7. Adjusting Ultrasound Image Quality
To adjust desired scanning parameter, click corresponding button at the bottom of software window
and do sweeps on ultrasound image (depending on control type). Control types were described in section
“Types of Controls” of this document. All scanning parameters will be described in next sections. If any
parameter is controlled using other method, then this information will be presented in the section that
describes this parameter. Buttons of scanning parameters are organized to multiple rows, and to show other
parameters (that are not initially visible) must be done vertical sweeps on buttons placement area.
7.1. Adjusting B Mode Controls
7.1.1. Focus
Description
Focus optimizes the ultrasound image by increasing the resolution of specific areas. Always try to
adjust focuses so that focusing markers are at the center of the anatomical structure which is of most interest.
Values
The available list of focusing depth values depends on the probe used. Focusing depth
measurement units used - millimeters (mm).
Adjustment
To change focusing depth, wait while scanning controls will become inactive and then do vertical
sweeps with finger along vertical B mode scale line.
Relations to other controls
After adjusting Depth you may need to adjust the Focus controls.
7.1.2. Depth
Description
Depth adjusts the field of view. Increase the depth to look at larger or deeper structures. Decrease
depth in order to look at structures near the skin surface. Additionally, you may wish to decrease the depth if
there is a large part of unnecessary ultrasound image below the displayed anatomical structures of interest.
You may also need to change the depth in order to see anatomical structures of interest in the center of the
screen.
