Background:

• Accurate brain tumor classification is crucial for effective treatment and patient outcomes.
• Manual classification of tumors from MRI scans is time-consuming and prone to errors.
• Deep learning offers a promising avenue for automating and improving the accuracy of medical image analysis.

Purpose of the Study:

• To develop and evaluate a deep learning approach for classifying brain tumors using MRI data.
• To assist neurologists in making faster and more accurate diagnoses.
• To improve upon existing state-of-the-art techniques in brain tumor classification.

Main Methods:

• A deep learning model, a finetuned VGG19 (19 layered Visual Geometric Group) network, was employed for classification.
• Brain tumor segmentation was performed using k-means clustering.
• Synthetic data augmentation was utilized to increase the training dataset size and improve classifier performance.

Main Results:

• The proposed deep learning approach demonstrated high accuracy in classifying brain tumors from MRI scans.
• The method achieved superior performance compared to previously reported state-of-the-art techniques on the BraTS 2015 dataset.
• The integration of k-means clustering and VGG19 with data augmentation proved effective.

Conclusions:

• The developed deep learning strategy offers an effective and efficient solution for brain tumor classification.
• This automated approach can significantly aid neurologists in clinical diagnosis, potentially leading to earlier and more effective treatment.
• The study highlights the potential of AI in advancing medical diagnostics and image analysis.
