About Steep Needle Profiling technology

The SNP control turns on Steep Needle Profiling technology, which enhances linear structures within a
selected angle range and can facilitate needle guidance during catheter placement and nerve-block
procedures. A three- or four-sided outline indicates the enhancement area as shown in
page 4-11.
For curved array transducers, Steep Needle Profiling technology can help identify the direction of the needle,
although only segments of the needle shaft may show in the image. See
movement and fluid injection to help verify the needle-tip location.
The SNP control is available in 2D full-screen imaging only and on the following:

To avoid incorrect needle placement when Steep Needle Profiling (SNP) is on:
Use only FUJIFILM SonoSite or CIVCO approved needle guides, brackets,
supplies, components, and accessories. Other brands may not properly fit
FUJIFILM SonoSite transducers.
Use only needle guides compatible with the transducers listed in
"Transducers and exam types available with SNP"
Using movement and fluid injection, verify the needle-tip location and trajectory.
Steep Needle Profiling technology enhances linear structures within a selected
angle range on the ultrasound plane. Linear structures outside the selected
angle range or the ultrasound plane
apparent.
Note that linear structures are enhanced only in an outlined portion of the image.
The area outside the outline remains unchanged.
Note that the beam divergence of a curved array transducer may prevent a
segment of the needle shaft from showing in the image. The needle tip may not
show.
