Background and Objective Electromagnetic navigation technology has demonstrated significant potential in enhancing the accuracy and safety of neurosurgical procedures. However, traditional electromagnetic navigation systems face challenges such as high equipment costs, complex operation, bulky size, and insufficient anti-interference performance. To address these limitations, our study developed and validated a novel portable electromagnetic neuronavigation system designed to improve the precision, accessibility, and clinical applicability of electromagnetic navigation technology in cranial surgery.
Methods The software and hardware architecture of a portable neural magnetic navigation system was designed. The key technologies of the system were analysed, including electromagnetic positioning algorithms, miniaturized sensor design, optimization of electromagnetic positioning and navigation algorithms, anti-interference signal processing methods, and fast three-dimensional reconstruction algorithms. A prototype was developed, and its accuracy was tested. Finally, a preliminary clinical application evaluation was conducted.
Results This study successfully developed a comprehensive portable electromagnetic neuronavigation system capable of achieving preoperative planning, intraoperative real-time positioning and navigation, and postoperative evaluation of navigation outcomes. Through rigorous collaborative testing of the system’s software and hardware, the accuracy of electromagnetic neuronavigation has been validated to meet clinical requirements.
Conclusions This study developed a portable neuroelectromagnetic navigation system and validated its effectiveness and safety through rigorous model testing and preliminary clinical applications. The system is characterized by its compact size, high precision, excellent portability, and user-friendly operation, making it highly valuable for promoting navigation technology and advancing the precision and minimally invasive nature of neurosurgical procedures.
