Project Title: Microwave Medical Image Segmentation for Brain Stroke Diagnosis: Imaging-Process-Informed Image Processing
Project Overview:
The aim of this project is to develop an innovative image segmentation method using microwave imaging technology to enhance the diagnosis of brain strokes. By leveraging the unique properties of microwave signals, we seek to improve the accuracy and efficiency of image processing in medical diagnostics, enabling early detection and treatment of strokes.
Introduction:
Stroke is one of the leading causes of disability and mortality worldwide. Timely diagnosis is crucial in stroke management, as it directly influences treatment options and patient outcomes. Traditional imaging modalities, such as CT and MRI, while effective, often come with high costs and accessibility issues, especially in low-resource settings. Microwave imaging offers a promising alternative due to its non-invasive nature, lower costs, and portability. This project focuses on developing a robust image segmentation framework specifically designed for microwave brain images, incorporating insights from the imaging process to enhance the quality of the segmentation.
Objectives:
1. Develop a Microwave Imaging System: Design and implement a microwave imaging system tailored for brain imaging, ensuring the setup meets the requirements for effective stroke detection.
2. Image Acquisition and Preprocessing: Establish protocols for acquiring high-quality microwave images of the brain. Implement preprocessing techniques to enhance image quality and prepare them for segmentation.
3. Segmentation Algorithm Design: Develop advanced image segmentation algorithms that utilize information from the imaging process. This includes machine learning techniques that can adapt to variations in microwave image characteristics.
4. Validation and Comparison: Carry out extensive validation of the segmentation results against conventional imaging techniques (CT/MRI). The comparison will include metrics such as accuracy, sensitivity, specificity, and computational efficiency.
5. Clinical Integration and Testing: Collaborate with medical professionals to integrate the developed segmentation system into clinical workflows. Conduct pilot studies to evaluate its effectiveness in real-world settings.
