Area of Science:

  • Medical Imaging
  • Artificial Intelligence

Background:

  • Radiologists use manual markers (e.g., crosses, pluses) on thyroid ultrasound images to denote nodule locations.
  • Deep learning models for computer-aided detection (CAD) in thyroid ultrasound analyze image textures.
  • Manual markers act as strong prior knowledge, interfering with CAD systems' judgment and leading to overfitting.

Purpose of the Study:

  • To propose a novel cascade marker removal algorithm for thyroid ultrasound images.
  • To eliminate the interference of manual markers on deep learning-based CAD systems.
  • To enhance the focus of CAD models on pathological tissue features.

Main Methods:

  • A three-part cascade algorithm: feature extraction, mask correction, and marker removal.
  • Feature extraction highlights salient features to emphasize markers.
  • Mask correction isolates marker features, and marker removal eliminates them without damaging semantic information.

Main Results:

  • The algorithm enables classification, segmentation, and object detection models to concentrate on pathological tissue features.
  • Demonstrates superior performance on thyroid ultrasound images compared to mainstream image inpainting algorithms.
  • Improves the stability and performance of computer-aided detection systems in both marked and unmarked images.

Conclusions:

  • The proposed cascade marker removal algorithm effectively eliminates manual marker interference in thyroid ultrasound images.
  • Enhances the diagnostic accuracy and reliability of deep learning-based CAD systems.
  • Significantly contributes to the advancement of automated thyroid nodule analysis.
