Abstract:
Gliomas are the most common and aggressive malignant primary brain tumors. Automatic brain tumor segmentation from multi-modality magnetic resonance images using deep learning methods is critical for gliomas diagnosis. Deep learning segmentation architectures, especially based on fully convolutional neural network, have proved great performance on medical image segmentation. However, these approaches cannot explicitly model global information and overlook the topology structure of lesion regions, which leaves room for improvement. In this paper, we propose a convolution-and-transformer network (COTRNet) to explicitly capture global information and a topology aware loss to constrain the network to learn topological information. Moreover, we exploit transfer learning by using pretrained parameters on ImageNet and deep supervision by adding multi-level predictions to further improve the segmentation performance. COTRNet achieved dice scores of 78.08%, 76.18%, and 83.92% in the enhancing tumor, the tumor core, and the whole tumor segmentation on brain tumor segmentation challenge 2021. Experimental results demonstrated effectiveness of the proposed method. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
