Needle Size And Angle; Additional Recommendations - FujiFilm SonoSite X-Porte User Manual

Curved transducer: Use the following table to determine the needle angle setting to use. Needle
angles are measured in relation to the surface of the transducer.

3 Insert the needle toward the angle guide.
4 (Optional) Tap Off to turn off Needle Profiling.
Temporarily turning off Needle Profiling can help you identify artifacts and other structures not of interest.
Tap On to turn it on again.

Needle size and angle

Use a 17-gauge to 25-gauge needle (recommended). Enhancement results can depend on the type and
brand of needle used. For more information, consult the medical literature on needle visibility in
ultrasound-guided procedures.
You can angle the needle up to 50° from the transducer surface. Beyond 50°, the needle may be less
enhanced. (Needle Profiling has little or no benefit to out-of-plane procedures. Needle Profiling is intended
for in-plane procedures only.)

For best results, angle the needle only up to 50° from the transducer surface.

Additional recommendations

Avoid setting the gain too high when using Needle Profiling, as unnecessarily high gain can cause artifacts
in the image. Also, respiratory and cardiac movement in the image may cause bright pulsating artifacts.
