Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Agreement between participants’ subjective assessment of needle tip visibility on a 5-point Likert scale and the objectively quantified echogenicity of the cannula, measured as standardized grayscale intensity (RGB-based brightness analysis) at three predefined points along the cannula in ultrasound images. | — |
Secondary
| Measure | Time frame |
|---|---|
| -Assessment of the perceived safety of further needle advancement based on needle visibility in the ultrasound images -Analysis of the influence of puncture angle on needle tip visibility Comparison of assessments between phantom and cadaver models -Evaluation of the impact of prior experience and self-reported ultrasound skills on needle tip assessment -Assessment of the perceived difficulty in evaluating needle position in the presented ultrasound images -Analysis of the influence of the needle used on needle tip visibility Comparison of assessments between phantom and cadaver models | — |
