Background:

Deep learning for brain tumor segmentation is a key research area.
Existing models like U-Net face challenges in segmenting fine details and utilizing feature information effectively.

Purpose of the Study:

To enhance brain tumor segmentation accuracy using an improved deep learning approach.
To address limitations in edge detail segmentation and feature information reuse in current models.

Main Methods:

Proposed a serial encoding-decoding U-Net structure with hybrid dilated convolution (HDC) modules.
Implemented concatenation between serial network modules and introduced a novel loss function for difficult-to-segment samples.
Evaluated performance using metrics including Intersection over Union (IOU), Precision, Dice, Hausdorff95, and Average Surface Distance (ASD).

Main Results:

The proposed model demonstrated superior performance across all evaluated metrics compared to existing segmentation models.
Segmentation results showed closer adherence to ground truth, capturing finer brain tumor details than other methods.
The algorithm achieved enhanced semantic segmentation capabilities.

Conclusions:

The developed algorithm offers improved semantic segmentation performance for brain tumors.
This technology can significantly aid in brain tumor diagnosis, supporting better patient treatment planning.
