Background:

Computed Tomography (CT) window setting is crucial for image analysis.
Existing methods lack domain-invariant and interpretable approaches for automated CT window setting.

Purpose of the Study:

To develop a plug-and-play module for automatic CT window setting in neural networks.
To enable deployment of medical imaging AI without manual CT window configuration.

Main Methods:

A novel module derived from the Tanh activation function was proposed.
The module integrates seamlessly with existing medical imaging neural network backbones.
A domain-invariant design allows for intuitive observation of adaptive mechanism preferences.

Main Results:

The method was validated on multiple open-source datasets, showing significant improvements in segmentation.
Achieved 54%–127%+ Dice, 14%–32%+ Recall, and 94%–200%+ Precision on challenging segmentation tasks.
Demonstrated efficient deployment of AI-powered medical imaging tasks in an NVIDIA NGC environment.

Conclusions:

The proposed method automates CT window settings for downstream tasks in medical imaging AI.
This reduces deployment costs and facilitates the development of mainstream medical imaging neural networks.
