The DDTI dataset contains 637 ultrasound thyroid images with pixel-level labels from a single device, provided by Pedraza and others. Thyroid ultrasound image analysis is a continuously expanding field, primarily due to the difficulty of nodule detection in ultrasound. The value of this database lies in the diagnostic diversity and the variety of cases it includes, such as thyroiditis, goiters, nodules, and cancer. The complexity of the images and their interpretation reflects the need to develop strategies to support the diagnostic and prognostic process. Thyroid nodule segmentation in ultrasound images is a valuable and challenging task, which is significant for the diagnosis of thyroid cancer.

The file structure of the DDTI dataset is as follows. The DDTI dataset consists of two folders: "1_or_data" and "2_preprocessed_data." The former is the folder for original data, while the latter is for data that has been preprocessed. The primary data statistics are mainly based on "1_or_data," and all files end with a .png extension. The specific file architecture is as follows:
