Inspired by the success of Convolutional Neural Networks (CNN), we develop a\nnovel Computer Aided Detection (CADe) system using CNN for Glioblastoma\nMultiforme (GBM) detection and segmentation from multi channel MRI data. A\ntwo-stage approach first identifies the presence of GBM. This is followed by a\nGBM localization in each "abnormal" MR slice. As part of the CADe system, two\nCNN architectures viz. Classification CNN (C-CNN) and Detection CNN (D-CNN) are\nemployed. The CADe system considers MRI data consisting of four sequences\n(T1, T1c, T2, and T2FLAIR) as input, and automatically\ngenerates the bounding boxes encompassing the tumor regions in each slice which\nis deemed abnormal. Experimental results demonstrate that the proposed CADe\nsystem, when used as a preliminary step before segmentation, can allow improved\ndelineation of tumor region while reducing false positives arising in normal\nareas of the brain. The GrowCut method, employed for tumor segmentation,\ntypically requires a foreground and background seed region for initialization.\nHere the algorithm is initialized with seeds automatically generated from the\noutput of the proposed CADe system, thereby resulting in improved performance\nas compared to that using random seeds.\n
