Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Human-Computer Interaction

Background:

  • Image-guided surgery (IGS) enhances minimally invasive procedures but often requires surgeons to shift attention to monitors, potentially impairing cognitive and motor tasks.
  • Attention shifts during surgery can negatively impact performance and patient outcomes.
  • Augmented reality (AR) offers a potential solution by overlaying virtual patient data onto the real-world surgical view.

Purpose of the Study:

  • To evaluate the impact of different augmented reality (AR) image-guided surgery (IGS) setups compared to traditional navigation on surgeon attention shifts during craniotomy planning.
  • To assess user experience and performance differences between mobile AR, desktop AR, and traditional navigation systems.

Main Methods:

  • A study was conducted comparing two AR IGS setups (mobile and desktop) against traditional navigation for craniotomy planning.
  • Key metrics included task completion time and the number of attention shifts observed.
  • User feedback on system usability and perceived performance was also collected.

Main Results:

  • A significant difference in task time and attention shifts was found between traditional navigation and AR systems.
  • No significant differences in attention shifts were observed between the mobile AR and desktop AR setups.
  • Users reported higher ease of use and better performance with the mobile AR system.

Conclusions:

  • Augmented reality (AR) technology shows promise in reducing attention shifts for surgeons during image-guided procedures, regardless of the visualization setup.
  • AR may lead to more streamlined and focused surgical procedures by minimizing the need for surgeons to divert their attention.
  • Mobile AR systems may offer specific user experience advantages in terms of perceived usability and performance.
