A commonly proposed use case of AR-HMDs is to display data in image-guided interventions. Although technical feasibility has been thoroughly shown, effects of AR-HMDs on interventions are not yet well researched, hampering clinical applicability. Therefore, the goal of this study is to better understand the benefits and limitations of this technology in ultrasound-guided interventions.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>We used an AR-HMD system (based on the first-generation Microsoft <jats:italic>Hololens<\/jats:italic>) which overlays live ultrasound images spatially correctly at the location of the ultrasound transducer. We chose ultrasound-guided needle placements as a representative task for image-guided interventions. To examine the effects of the AR-HMD, we used mixed methods and conducted two studies in a lab setting: (1) In a randomized crossover study, we asked participants to place needles into a training model and evaluated task duration and accuracy with the AR-HMD as compared to the standard procedure without visual overlay and (2) in a qualitative study, we analyzed the user experience with AR-HMD using think-aloud protocols during ultrasound examinations and semi-structured interviews after the task.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Participants (<jats:italic>n<\/jats:italic>\u2009=\u200920) placed needles more accurately (mean error of 7.4\u00a0mm vs. 4.9\u00a0mm, <jats:italic>p\u2009<\/jats:italic>=\u20090.022) but not significantly faster (mean task duration of 74.4\u00a0s vs. 66.4\u00a0s, <jats:italic>p\u2009<\/jats:italic>=\u20090.211) with the AR-HMD. All participants in the <jats:italic>qualitative study<\/jats:italic> (<jats:italic>n\u2009<\/jats:italic>=\u20096) reported limitations of and unfamiliarity with the AR-HMD, yet all but one also clearly noted benefits and\/or that they would like to test the technology in practice.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>We present additional, though still preliminary, evidence that AR-HMDs provide benefits in image-guided procedures.
