Abstract
Background: It can be challenging to adequately visualise standard smooth-surfaced needles 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 visualised. This study proposes an objective method for comparing different needle modifications in order to determine which modifications are best visualised in ultrasound images.
Methodology: A standard smooth-surfaced needle was mathematically modeled at different angles. The needle visibility was simulated using the ultrasound program Field II and gray-scale images were generated.
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.
