Background:

  • Accurate pathological diagnosis of gastric cancer is crucial for effective treatment.
  • Traditional methods can be subjective and time-consuming.
  • Hyperspectral imaging offers detailed tissue analysis beyond standard microscopy.

Purpose of the Study:

  • To apply microscopic hyperspectral imaging and deep learning for gastric cancer diagnosis.
  • To develop a robust method for differentiating cancerous from normal gastric tissue.
  • To establish a hyperspectral database for gastric cancer research.

Main Methods:

  • Collected microscopic hyperspectral images from 30 gastric cancer patients.
  • Developed a deep learning model analyzing spectral-spatial features (410-910 nm).
  • Investigated individual tissue differences and joint spectral-spatial characteristics.

Main Results:

  • Achieved 97.57% classification accuracy for cancerous vs. normal gastric tissue.
  • Demonstrated high sensitivity (97.19%) and specificity (97.96%) for gastric cancer detection.
  • Convolutional Neural Networks (CNNs) effectively extracted deep spectral-spatial features.

Conclusions:

  • Deep learning models integrated with hyperspectral analysis provide a powerful tool for gastric cancer pathology.
  • This method enhances diagnostic accuracy and efficiency in pathological examination.
