needle, a reflecting boundary is formed. As in Figure 1, if the deflection angle is very large, the needle
display is not clear.
In the condition of deflected ultrasonic transmission, the beam direction is perpendicular to the needle
direction, and the reflection direction will be the same with the needle, as shown in Figure 2, when the
needle display in the ultrasound image is very clear. The system provides an additional deflection
transmission that is approximately perpendicular to the metal needle, as the normal transmission
(perpendicular to the transducer surface) is contained as well. And the deflection angel can be chosen
by users.
iNeedle is an option.
NOTE: only linear probe supports the function.
