To adjust LGC:
●
Tap
LGC L
on the touch screen to change the gain on the left part of the ultrasound image.
●
Tap
LGC R
on the touch screen to change the gain on the right part of the ultrasound image.
■ Focal Position/Number/Span
The focal position/number/span is used to tighten up the beam for a specic area and the focus identied by a red
triangle is displayed on the right side of the image.
Focus optimizes the image by increasing the resolution for a specic area.
To adjust the focal position/number/span:
●
Tap the left or right part of
Focus
on the touch screen to decrease or increase the depth of focal zone(s).
●
Tap the left or right part of
Focal Num
on the touch screen to decrease or increase the number.
●
Tap the left or right part of
Focal Span
on the touch screen to decrease or increase the value.
■ Depth
Depth is used to adjust the distance over which the B-Mode image is anatomized.
To adjust the depth:
●
Rotate the
Depth
knob on the control panel clockwise to increase the depth range of the 2D image and the size
of image is reduced to display the entire ultrasound image.
●
Rotate the
Depth
knob on the control panel anticlockwise to decrease the depth range of the 2D image and the
ultrasound image is magnied.
NOTE:
• The frame rate varies with the depth.
• The range of the scanning depth varies with the probe. D (depth) is displayed in the 2D Image Info area
and is represented in unit of cm.
■ Frequency
The probe is capable of generating a broadband signal with a certain start frequency and a certain bandwidth. A
higher frequency brings about higher resolution and lower penetration.
To adjust the frequency:
●
Tap the left part of
Frequency
on the touch screen to decrease the value.
●
Tap the right part of
Frequency
on the touch screen to increase the value.
■ Chroma
Chroma is used to colorize the gray scale image to enhance the discrimination capability.
To adjust the chroma:
Tap the left or right part of
Chroma
on the touch screen to make a setting.
■ 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.
Tap
Compound
on the touch screen to enable or disable the compound imaging function.
■ Line 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.
