A Product Evaluation of Augmented Reality Equipment Coupled to Diagnostic Medical Sonography: A Potential Equipment and Ergonomic Innovation

Abstract

Objective: The aim of this product evaluation was to investigate the workflow and occupational health benefits of implementing augmented reality (AR) technology (MediView XR Inc, Cleveland, OH) paired with a portable ultrasound equipment system. Materials and Method: A diverse sample of sonography users was consented and ranged in experience levels. They were asked to complete a video training session, a hands-on demonstration, and remote instruction while using the augmented reality ultrasound (AR US) system. The duration of participants’ tasks was assessed during the use of both AR US and the 2-dimensional ultrasound (2D US) system. Participants’ postures and positions were evaluated using the Rapid Upper Limb Assessment (RULA), which assessed ergonomic risk factors, linked to body position and muscle usage. Participants also completed the System Usability Scale (SUS). Finally, participants were invited to complete a qualitative interview session, regarding the use of the AR US system. Results: A total of 20 participants provided data after using both the AR US and 2D US systems. The assessment data revealed positive SUS scores, which reflected favorably on both the product, education, and the training provided. The time spent on simulated work (20 minutes), with both imaging systems, remained consistent. The Rapid Upper Limb Assessment tool (RULA) scores for the cohort indicated a lower (better) median upper body score when using the AR US system. The cohort also had a statistically significant lower median subscore for the neck, trunk, and legs, compared with 2D US ( p < 0.00). Conclusion: Although larger studies are necessary to validate these findings, this cohort identified several opportunities for integrating the AR US system. Preliminary evidence suggests that an AR US system may offer occupational health benefits, as part of the imaging workflow.
