Use this control to adjust the resolution of your image by adjusting how many lines of
image data the transducer acquires over your image area.
The higher you set the line density, the lower the acquisition frame rate. Because of
this trade off, you might find that higher line density is most useful for examining
features in tissue that do not move very much.
Use this control to change the magnification level of the area that is shown when a
measurement or annotation is being placed.
Sets the image orientation, allowing you to align the image with the transducer. The
blue dot in the corner of the control panel image area and clinical display image
corresponds to this setting.
Tap either of the orientation controls to toggle the orientation between the following
options: Left/Right and Up/Down.
