Abstract:
This study evaluates the accuracy of heuristic methods for cranial point localization compared to the International 10/20 System, considering head morphology variations. Using 250 head models (125 female, 125 male) from the HumanShape website, measurements of Head Circumference (HC), Nasion-Inion (Ns-In), and Tragus-Tragus (LPA-RPA) distances were analyzed. A Python script in FreeCAD automated cranial point localization. Results show that while heuristic methods offer practicality, discrepancies can arise due to individual head measurements. The EPlacement device demonstrated consistent and reliable results across various head shapes, suggesting it could standardize and improve the accuracy of cranial point localization in clinical practice.
