Current Accuracy of Augmented Reality Neuronavigation Systems: Systematic Review and Meta-Analysis

Augmented reality neuronavigation (ARN) systems can overlay three-dimensional anatomy and disease without the need for a two-dimensional external monitor. Accuracy is crucial their clinical applicability. We performed systematic review regarding reported accuracy of ARN compared them with conventional infrared (CIN). PubMed Embase were searched CIN systems. For ARN, type system, method patient-to-image registration, method, system noted. CIN, navigation accuracy, expressed as target registration error (TRE), was A meta-analysis comparing TRE Thirty-five studies included, 12 23 CIN. could be divided into head-mounted display heads-up display. In 4 methods encountered which point-pair matching one most frequently used. Five assessing described. Ninety-four measurements 9058 Mean 2.5 mm (95% confidence interval, 0.7–4.4) 2.6 2.1–3.1) there seems to lack agreement best assess accuracy. Nevertheless, seem able achieve an comparable Future should prospective compare TREs, measured in standardized fashion.
