Augmented Reality in Interventional Radiology: A Review of Systems, Ergonomics, Applications, and Outcomes

Area of Science:

• Medical Imaging
• Surgical Technology
• Interventional Radiology

Background:

• Traditional interventional radiology (IR) relies on 2D imaging, posing challenges for procedural precision and operator comfort.
• Augmented reality (AR) technology offers a novel solution by overlaying digital imaging data onto the real-world view.
• This can potentially enhance visualization and improve the user experience during IR procedures.

Purpose of the Study:

• To review current augmented reality (AR) systems used in interventional radiology (IR).
• To examine the impact of AR on procedural workflow, operator ergonomics, and clinical outcomes.
• To identify limitations and future directions for AR in IR.

Main Methods:

• A narrative literature review was conducted.
• Studies investigating AR applications in IR were included.
• Articles unrelated to IR procedures were excluded.

Main Results:

• AR systems show potential for improved operator ergonomics, including better depth perception and reduced eye strain.
• Clinical studies indicate reductions in radiation exposure and procedure times with AR compared to standard methods.
• AR demonstrated comparable accuracy to conventional techniques, with good overall operator tolerability.

Conclusions:

• Augmented reality (AR) presents a promising advancement for interventional radiology (IR), enhancing ergonomics and potentially improving efficiency and safety.
• Current evidence suggests benefits in radiation reduction and procedural speed, though further research is required.
• Limitations include a need for more extensive clinical data and standardized evaluation metrics for AR in IR.
