Rotate Select knob to highlight the [Scan Scope] menu item, press Select knob item to confirmation select
[Scan Scope] item, and then Rotate Select knob to adjust it.
6.1.2.10 Adjusting the Scan Density
Line density refers to the amount of ultrasound beam that makes up the image. Increasing the value
of line
density improves the resolution and decreases frame rate. Therefore, you have to balance the
frame rate and
the image quality when adjusting the line density.
Steps:
Move cursor to [Scan Density] menu item and press Set key to adjust it.
Rotate Select knob to highlight the [Scan Density] menu item, press Select knob item to confirmation
select [Scan Density] item, and then Rotate Select knob to adjust it.
6.1.2.11 Adjusting the Noise Repression

Steps:
Move cursor to [Scan Density] menu item and press Set key to adjust it.
Rotate Select knob to highlight the [Speckle Reduction] menu item, press Select knob item to
confirmation select [Speckle Reduction] item, and then Rotate Select knob to adjust it.
6.1.2.12 Adjusting the Frame Persistance
Persistence is used to average consecutive frames to provide a smoother appearance with less noise.
Use lower persistence values for fast-moving organs or tissues and higher persistence values for
smoother appearance.
Steps:
Move cursor to [Frame Average] menu item and press Set key to adjust it.
Rotate Select knob to highlight the [Frame Average] menu item, press Select knob item to
confirmation select [Frame Average] item, and then Rotate Select knob to adjust it.
6.1.2.13 Adjusting the Line Average

smoother image.
Steps:
Move cursor to [Line Average] menu item and press Set key to adjust it.
Rotate Select knob to highlight the [Line Average] menu item, press Select knob item to confirmation
select [Line Average] item, and then Rotate Select knob to adjust it.
6.1.2.14 Enabling/Disabling the Compound Imaging
Compound imaging is used to acquire a series of overlapping image frames from substantially differing spatial
directions and combining these images to reduce speckle and improve contrast resolution.
Steps:
Move cursor to [Space Compound] menu item and press Set key to enable or disable it.
Rotate Select knob to highlight the [Space Compound] menu item, press Select knob item to
confirmation select [Space Compound] item, and then Rotate Select knob to enable or disable it.
