Background:

Manual segmentation of multimodal brain tumors is time-consuming and challenging.
Accurate segmentation is crucial for clinical treatment decisions and surgical planning.
Deep learning faces challenges in medical image segmentation due to tumor diversity and limited computational resources.

Purpose of the Study:

To develop an automatic and accurate method for segmenting multimodal brain tumors.
To improve the performance of neural network segmentation using a novel feature fusion module and attention mechanism.
To address the category imbalance problem in medical image segmentation.

Main Methods:

Proposed a feature fusion module based on a hierarchical decoupling convolution network and an attention mechanism.
Replaced U-shaped network skip connections with the feature fusion module.
Introduced a global attention mechanism to integrate encoder features and explore context information.

Main Results:

Achieved Dice similarity coefficient (DSC) of 0.775 (enhance tumor), 0.900 (whole tumor), and 0.827 (tumor core) on the BraTS 2019 dataset.
Achieved DSC of 0.800 (enhance tumor), 0.902 (whole tumor), and 0.841 (tumor core) on the BraTS 2018 dataset.
Demonstrated the method's generality and effectiveness for brain tumor image studies.

Conclusions:

The proposed method offers a powerful tool for brain tumor image analysis.
The feature fusion module and attention mechanism effectively improve segmentation accuracy.
The approach provides a general solution for complex medical image segmentation tasks.
