Abstract

The necessity to develop fast, robust and accurate brain MR segmentation tools that require few parameters to adjust is essential since manual segmentation performed by neurologists is a time-consuming task. Among automatic methods, Deep Learning approaches have outperformed the state-of-the-art in many computer vision problems. Deep Learning techniques major disadvantage is that they usually require large amounts of labeled data for training, which is not available in medical image segmentation problems.This M.Sc. research project intends to investigate the use of Deep Learning techniques applied to brain structure segmentation in MR imaging. Two specic applications will be investigated: the brain extraction, also known as skull-stripping, and corpus callosum (CC) segmentation problems. Our method aims to use the Simultaneous Truth and Performance Level Estimation (STAPLE) algorithm to generate labeled data and use it as input for a Convolutional Neural Network (CNN). We will compare our methodology with the state-of-the-art techniques for brain and CC segmentation. (AU)
