Augmented Reality Visualization Using Image-Overlay for MR-guided Interventions: System Description, Feasibility, and Initial Evaluation in a Spine Phantom

Objective: The purpose of this article is to provide a preliminary user assessment of Image-Overlay, an augmented reality system for MRI-guided needle placement, in a spine phantom.

Conclusion: Image-Overlay can be used to successfully target lumbar facet joints with high accuracy and minimal insertions. This is potentially useful for other interventional MRI applications. Additional clinical assessment is needed.
