Summary
A new smartphone augmented reality (AR) solution offers a low-cost, efficient, and accurate method for locating intracranial lesions in neurosurgery, proving effective in resource-limited settings.
Area of Science:
- Neurosurgery
- Medical Technology
- Augmented Reality
Background:
- Neuronavigation is essential for intracranial lesion localization but is often unaffordable in resource-limited areas.
- Mobile augmented reality (AR) presents a promising low-cost alternative, though accuracy improvements are needed.
Purpose of the Study:
- To explore a novel smartphone AR solution for intracranial lesion localization.
- To evaluate the performance of a new AR application with refined reference markers.
Main Methods:
- A smartphone AR solution and standard neuronavigation were used to locate intracranial lesions in 38 patients.
- Key metrics included time, deviation of lesion centers, and ratio of overlap region (ROR) between methods.
Main Results:
- AR localization was significantly faster (256.61s vs. 454.16s) and accurate (81.57% rate, 3.55mm deviation, 75.03% ROR).
- Efficiency and accuracy of AR improved with experience, showing reduced time and deviation, and increased ROR in later stages.
Conclusions:
- Smartphone AR offers a practical and reliable method for locating small intracranial lesions.
- This solution is particularly valuable in settings lacking access to traditional neuronavigation systems.
