Background:

Thyroid nodules are early indicators of thyroid cancer, necessitating accurate segmentation for early diagnosis and treatment.
Ultrasound imaging of thyroid nodules presents challenges like speckle noise, low contrast, and resolution, hindering precise segmentation.

Purpose of the Study:

To develop a novel framework for improving the accuracy of ultrasound thyroid nodule segmentation.
To enhance early diagnosis and treatment of thyroid cancer through precise nodule characterization.

Main Methods:

A super-resolution reconstruction network was employed to upscale ultrasound image resolution.
A proposed N-shape network, incorporating atrous spatial pyramid pooling, attention blocks, and a parallel atrous convolution module, was used for segmentation.

Main Results:

The proposed method achieved a Dice score of 91.9%, mIoU of 87.0%, Precision of 88.0%, Recall of 83.7%, and F1-score of 84.3%.
The framework demonstrated superior performance compared to existing state-of-the-art methods on the UTNI-2021 dataset.

Conclusions:

The novel framework offers a significant advancement in ultrasound image segmentation for thyroid nodules.
This method provides reliable auxiliary diagnostic information for clinicians, aiding in thyroid cancer management.
