6 Image Acquisition
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.
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.
Angle
This function is used to adjust the angle between Doppler vector and flow to make the velocity
more accurate.
The real-time adjusting angle value is displayed in the image parameter area.
Quick Angle
Adjusts the angle faster in increments of 60°, and the real-time value of which is displayed in the
image parameter area.
Dynamic Range
The dynamic range conveys the information that being transformed from echo intensity to gray
scale.
