Accurate lung segmentation in CT scans is vital for diagnosing diseases like COPD and COVID-19. A new preprocessing pipeline significantly boosts U-Net model accuracy for better medical image analysis.
Area of Science:
- Medical Imaging
- Artificial Intelligence
- Computer Vision
Background:
- Accurate segmentation of lung regions in CT scans is crucial for diagnosing lung diseases such as COPD and COVID-19.
- Automated analysis of lung diseases relies heavily on precise segmentation of lung structures in medical imaging.
- Existing segmentation methods may struggle with artifacts and variations in CT image quality.
Purpose of the Study:
- To enhance the accuracy of U-Net segmentation models for lung regions in CT scans.
- To develop and validate a robust preprocessing pipeline for medical image segmentation.
- To improve the reliability of automated lung disease analysis through optimized data preparation.
Main Methods:
- A preprocessing pipeline involving CT image normalization, binarization, and morphological operations was developed.
- Region-of-interest (ROI) filtering was applied to effectively isolate lung areas.
- The preprocessed data was used to train and evaluate U-Net segmentation models.
Main Results:
- The preprocessing pipeline significantly improved segmentation quality by providing clean, consistent input data.
- Intersection over Union (IoU) and Dice coefficients exceeded 0.95 on training datasets.
- Experimental results validated the effectiveness of the proposed preprocessing strategy.
Conclusions:
- Preprocessing is a critical standalone step for optimizing deep learning-based medical image analysis.
- The developed pipeline enhances the accuracy of lung segmentation in CT scans.
- This approach holds promise for improving automated diagnosis and analysis of lung diseases.
