Опубликована: Янв. 20, 2025

Brain tumor identification through Bio-medical magnetic resonance imaging (MRI) presents a critical challenge in diagnostic imaging, where high accuracy is essential for informed treatment planning. Traditional methods face limitations segmentation precision, leading to increased misdiagnosis risks. This study introduces hybrid deep-learning model integrating Vision Transformer (ViT) and Capsule Network (CapsNet) improve brain classification accuracy. The aims enhance sensitivity specificity categorization. Utilising the BRATS2020 dataset, which comprises 6,000 MRI scans across four classes (meningioma, glioma, pituitary tumor, no tumor), dataset was divided into an 80-20 training-testing split. Data pre-processing included scaling, normalization, feature augmentation robustness. ViT-CapsNet assessed alongside individual ViT CapsNet performance using accuracy, recall, F1-score, AUC-ROC metrics. achieved of 90%, precision recall 89%, F1-score 89.5%, outperforming models. yielded 4-5% improvement types, with notable gains gliomas tumors. Unlike prior methods, achieving 88% our demonstrates superior 90%. approach offers promising solution more accurate detection. Future research could explore refining fusion techniques, advanced interpretability expanding model’s application various clinical environments.
