Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Computer Vision

Background:

  • Traditional CT image segmentation faces accuracy challenges due to low contrast and high noise.
  • Existing deep learning models struggle with precise edge segmentation and pixel classification errors.

Purpose of the Study:

  • To propose the Medical Images Segment Net (MIS-Net) model for improved CT image segmentation.
  • To enhance the accuracy of lung and liver edge segmentation in medical images.

Main Methods:

  • Developed MIS-Net, a deep learning model featuring a symmetric encoding-decoding structure.
  • Incorporated multi-scale atrous convolution for comprehensive multi-scale feature extraction from CT images.

Main Results:

  • Achieved a Dice Similarity Coefficient (DSC) of 97.61% for left and right lung segmentation on the COVID-19 CT Lung and Infection Segmentation dataset.
  • Attained a DSC of 98.78% for liver segmentation on the Liver Tumor Segmentation Challenge 2017 dataset.

Conclusions:

  • MIS-Net effectively addresses limitations in traditional and deep learning-based CT image segmentation.
  • The model demonstrates high accuracy in segmenting lung and liver regions, validated on public datasets.
