that the Sample Volume and Phantom Gate are not positioned

over the area to be measured. If more than two SVs are located in the

vessels, all Doppler components will appear in the spectrum, causing

noise.

NOTE
