The depth scale marker allows to determine the depth of the echoes or objects displayed in
the ultrasound image on sent or printed images.
Three depth scale markers are available:
•
Large marker: represents 5cm in depth
•
Medium marker: represents 1cm in depth
•
Small marker: represents 5mm in depth
Screen reference: 3
A triangular marker next to the depth scale marks the middle of a focal zone of the ultrasound
probe. The Foc. Zones control adjusts the number of focal zones. The Foc. Pos. control
positions the focal zone markers along the depth scale. The markers only represent the B-
image focal zone(s). The number of focal zones and number of focal depth positions is
dependent on the ultrasound probe.
