Area of Science:

Medical Imaging
Computer Vision
Artificial Intelligence

Background:

Transformer-based methods like TransUNet and SwinUNet are used for medical image segmentation.
Current high-to-low resolution networks can lose crucial low-level semantic information during encoding.

Purpose of the Study:

To propose a new framework, MR-Trans, that maintains high- and low-resolution feature representations simultaneously.
To improve medical image segmentation accuracy by addressing information loss in existing methods.

Main Methods:

MR-Trans utilizes a branch partition module to create multi-resolution branches.
An encoder module with Swin Transformer extracts long-range dependencies, and a novel feature fusion strategy is employed.
A decoder module combines PSPNet and FPNet for enhanced multi-scale recognition.

Main Results:

MR-Trans demonstrated superior performance compared to state-of-the-art methods on two medical image segmentation datasets.
The proposed method effectively preserves low-level semantic information lost in traditional high-to-low resolution networks.

Conclusions:

MR-Trans offers an effective approach to medical image segmentation by preserving multi-resolution features.
The framework shows significant potential for advancing the field of medical image analysis and segmentation.
