Stainless Steel Echogenic Tip Needles

The ultrasound market hit a tipping point about 5 years ago when three things met at a critical point: image quality, portability, and price point. Physicians had access to high quality, reasonably priced portable ultrasound machines, which meant that they could start using ultrasound as a tool in their practices, surgeries, and general office work. Since then, the portable/hand-carried market has exploded.

It can be challenging to adequately visualise standard smooth-surfaced needles at steep angles of insertion. The angle-dependency is sought to be decreased by subjecting needle surfaces to different modifications, however, there are too few summative studies to unambiguously reveal which modifications are best. This study proposes an objective method for potentially comparing different needle modifications to determine which are most echogenic in ultrasound images. Methodology A standard smooth-surfaced needle was mathematically modeled at different angles. The needle visibility was assessed from ultrasound images generated by the ultrasound program Field II. Results The visibility of the needle diminished with increasing angles relative to the transducer. Discussion Field II simulations were conducted as if the needle appeared in completely homogeneous medium. Such ideal conditions are rarely present and can, at best, be compared to experiments conducted in homogenous gels or water baths. Conclusion The visibility from a standard smooth-surfaced needle was successfully simulated at different angles using the ultrasound simulation program Field II. Results are comparable to experiments conducted in gels or water baths. This method has the potential to objectively compare different needle modifications to determine, which modifications are best visualized in ultrasound images.
