Abstract
Augmented Reality (AR) technology offers promising applications in healthcare by enabling interactive 3D visualization of anatomical structures. However, current AR implementations often lack patient-specific detail, limiting their effectiveness in clinical settings. In this paper, we present BrainAR, an innovative mobile AR-based application designed for the automatic segmentation, 3D visualization, localization, and interaction with brain tumors using multiparametric 3D Magnetic Resonance Imaging (MRI) data. Our method leverages a 3D Residual U-Net, trained on the BraTS2021 dataset, achieving a mean Dice score of 0.886 for accurate tumor segmentation. The segmentation outputs are integrated into a real-time 3D engine to enable precise and dynamic visualization of brain tumors. Key contributions of our work include: 1) a server-side deployment of the segmentation model for online, patient-specific inference; 2) seamless AR integration enabling interactive exploration through hand gestures and voice commands; and 3) a mobile-based platform aimed at enhancing accessibility and usability in clinical environments. The proposed solution facilitates early detection and diagnosis by providing clinicians with an intuitive, immersive, and patient-specific tool for enhanced medical imaging interaction.
