Brain Tumor Segmentation is a medical image analysis task that involves the separation of brain tumors from normal brain tissue in magnetic resonance imaging (MRI) scans. The goal of brain tumor segmentation is to produce a binary or multi-class segmentation map that accurately reflects the location and extent of the tumor.

A novel attention gate (AG) model for medical imaging that automatically learns to focus on target structures of varying shapes and sizes is proposed to eliminate the necessity of using explicit external tissue/organ localisation modules of cascaded convolutional neural networks (CNNs).
A fast and accurate fully automatic method for brain tumor segmentation which is competitive both in terms of accuracy and speed compared to the state of the art, and introduces a novel cascaded architecture that allows the system to more accurately model local label dependencies.
A cascade of fully convolutional neural networks is proposed to segment multi-modal Magnetic Resonance images with brain tumor into background and three hierarchical regions: whole tumor, tumor core and enhancing tumor core to decompose the multi-class segmentation problem into a sequence of three binary segmentation problems according to the subregion hierarchy.
This paper presents the most recent effort on developing a robust segmentation algorithm in the form of a convolutional neural network that beats the current state of the art on BraTS 2015, is one of the leading methods on the BraTS 2017 validation set and achieves good Dice scores on the test set.
Due to a limited training dataset size, a variational auto-encoder branch is added to reconstruct the input image itself in order to regularize the shared decoder and impose additional constraints on its layers.
A fully automatic way to quantify tumor imaging characteristics using deep learning-based segmentation and test whether these characteristics are predictive of tumor genomic subtypes is proposed.
A two-stage encoder-decoder based model for brain tumor subregional segmentation that adopts attention gates and is trained additionally using an expanded dataset formed by the first-stage outputs is proposed.
By incorporating BraTS-specific modifications regarding postprocessing, region-based training, a more aggressive data augmentation as well as several minor modifications to the nnUNet pipeline, nnU-Net is able to improve its segmentation performance substantially.
A trusted brain tumor segmentation network which can generate robust segmentation results and reliable uncertainty estimations without excessive computational burden and modification of the backbone network is proposed.
The proposed autofocus convolutional layer for semantic segmentation with the objective of enhancing the capabilities of neural networks for multi-scale processing can be easily integrated into existing networks to improve a model's representational power.
