Brain Tumor Detection using Hybrid CNN in fMRI images

Abstract

One of the deadliest brain tumors in the world. Both adults and children are at risk for the disease. Depending on their position, appearance and shape, it has a low survival rate and is available in different varieties. Incorrect classification of the brain tumor will have negative consequences. Early detection of the tumor type and stage is necessary for selecting a specific treatment. Identifying brain tumors can be done effectively by examining fMRI, or functional magnetic resonance imaging. Due to the various information and various types of tumors in brain, the manual process takes lot of time to identify, and there may be chances of human error. Therefore, it is necessary to have an intelligent diagnostic system. The recent evolution of image categorization systems has been influenced by the use of deep convolution neural networks (CNN). In this research work, a new hybrid paradigm with images combines a convolution neural network (CNN) and a masked autoencoder for distribution estimation (MADE). Three different forms of brain tumors were tested using T1-weighted contrast enhanced images. The CNN-MADE hybrid's excellent classification performance is demonstrated by the results, despite the limited availability of medical images. A new layered model was proposed to categorize brain tumors through MRI. The proposed approach is more successful than the alternatives based on the experiments' results.
