Area of Science:

  • Medical Imaging
  • Computer Vision
  • Artificial Intelligence

Background:

  • Medical image segmentation is vital for analyzing lesions and anatomical structures.
  • Current deep learning models, like Convolutional Neural Networks (CNNs), face limitations in modeling global dependencies due to fixed kernel sizes and restricted receptive fields.
  • While Vision Transformers offer global perception, they often incur high computational costs, limiting their use in resource-constrained medical settings.

Purpose of the Study:

  • To develop a multi-dimensional, lightweight, attention-enhanced model for medical image segmentation.
  • To address the limitations of existing methods in capturing global dependencies and computational efficiency.
  • To provide a practical and valuable tool for clinical medical imaging analysis.

  • The proposed model integrates omni-dimensional dynamic convolution and mask attention.
  • Omni-dimensional dynamic convolution enables adaptive modeling across spatial, channel, and kernel-number dimensions, expanding the effective receptive field.
  • Mask attention utilizes binary masks to suppress background noise and enhance focus on critical image boundaries, achieving lower computational cost than global self-attention.

Main Results:

  • The model was evaluated on three public benchmark datasets for medical image segmentation.
  • It demonstrated superior or comparable segmentation accuracy and inference efficiency against current mainstream methods.
  • The results highlight the model's effectiveness in improving segmentation performance.

Conclusions:

  • The developed model offers a computationally efficient and accurate solution for medical image segmentation.
  • Its ability to expand the effective receptive field and focus on critical boundaries makes it highly applicable.
  • The findings suggest significant potential for practical clinical adoption in medical imaging analysis.
