Abstract
Brain tumor is a condition of abnormal growth of brain cells that can lead to death. Early detection is important for tumor patterns in Magnetic Resonance Imaging (MRI) images. Early detection is done by separating tumor cell details through 3D image segmentation with labels of background, non-enhancing tumor, peritumeral edema, and enhancing tumor. 3D image segmentation can be done automatically by utilizing the Convolutional Neural Network (CNN) method. The CNN architecture that is often used in 3D image segmentation is the 3D U-Net architecture. In the 3D U-Net encoder, the feature extraction process consists of a convolution block and a downsampling process. Downsampling reduces the spatial dimension which causes loss of detail information and vanishing gradient. This research proposes a modified 3D U-Net architecture with the addition of Dense Block and Block Inception in the encoder part to overcome vanishing gradient without increasing the number of parameters. The average performance results on accuracy, sensitivity, specificity, IoU, and f1-score with respective values of 99.05%, 93.37%, 98.69%, 87.7%, 92.4%. The results obtained accuracy performance on each label reached more than 95%, indicating the architecture was able to perform segmentation very well. Sensitivity and f1-score values on tumor enhancing labels are still below 90%, which means the model is still limited in detecting these parts optimally. The IoU value on the background label reaches more than 90%, while the non-enhancing tumor, peritumeral edema, and enhancing tumor labels are still below 90%, indicating that the tumor area prediction is smaller than the ground truth. The results of this study show that the 3D Dense-Inception U-Net architecture is able to perform segmentation well. However, IoU enhancement is needed to improve the quality of brain tumor segmentation.
