Abstract

Computer generative method has been used for long time in brain tumor segmentation tasks on magnetic resonance images. The popularity of machine learning also prompts people to explore the use of generative methods to better train their segmentation models. At the early stage, brain tumor segmentation competitions like BraTS 2012 used computer synthetic MR images with tumor to solve the lack of enough data in the training set, and now, with the rise of computer generative models in deep learning, more researchers have started to work on this track to find a better solution for the task. This thesis addresses the implementation and analysis of some existing methods, specifically a tumor synthetic tool called TumorSim and a competition winning deep learning model that incorporates variational auto-encoder as a generative model. This thesis also reports on an experiment that uses imperfect segmented tumors from simple models as the input to a generative adversarial network to generate a better result.
