Detailed Description
This is a randomised, blinded interventional prospective study which will be conducted and reported as per the Consolidated Standards of Reporting Trials - Artificial Intelligence (CONSORT-AI) guidance. The study end points have been defined prospectively, and data will be divided into two cohorts (with vs without ScanNav Anatomy PNB assistance). Participants will be asked to perform ultrasound (US) scanning on healthy volunteers while under observation by a subject matter expert (expert observer) who will assess participant performance, both with and without the device. The US scans will be recorded and blinded expert observers (without knowledge of whether ScanNav Anatomy PNB is in use) will also assess acquisition of an appropriate block view (panel of three experts, one viewing each scan as per the unblinded assessors). The initial assessment will be undertaken after a scanning tutorial and then repeated after 8-10 weeks (to assess longer-term impact of the device).

Outcome Measures
Primary Outcome Measures
- Block identification (long-term) [8-10 weeks]
Identification of an appropriate block view by participant [blinded expert's opinion; Y/N] both with and without the use of ScanNav Anatomy PNB for ultrasound scanning (8 - 10 weeks after teaching)
Secondary Outcome Measures
- Block identification (immediate) [Time 0]
Identification of an appropriate block view by participant [blinded expert's opinion; Y/N] both with and without the use of ScanNav Anatomy PNB for ultrasound scanning (immediately after teaching)
- Anatomy identification [Time 0 and 8-10 weeks]
Correct identification of anatomical structures on the block view [Y/N]
- Participant confidence [Time 0 and 8-10 weeks]
Participant confidence in ultrasound scanning [continuous scale; 0 (no confidence] - 10 (total confidence)]
- Overall scan performance [Time 0 and 8-10 weeks]
Expert observer's assessment of the participant's overall ultrasound scanning performance [continuous scale; 0 (poor) - 10 (excellent)]
