5-6 Image Optimization
Focus
Description
Refers to adjusting the focus of the ultrasonic beams, using the symbols
which are displayed to the right of the image.
Operations Adjust the focus number through [Focus Number] on the menu.
Tap [-] or [+] to change the value slightly or drag the control directly.
Drag on the right part of the image area to change the focus position.
In B mode, the available focus number can be switched between 1-4.
Effects The area that is focused will be of a higher contrast and resolution.
Impacts The greater the number of focal zones, the slower the frame rate.
Image Adjustment
Description More information can be obtained without moving the probe or changing the
sampling position.
FOV (Field
of View) Adjust through [FOV Size (%)] on the menu.
Tap [-] or [+] to change the value slightly or drag the control directly.
You can get a much larger field of view when selecting a larger FOV.
The frame rate decreases when using a larger FOV.
B Steer Steer the probe by tapping buttons on the bottom of the image area.
ExFOV
(Extended
FOV) Adjust through [ExFOV] on the menu. Off represents no ExFOV effect.
For linear probes, the ExFOV function displays as trapezoid imaging.
For convex probes, the ExFOV function displays as extending the scanning
angle.
Impacts The FOV range is available only for convex and phased probes.
The ExFOV function is available only for convex and phased probes.
When ExFOV function is turned on, [FOV Size (%)] cannot be changed.
The B Steer function is available only for linear probes.
Rotation/Invert (U/D Flip and L/R Flip)
Description The function provides better observation for image display.
Rotation Rotate the image using the [Rotation] control.
Images can be rotated by 0°, 90°, 180° and 270°.
Invert (U/D
Flip and L/R
Flip) To invert the image horizontally or vertically.
Invert the image using the [L/R Flip]/[U/D Flip] control: tap [Up]/ [Down]/ [Left]/
[Right] to invert the image at different directions.
Effects You can identify the image orientation using the “m” mark on the screen. By
default, the “m” mark is located in the top-left corner of the image.
