BRAIN TUMOR DETECTION USING CONVOLUTIONAL NEURAL NETWORKS

Abstract

The block chain based execution of EMR is a secured transaction and maintaining of medical records in various hospitals. Now technology has developed, but the technology in the medical record transaction has not developed. Still now, each hospital is maintaining a separate database to maintain their patient details. Whenthe patient moved to another hospital, they need to carry document each and every time. If they missed the document they need to take all the report from starting. It takes more time and cost. To avoid this, we need to maintain the globalized databaseto store the data in secure manner using block chain technology. Here the donor database also connected to it, when there is any emergency in the organ transplantation and any blood requirement, the hospital can approach the donor who are connected to this system and get the immediate transaction. It also reduces the time to get the donor at the necessary time. This project helps us to connect the hospitals and the voluntary organization under the one umbrella. This system maintains security in block by using Ethereum.

Deployment and User Interface:
Develop a user-friendly application for clinicians to use the model.
Ensure the system can be deployed in clinical settings with ease.
Detailed Description:
1. Data Collection and Preprocessing:
Data Sources: Obtain MRI brain scan datasets from medical institutions, public repositories (e.g., The Cancer Imaging Archive), or collaboration with healthcare partners.
Image Enhancement: Apply preprocessing techniques such as noise reduction, contrast enhancement, and normalization to improve image quality.
Image Augmentation: Use data augmentation techniques (e.g., rotation, flipping, zooming) to increase the diversity of training data and improve model robustness.
Annotation: Ensure the datasets are accurately labeled with the presence or absence of tumors and, if applicable, tumor types and locations.
2. CNN Model Development:
Architecture Selection: Start with popular CNN architectures like VGG16, ResNet, or Inception and modify them to suit the specific requirements of brain tumor detection.
Custom Layers: Develop custom layers if necessary to better capture the features specific to brain tumor images.
Training: Train the CNN models using the preprocessed MRI images. Use techniques like batch normalization, dropout, and regularization to enhance model performance and prevent overfitting.
Hyperparameter Tuning: Optimize hyperparameters (e.g., learning rate, batch size, number of epochs) using methods like grid search or random search.
3. Model Evaluation and Validation:
Evaluation Metrics: Use metrics such as accuracy, precision, recall, F1-score, and Area Under the Curve (AUC) to assess model performance.
Cross-Validation: Implement k-fold cross-validation to ensure the model generalizes well to unseen data.
Independent Testing: Validate the model on independent test datasets to confirm its robustness and real-world applicability.
Confusion Matrix: Analyze the confusion matrix to understand the types of errors the model is making and improve upon them.
4. Deployment and User Interface:
Model Deployment: Deploy the trained model on cloud platforms (e.g., AWS, Google Cloud) or on-premises servers to ensure scalability and accessibility.
User Interface: Develop a web-based or desktop application that allows clinicians to upload MRI images and receive tumor detection results. Ensure the interface is intuitive and provides clear visualization of predictions.
Integration with PACS: Integrate the system with Picture Archiving and Communication Systems (PACS) used in hospitals for seamless access to MRI scans.
Security and Privacy: Implement robust security measures to protect patient data and ensure compliance with regulations like HIPAA.
Expected Outcomes:
Accurate Tumor Detection: High accuracy in detecting and classifying brain tumors from MRI images.
Clinical Utility: A practical tool that aids radiologists and clinicians in diagnosing brain tumors, leading to timely and effective treatment.
