Brain tumours are the second commonest form of childhood malignancy while medulloblastoma is the most common brain tumor in children. Accurate Segmentation of medulloblastoma is necessary for maximum tumor surgical removal. We proposed a novel method to segment medulloblastoma by modifying signed pressure function (SPF) function in Gaussians Filtering Regularized Level Set (SBGRLS) method. Quantitative validation is performed in this project. The method is proved to be clinical-oriented which is fast, robust, accurate with minimal user interaction.
