Background:

Convolutional neural networks (CNNs) are widely used for medical image segmentation.
Existing methods may not fully capture multi-scale and spatial information effectively.

Purpose of the Study:

To introduce the pyramid channel coordinate attention (PCCA) module for improved medical image segmentation.
To enhance semantic segmentation networks by integrating multi-scale and spatial information.

Main Methods:

Developed the PCCA module to fuse multi-scale features in the channel direction.
Aggregated local and global channel information with spatial location information.
Integrated the PCCA module into existing semantic segmentation networks.

Main Results:

Achieved state-of-the-art results on medical image segmentation tasks.
Demonstrated superior performance on the LiTS, ISIC-2018, and CX datasets.
The PCCA module effectively fuses multi-scale and spatial information.

Conclusions:

The PCCA module offers a significant advancement in medical image segmentation.
This attention mechanism improves the performance of CNN-based segmentation networks.
The proposed method shows great potential for clinical applications.
