Note: When the virtual needle image changes from yellow to violet, it does NOT necessarily mean that you have
advanced your needle beyond the target structure, it means the needle is beyond the ultrasound plane.
Caution: To avoid reduced needle tracking accuracy, prior to insertion, do NOT modify the straightness of the
needle by bending.
Caution: During insertion, use a light touch to prevent needle deflection and/or bending. Needle deflection and/or
needle bending ay reduce needle tracking accuracy.
