Brain Tumor Segmentation in MRI Images

This contains the MATLAB code for Tumor Segmentation from Brain MRI pictures. The calculation depends on Morphological activities, so is quick enough in handling. The dataset contains T1-weighted contrast-enhanced images with three kinds of brain tumor.

Project Description

Brain tumor segmentation in MRI images is a crucial step in the diagnosis and treatment of brain tumors. MRI (magnetic resonance imaging) is a non-invasive medical imaging technique that uses a magnetic field, radio waves, and a computer to produce detailed images of the brain. These images can be used to identify and segment brain tumors, which are abnormal growths of cells in the brain.

The process of brain tumor segmentation in MRI images involves several steps. First, the MRI images are acquired, typically using a 3D T1-weighted sequence. This sequence provides high-resolution images of the brain that can be used to identify the location and size of the tumor. Next, the images are pre-processed to remove noise and enhance the contrast between the tumor and surrounding tissue.

Once the images are pre-processed, the next step is to segment the tumor. This is typically done using a combination of manual and automatic methods. Manual segmentation involves a radiologist or a trained expert manually outlining the tumor on the images using specialized software. Automatic segmentation, on the other hand, uses algorithms and machine learning techniques to automatically identify and segment the tumor.

The combination of manual and automatic methods is typically used to achieve the best results. The manual segmentation provides a more accurate and detailed segmentation of the tumor, while the automatic segmentation provides a more efficient and objective segmentation.

Once the tumor is segmented, the next step is to extract quantitative information about the tumor, such as its size, shape, and location. This information is used to diagnose the tumor and plan its treatment. For example, a large and irregularly shaped tumor may indicate a more aggressive form of cancer, while a small and symmetrical tumor may indicate a benign tumor.
