Tap [Exit] and the system exits the guide line verification status.
13.2.6 iNeedle (Needle Visualization Enhancement )
In the course of biopsy, the metal needle attached to the probe is punctured into the tissue with a
certain angle; because of the needle acoustic impedance, the ultrasonic beam cannot penetrate the
metal 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 angle can be chosen
by users.
iNeedle is an option.
NOTE: only L14-3Ws, L20-5s, L9-3s, C6-2Gs, C11-3s, SC6-1s, SC6-1E, and L13-3Ns probes support
the function.
