This study introduces a new AI network, the Semantic-aware Breast Tumors Segmentation Network (SBTSN), for more accurate breast cancer detection in ultrasound images. SBTSN improves tumor boundary identification, aiding early diagnosis and better patient outcomes.

Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Oncology

Background:

  • Breast cancer poses a significant health risk to women globally.
  • Early detection through ultrasound is crucial for improving survival rates.
  • Ultrasound images present challenges like low contrast and blurry boundaries, hindering accurate tumor segmentation.

Purpose of the Study:

  • To develop an advanced AI model for precise breast tumor segmentation in ultrasound images.
  • To address limitations of current methods in handling image quality issues and tumor variability.
  • To enhance the accuracy and efficiency of automated breast cancer detection.

Main Methods:

  • Proposed the Semantic-aware Breast Tumors Segmentation Network (SBTSN), a U-Net-based architecture.

  • Introduced a novel Semantic-aware Block (SAB) to refine tumor boundaries using semantic guidance.
  • Implemented dynamic attention mechanisms within the SAB to focus on relevant features and reduce noise.

    • Main Results:

    • SBTSN demonstrated superior performance over state-of-the-art models on BUSI and STU datasets.
    • Achieved high scores in Dice and Intersection over Union (IoU) segmentation metrics.
    • Effectively reduced missed detections in complex clinical scenarios, showing improved accuracy.

    Conclusions:

    • The SBTSN offers a robust solution for accurate breast tumor segmentation in ultrasound imaging.
    • The novel SAB effectively enhances boundary refinement and feature discrimination.
    • SBTSN provides a balance of high accuracy and computational efficiency for clinical applications.
