Quantifying attention shifts in augmented reality image‐guided neurosurgery

Abstract

Image-guided surgery (IGS) has allowed for more minimally invasive procedures, leading to better patient outcomes, reduced risk of infection, less pain, shorter hospital stays and faster recoveries. One drawback that has emerged with IGS is that the surgeon must shift their attention from the patient to the monitor for guidance. Yet both cognitive and motor tasks are negatively affected with attention shifts. Augmented reality (AR), which merges the realworld surgical scene with preoperative virtual patient images and plans, has been proposed as a solution to this drawback. In this work, we studied the impact of two different types of AR IGS set-ups (mobile AR and desktop AR) and traditional navigation on attention shifts for the specific task of craniotomy planning. We found a significant difference in terms of the time taken to perform the task and attention shifts between traditional navigation, but no significant difference between the different AR set-ups. With mobile AR, however, users felt that the system was easier to use and that their performance was better. These results suggest that regardless of where the AR visualisation is shown to the surgeon, AR may reduce attention shifts, leading to more streamlined and focused procedures.

Surgery guided by mixed reality: presentation of a proof of concept

“…This provides a gain in accuracy and safety in the procedurem which finally might result in time-saving and correct positioning of the implant (Léger et al. 2017 , Vávra et al. 2017 ).…”

“…The voice- and image-activated command is easy to use, without latency or excessive repetition (Léger et al. 2017 ). The image quality, contrast and stability are good enough not to cause tiredness or motion sickness.…”

CIGuide: in situ augmented reality laser guidance

“…Similar approaches are known, the ARSys Tricorder [4], or the Probaris system [5], none of which have found widespread use in daily surgical routine, presumably due to the additional constraints introduced to surgical workflow (e.g., eye calibration or wearing AR glasses intraoperatively). When considering attention shift [6,7] and depth-perception [8], Spatial AR systems have an advantage over conventional displays or seethrough AR systems [9][10][11]. More recently, microscope and instrument-mounted projectors have been used to provide spatial augmented reality guidance with image projection [12][13][14], or instrument-mounted displays [15] to ease instrument alignment.…”
