6 Image Acquisition

Auto Calculation

This function is used to trace the spectrum and calculate the PW/CW mode image parameters. The

results are displayed in the results window.

In real-time scanning, the results displayed are derived from the calculation of the latest cardiac

cycle.

In the freeze and cine status, the results displayed are calculated from the current selected area.

• Auto Calculation Parameter: To set the calculation results to display.

• Auto Calculation Cycle: To set the heart cycle number for auto-calculation.

• Trace Area: To set the trace area of the Doppler wave in the spectrum map, applicable for auto

calculation, V Max and V Mean display.

• Trace Smooth: To set the smooth level when tracing.

• Trace Sensitivity: This function is used to set the sensitivity of tracing in the spectrum.

Invert

This function is used to set the display manner of spectrum.

TIP:

It is available only for linear probes.

Speed

This function is used to set the scan speed of PW mode imaging.

T/F Res

Adjusts for a balance between time resolution and spatial resolution.

WF (Wall Filter)

To display the image accurately, it adjusts the cut-off used in the wall filter, and filters out the flow

noise which is produced by vessel wall vibration. The real-time value is displayed in the image

parameter area.

Tint Map

This function provides an imaging process based on color difference rather than gray distinction.

Gray Map

Selects among post processing map curves to optimize grayscale images.

Display Format

Sets the display proportion of PW mode image and B mode image.

Duplex/Triplex

This function is used to set if B image or B+Color image (Power) is scanned synchronously.

HPRF

HPRF mode is used when detected velocities exceed the processing capabilities of the currently

selected PW Doppler scale or when the selected anatomical site is too deep for the selective PW

Doppler scale.

Baseline

Refers to the area where the velocity in zero in the spectrum. The map changes after being edited.
